Advantages of Presentations  

Effective communication  

One of the primary advantages of Presentations is their ability to facilitate effective communication. Whether you're addressing a small group of colleagues or a large audience at a conference, Presentations help you to convey your message clearly and succinctly. By structuring your content and using visuals, you can ensure that your key points are highlighted and easily understood by the audience. 

Visual appeal  

"Seeing is believing," and Presentations capitalise on this aspect of human psychology. The use of visuals, such as charts, graphs, images, and videos, enhances the overall appeal of the content. These visual aids not only make the information more engaging but also help reinforce the main ideas, making the Presentation more memorable for the audience. 

Engaging the audience  

Captivating your audience's attention is crucial for effective communication. Presentations provide ample opportunities to engage your listeners through various means. By incorporating storytelling, anecdotes, and real-life examples, you can nurture an emotional connection with your audience. Additionally, interactive elements like polls, quizzes, and group activities keep the audience actively involved throughout the Presentation. 

Simplifying complex information  

Complex ideas and data can often be overwhelming, making it challenging to convey them effectively. However, Presentations excel in simplifying intricate information. By breaking down complex concepts into digestible and interconnected slides, you can present the information in a logical sequence, ensuring that the audience grasps the content more easily. 

Persuasive impact  

Presentations are powerful tools for persuasion and influence. Whether you're convincing potential clients to invest in your product, advocating for a particular cause, or delivering a motivational speech, a well-crafted Presentation can sway the audience's opinions and inspire action. The combination of visual and verbal elements enables you to make a compelling case for your ideas, leaving a lasting impact on the listeners. 

Versatility in delivery methods  

Another advantage of Presentations lies in their flexibility and versatility in terms of delivery methods. Gone are the days when Presentations were limited to in-person meetings. Today, technology allows presenters to reach a wider audience through various platforms, including webinars, online videos, and virtual conferences. This adaptability makes Presentations an ideal choice for modern communication needs. 

Enhanced understanding and retention  

When information is presented in a visually appealing and structured manner, it aids in better understanding and retention. Human brains process visuals faster and more effectively than plain text, making Presentations an ideal medium for conveying complex concepts. The combination of visual elements and spoken words create a multi-sensory experience, leading to increased information retention among the audience. 

Professionalism and credibility  

In professional settings, well-designed Presentations lend an air of credibility and professionalism to the presenter and the topic being discussed. A thoughtfully crafted Presentation shows that the presenter has put effort into preparing and organising the content, which in turn enhances the audience's trust and receptiveness to the information presented.

Disadvantages of Presentations  

Time-consuming  

Creating a compelling Presentation can be a time-consuming process. From researching and gathering relevant information to designing visually appealing slides, a significant amount of effort goes into ensuring that the content is well-structured and impactful. This time investment can be challenging, especially when presenters have tight schedules or are faced with last-minute Presentation requests. 

Technical glitches  

Presentations heavily rely on technology, and technical glitches can quickly turn a well-prepared Presentation into a frustrating experience. Projectors may malfunction, slides might not load correctly, or audiovisual components may fail to work as expected. Dealing with such technical issues during a Presentation can disrupt the flow and distract both the presenter and the audience. 

Overdependence on technology  

In some cases, presenters may become overly reliant on the visuals and technology, neglecting the importance of direct engagement with the audience. Overloaded slides with excessive text can make presenters read directly from the slides, undermining the personal connection and interaction with the listeners. This overdependence on technology can lead to a lack of spontaneity and authenticity during the Presentation. 

Lack of interactivity  

Traditional Presentations, particularly those delivered in large auditoriums, may lack interactivity and real-time feedback. In comparison, modern Presentation formats can incorporate interactive elements; not all Presentations provide opportunities for audience participation or discussions. This one-sided communication can lead to reduced engagement and limited opportunities for clarifying doubts or addressing queries. 

Public speaking anxiety  

For many individuals, public speaking can be a nerve-wracking experience. Presenting in front of an audience, especially in formal settings, can trigger anxiety and stage fright. This anxiety may affect the presenter's delivery and confidence, impacting the overall effectiveness of the Presentation. Overcoming public speaking anxiety requires practice, self-assurance, and effective stress management techniques. 

Not suitable for all topics  

While Presentations are an excellent medium for conveying certain types of information, they may not be suitable for all topics. Some subjects require in-depth discussions, hands-on demonstrations, or interactive workshops, which may not align well with the traditional slide-based Presentation format. Choosing the appropriate communication method for specific topics is crucial to ensure effective knowledge transfer and engagement. 

Accessibility concerns  

In a diverse audience, some individuals may face challenges in accessing and comprehending Presentation materials. For instance, people with visual impairments may find it difficult to interpret visual elements, while those with hearing impairments may struggle to follow the spoken content without proper captions or transcripts. Addressing accessibility concerns is vital to ensure inclusivity and equal participation for all attendees. 

Information overload  

Presentations that bombard the audience with excessive information on each slide can lead to information overload. When the audience is overwhelmed with data, they may struggle to absorb and retain the key points. Presenters should strike a balance between providing adequate information and keeping the content concise and focused. 

How to make a successful Presentation?  

Now that we know the Advantages and Disadvantages of Presentations, we will provide you with some tips on how to make a successful Presentation. 

1) Know your audience: Understand your audience's needs and interests to tailor your content accordingly. 

2) Start with a strong opening: Begin with an attention-grabbing introduction to captivate the audience from the start of presentation .

3) Organise your content logically: Structure your Presentation in a clear and coherent manner with a beginning, middle, and end. 

4) Limit text on slides: Keep slides simple and avoid overcrowding with excessive text; use bullet points and keywords. 

5) Use visuals effectively: Incorporate high-quality images, graphs, and charts to enhance understanding and engagement. 

6) Practice, practice, practice: Rehearse your Presentation multiple times to improve your delivery and confidence. 

7) Be enthusiastic and confident: Show passion for your topic and maintain good eye contact to build trust with the audience. 

8) Tell stories and use examples: Include relevant anecdotes and case studies to make your points more relatable and memorable. 

9) Keep it interactive: Encourage audience participation through questions, polls, or discussions to keep them engaged. 

10) Manage time wisely: Respect the allotted time for your Presentation and pace your delivery accordingly. 

11) End with a strong conclusion: Summarise your key points and leave the audience with a clear takeaway or call to action. 

Conclusion  

All in all, Presentations have altered the way we communicate and share information. While they offer numerous advantages, such as effective communication, visual appeal, and persuasive impact, they also come with their share of disadvantages, including technical challenges and public speaking anxiety. By understanding the advantages and disadvantages of presentations and employing best practices, we can Improve Presesntation Skills , create engaging and impactful presentations that leave a lasting impression on the audience.

Communication Skills - Advantages and Disadvantages of Presentations

Some managers hold the mistaken belief that routine progress reports to their team must be formally presented. In reality, it is best to ask yourself if sitting in a presentation is the most productive use of your team's time. If your answer is 'No' then send an email or intranet file to convey to your team the same information without interrupting or reducing your team's productivity.

If your answer is 'Yes' then you need to spend the time properly planning what actually needs to be presented and keeping a tight control on the scope of the presentation. It is usually a better idea to give a presentation only when you have something exceptional or urgent to report, or something that would benefit from being delivered face to face .

The principal advantage of any presentation is that you can interact with your audience. If you are presenting information in a document, on the other hand, you have to make certain assumptions about your audience. This means that you present your topics and arguments in such a way that meets the preconceived image you have of the audience. If your assumptions are incorrect, then the information that you send out may not have the effect you want it to.

The second advantage is that when presenting you are able to observe the reactions of the audience based on their body language and can thus revise certain elements of your delivery on the spot. For example:

If you notice a lot of blank looks when you are presenting a certain point then you can address this by going into more detail or providing context so that everyone understands what you are saying.

In addition to helping you immediately gauge your audience's degree of understanding, a presentation allows you to assess the level of acceptance of or resistance to what you are saying. For example:

Making a short presentation to your team about a proposed change in working practices can give you a good indication of whether the change is going to be readily accepted or not.

This facet of presentations should not be overlooked because it offers you an immediate insight into the prevailing mood. By picking up on nonverbal signals within your audience you can try to address any concerns that people might have.

The number of ways you can emphasize your key points is much greater in a presentation than a written report. In a document you can only repeat or place emphasis on a point once. In a presentation you can do both of these things, plus you can alter the style of your delivery to suit the needs of your audience and message, which is extremely useful.

Examples of ways to emphasize key points in a presentation include:

• Using pauses, speaking more loudly, becoming more animated, or moving closer to the audience.

Another advantage of presentations is that you can use visual aids to explain and describe your points, and thus help your audience to fully comprehend your message. For example,

• Visual Aids enable the presenter to: • Use interactive illustrations • Build up an image to aid understanding of concepts • Show a sample or prototype • Draw attention to or emphasize key elements • Use pictures or diagrams instead of words.

As a presenter you can also include demonstrations. This can be particularly useful for things like software or physical products. This enables you to tell a story in a more engaging way than you can in a formal document.

Finally, when you make a presentation you know exactly who has attended and you are able to assess their degree of comprehension through questioning and observation. This is impossible with a written report because you have no way of gauging the level of understanding your recipients have gained. Some people may have only scanned it and others may have not read it at all.

Whilst there are many advantages to presenting your message, these must be weighed against the limitations of this form of communication. Most notable is the fact that your audience only has this one opportunity to hear and understand your message. In many working environments it is impractical to have everyone attend a single meeting so you will have to rely on those who attended passing on the information, or you will have to present your message more than once.

If your presentation does not have a handout then attendees will have no formal point of reference to use in the future. So a presentation does not always mean that you can avoid preparing a document; in some instances you will have to do both. Some of the audience may have taken notes but how do you know if these notes are an accurate reflection of your message? They also have no way of rereading or passing on your message as they would if it was written in a document.

Audiences often like to have access to background information to help them understand issues and problems. You simply do not have the time to provide all this during your presentation, but you can provide references and a glossary within a handout to support this need. Such tools will help you to overcome the problem of presenting to an audience where the individuals have differing levels of understanding and expertise.

An obvious limitation of presentations is that their effectiveness relies on the ability of the speaker to deliver the message. The speaker also may not be able to set a pace appropriate to the audience's level of understanding.

Many good speakers lose their audience's attention because their preferred style is to have questions only at the end. Whilst allowing questions at the end is often recommended, it runs the risk that your audience will switch off from what you are saying or forget a valuable question or query by the time you have finished your presentation. As an effective presenter there are several simple techniques you can use to avoid this. For example:

You can prompt for questions at the end of each point or section of your presentation. You can note questions as they arise on a flip chart so nothing is lost.

After making a judgment on whether or not a presentation is the most effective and productive way for you to convey your message you need to carefully plan it. You need to clearly define its aim and key message. You also need to make sure that you understand your audience and ensure your presentation overcomes as many of the limitations as possible.

By working through the stages of planning a presentation outlined in the next section you can ensure that your presentation achieves its aim.

10 Common Presentation Mistakes

Avoiding Common Pitfalls in Your Presentations

By the Mind Tools Content Team

Most of us have experienced dull, irrelevant or confusing presentations. But think back to the last really great presentation you saw – one that was informative, motivating and inspiring. Wouldn't you love to be able to present like that?

This article looks at 10 of the most common mistakes that speakers make when giving presentations. By avoiding these, you'll make your presentations stand out – for all of the right reasons, and none of the wrong ones.

Mistake 1: Not Preparing Enough

Steve Jobs was a famously inspiring speaker. His speeches may have looked effortless, but, in reality, each one took days or weeks of preparation.

Careful preparation is essential. The amount of time you spend on planning depends on your situation, but it's a good idea to start early – you can never be too well-prepared.

Proper preparation also helps you to manage presentation nerves . When you know your material inside and out, you're far less likely to feel nervous. Our presentation planning checklist and Skillbook " Even Better Presentations " can help you to plan your next event properly.

Mistake 2: Not Familiarizing Yourself With the Venue and Equipment

Imagine that your presentation starts in an hour. You arrive at the venue and, to your horror, the projector won't work with your laptop. The slides you spent hours preparing are useless. This is a disaster!

You can avoid a situation like this by taking time to familiarize yourself with the venue and available equipment at least once before your presentation.

Often, the sorts of problems that can jeopardize your presentation will be situations beyond your control, but this doesn't mean that you're helpless. Conduct a risk analysis to identify potential issues, and come up with a good "Plan B" for each one.

Mistake 3: Ignoring Your Audience

Sometimes, speakers can get so wrapped up in delivering their presentations that they forget about the needs of their audience.

Start your presentation by telling your audience what to expect. Let them know what you'll cover first, whether and when you'll stop for a break, if you'll be taking questions during the presentation, and so on.

Providing these "signposts" up front will give your audience a clear idea of what to expect, so that they can relax and concentrate on your presentation.

Mistake 4: Using Inappropriate Content

The primary purpose of any presentation is to share information with others, so it's important to consider the level you'll pitch it at.

Do some research on your audience. Why are they here? How much do they already know about your topic, and what do they most want to learn from you? It's no use giving a presentation that's so full of jargon that no one understands you. But you wouldn't want to patronize people, either.

Try to put yourself in people's shoes, to get a clearer idea about their needs and motivations. You can also greet individuals as they arrive on the day, and ask questions to get a feel for their level of knowledge. This will also help you to personalize your presentation and make a connection with each person in your audience, so that they'll be more attentive to what you say.

Mistake 5: Being Too Verbose

Short, concise presentations are often more powerful than verbose ones. Try to limit yourself to a few main points. If you take too long getting to your point, you risk losing your audience's attention.

The average adult has a 15- to 20-minute attention span. So, if you want to keep your audience engaged, stick to the point! During the planning phase, make a note of the themes you want to cover and how you want to get them across. Then, when you start filling out the details, ask yourself: "Does my audience really need to know this?"

Our articles on the 7 Cs of Communication and Communications Planning have more tips for communicating in a clear, concise way.

Mistake 6: Using Ineffective Visuals

Poor slides can spoil a good presentation, so it's worth spending time getting yours right.

We've all seen slides with garish colors, unnecessary animation, or fonts that are too small to read. The most effective presentation visuals aren't flashy – they're concise and consistent.

When choosing colors, think about where the presentation will take place. A dark background with light or white text works best in dark rooms, while a white background with dark text is easier to see in a brightly lit room.

Choose your pictures carefully, too. High-quality graphics can clarify complex information and lift an otherwise plain screen, but low-quality images can make your presentation appear unprofessional. Unless an image is contributing something, embrace the negative space – less clutter means greater understanding. Use animation sparingly, too – a dancing logo or emoji will only distract your audience.

Mistake 7: Overcrowding Text

The best rule of thumb for text is to keep it simple . Don't try to cram too much information into your slides. Aim for a maximum of three to four words within each bullet point, and no more than three bullets per slide.

This doesn't mean that you should spread your content over dozens of slides. Limit yourself to 10 slides or fewer for a 30-minute presentation. Look at each slide, story or graph carefully. Ask yourself what it adds to the presentation, and remove it if it isn't important.

Mistake 8: Speaking Incoherently

Even though we spend a significant part of the day talking to one another, speaking to an audience is a surprisingly difficult skill, and it's one that we need to practice.

If nerves make you rush through a presentation, your audience could miss your most important points. Use centering or deep breathing techniques to suppress the urge to rush. If you do begin to babble, take a moment to collect yourself. Breathe deeply, and enunciate each word clearly, while you focus on speaking more slowly.

Our article on better public speaking has strategies and tips that you can use to become a more engaging speaker. One useful technique is storytelling – stories can be powerful tools for inspiring and engaging others. Our Expert Interviews with Annette Simmons and Paul Smith have tips that you can use to tell great stories.

Mistake 9: Showing a Lack of Dynamism

Another common mistake is to freeze in one spot for the duration of your presentation.

Some presenters feel most comfortable behind the podium. Try to emulate great speakers like Steve Jobs , who moved purposefully around the stage during his presentations.

As well as working the stage, he used gestures and body language to communicate his excitement and passion for his subject. Pay attention to what your hands are doing – they're important for communicating emotion. But only use gestures if they feel natural, and avoid being too flamboyant with your arms, unless you want to make your audience laugh!

See our Expert Interview, " Winning Body Language ," to learn more about body language and what it says to your audience.

Mistake 10: Avoiding Eye Contact

Have you ever been to a presentation where the speaker spent all of their time looking at their notes, the screen, the floor, or even at the ceiling? How did this make you feel?

Meeting a person's gaze establishes a personal connection, and even a quick glance can keep people engaged. If your audience is small enough, try to make eye contact with each individual at least once.

If the audience is too large for this, try looking at people's foreheads. The individual may not interpret it as eye contact, but those sitting around them will.

It takes practice and effort to deliver a good presentation. But, if you know how to avoid the pitfalls, your presentations will be great.

Common presentation mistakes include not preparing properly, delivering inappropriate content, and speaking poorly.

Time spent on careful planning always pays dividends. Check out the venue, and familiarize yourself with equipment in advance to avoid possible problems.

Keep your content clear and concise, with visual aids to match. And make sure that you pitch it at the right level for your audience's understanding, so that your presentation doesn't patronize or bewilder.

Remember, public speaking is a performance. Practice speaking clearly with a slower pace than your normal speech to avoid "rapid-fire" delivery. Use eye contact, body language and gestures that complement your message to keep your audience engaged.

The 6 types of presentation (and why you need them)

Hrideep barot.

• Presentation , Public Speaking

We all have been exposed to different types of presentations right from school years.

Group presentations, lectures by teachers and professors, seminars, webinars or online presentations, e-learning, e-conferences, etc., are all different types of presentations that we come across in our daily lives.

But each of them work for different settings.

In this article, we will take a look at 6 such types of presentations and when and why you need them.

1. Informative Presentations

This is the most common type of presentation, be it in an educational setting or business or corporate setting.

The aim of an informative presentation is to give detailed information about a product, concept, or idea to a specific kind of audience.

They are often analytical or require a rational analysis of the data presented.

Training sessions or one-day workshops are good examples where this kind of presentation is used.

Here is an example of an informative presentation on public speaking and presentations.

Now, there are different situations where you can use informative presentations.

a) Reporting

Although a report is a written explanation of an event, it can also be verbal.

A perfect place to use informative presentations is news reporting , as it requires the presenter to present information systematically.

b) Briefing

This involves explaining both positive and negative aspects of a particular topic in a few words.

It is providing information quickly and effectively about an issue to influence decisions or to come to solutions.

Hence, the decision-making bodies of an organization can make use of this kind of presentation to save time and effectively come to conclusions.

c) Research

Informative presentations are often used to present research findings to a specific audience , as it involves reporting the findings and briefing it to the audience.

Hence, almost everywhere where research takes place, be it in an educational context or occupational , can make use of this kind of presentation.

Tips for giving informative presentations

• As there would be a lot of technical information and statistics, focus on the main points or agenda first and if you have more time, you can add them at the end
• Keep your presentation simple and clear . Avoid complex sentence structures and graphics
• Tell the outline of your presentation briefly in the introduction for a better flow
• Make sure that your presentation does not stretch for too long. 10-15 minutes is what your audience can concentrate on
• Restate your keyphrase at the end and briefly summarize all the important points of your presentation

Speech topics for an informative presentation

• Cropping techniques
• Organic Farming
• Corporate Farming
• Hydroponics
• Sustainable Agriculture, etc
• Climate change
• Environmental issues
• Eco-friendly ways of management
• Eco-politics
• Eco-feminism, etc
• Gender studies
• Gender and education
• Religious studies
• History of education
• Philosophy of education, etc
• Ethnic cultures
• Indigenous cultures
• Multiculturalism
• Popular culture
• Cultural trends, etc
• Business administration
• Business ethics
• Business models
• Promotion and marketing communications
• Finance, etc

2. Persuasive presentations

Persuasion is the art of motivating or convincing someone to act or make a change in their actions or thoughts.

If you are planning to give a persuasive presentation, and are looking for how to give a persuasive speech, check out our article on A Comprehensive Guide to Writing a Persuasive Speech to gain in-depth knowledge about the art of giving persuasive presentations.

Persuasive presentations are also widely used form after informative presentations.

There are various circumstances where persuasive presentations can be used.

a) Policy-making

Government bodies make use of persuasion almost every time, be it the legislative or decision-making bodies, executive bodies, or even courts.

Even election campaigns involve using persuasive presentations as an instrument of their pre-determined goals of swaying the citizens.

For that matter, any executive or management body of an organization can make use of these kinds of presentations.

b) Value judgment

This kind involves answering the question “why” and supplementing it with possible benefits.

Most Ted talks and YouTube videos try to persuade the audience and fall into the persuasive presentation category.

Even religious heads use this as a means of persuading their believers to follow their belief system.

Deciding on a procedure or telling an audience the correct procedure of doing something is another situation.

An example of a persuasive presentation

Bailey parnell: is social media hurting your mental health.

This TED talk by Bailey Parnell is a good example of a persuasive presentation.

She starts strong by asking rhetorical questions that set the mood for her further points.

We can also see how the speaker is genuinely concerned regarding the issue, engaging the audience till the end.

Tips for giving a persuasive presentation

• Start your presentation with a relevant quote or statistics about your topic to establish credibility
• Tell personal anecdotes and examples wherever necessary to develop an emotional connection with your audience
• Deliver your presentation with passion and genuine interest to motivate your audience to think
• Answer the question “why” for better understanding and clarity in your presentation
• State your viewpoint clearly and clarify doubts if your audience seems to have any

3. Demonstrative presentations

This involves demonstrating a process or the functioning of a product in a step-by-step fashion.

So, a master class on communication skills or making a product model is an example of a demonstrative presentation.

Usually, the audience is an active part of such presentations and these can work in any context where you want the audience to learn a new skill.

a) Instructions

This involves giving guidelines or steps of a process or work .

Teaching how to make a car model step-by-step is a good example where you can use this kind of informative presentation to guide your audience.

Another instance can be at the workplace , to train the employees or introduce them to a new product at work.

This type also works with demonstrating recipes and cooking workshops.

An example of demonstrative presentation

The easy guide on making just about any smoothie.

In this recipe demonstration, he tells his audience how many ingredients are involved and briefs them about the outline of his presentation at the start of his speech.

He also shows all steps in real-time so that the audience have a better understanding of the process and keeps them engaged.

Tips to give a demonstrative presentation

• Introduce your product and its function to your audience before telling them how to go about with the steps
• Explain the steps with diagrams or show them in real-time along with the audience
• Give equal time to every person in the audience for clearing doubts, if any
• Keep your introduction short. Not more than 5 minutes
• Discuss options or variations that the audience can try at the end of the presentation

Speech topics for demonstrative presentations

• How to administer CPR
• How to wrap a gift professionally
• How to budget your monthly income
• How to choose a car insurance
• How to restore a piece of antique furniture

4. Inspirational presentations

As the name suggests, this type of presentation involves inspiring others!

The main aim of an inspirational presentation is to motivate or move your audience and is also known as a motivational presentation.

Using techniques like storytelling, narrating personal anecdotes , or even humor work wonders as your audience develops an emotional connection to the message.

This TED talk by Luvvie Ajayi Jones is humorous but a lot more inspirational. Check it out!

Tips for giving an inspirational presentation

• Start with a question that will leave the audience thinking. Pause for some time and then begin with your presentation
• Develop a sense of connection by narrating personal incidents and experiences to grow empathy
• Have some main points that you want to emphasize on
• Make use of humor ! It instantly builds a connection with the listener
• Non-verbal elements like paralanguage, body language, speech modulations, tone, etc., makes a huge difference

Speech topics for an inspirational presentation

• Importance of diversity and inclusion
• Building mental resilience
• Need for change management
• Valuing small victories in life
• How procrastinating is your enemy

5. Business presentations

In the corporate world, presentations are the go-to solution to do anything: planning or strategizing, articulating company goals, screening candidates, status reports , and many more.

Let us take a dive into the different types of business presentations.

a) Sales presentation

Also known as sales pitches , sales presentations involve providing information about a product or a service to sell it.

It has a pre-defined strategy of initiating and closing the sales deal.

This can be done in person or nowadays, on the phone, or via e-communication .

b) Training sessions

Often employees have on-the-job training sessions that are aimed to increase the knowledge and skills of the employees.

This kind can also involve the audience to participate , like in demonstrative presentations.

c) Meetings

Meetings can be called for for different reasons and can be of different forms as well.

Conferences ( both video and in-person), board meetings, informal team meetings, daily reporting, etc., are all various contexts of meeting in a business setting.

d) E- presentations

E- presentations existed before the COVID pandemic as well but were used seldom.

But, with the ongoing pandemic, e-presentations or remote presentations have replaced all other types of presentations and will be with us for a while longer.

However, on the brighter side, it is an eco-friendly alternative to normal face-to-face kind of a set-up, and it also saves transportation and other costs !

e) Seminars

Seminars are widely used in the health sector , usually involving a panel of speakers on a topic. The audience is anywhere between 10 to 100.

It ends with a question and answers session , and the audience gets to take handouts with them.

f) One-on-one or 1:1

Interviews are usually one-on-one and involve presenting your achievements and capabilities to your prospective employer.

Apart from interviews, 1:1 meetings are also used in sales and marketing to crack a business deal.

Tips for giving business presentations

• Include key phrases and other important details on your slides and make them bold
• Avoid casual slangs and informal tone of speech
• If you are giving a sales presentation, explain your product or service in simple and clear words , and list the reasons why it is beneficial for your potential clients
• Make sure to be on time ! Delaying your audience will work against you and leave a bad impression on you and your company
• Know your material or content thoroughly to answer the questions asked by your audience

Speech topics for business presentations

• Implementing an Agile Project
• Introduction to data modeling
• Introduction to UML(Unified Modeling Language)
• Social Media strategies for a successful business
• Business writing for managers

6. Powerpoint presentations

PowerPoint presentations or PPTs are the most effective ones among all types of presentations simply because they are convenient and easy to understand .

They are available in different formats and are suitable to use in practically any type of presentation and context, be it business, educational, or for informal purposes.

There are various types of PowerPoint presentations that you can use depending on the context.

a) PPTs for general audience

• For general audiences, avoid using jargon terms

If you feel that you need to use them, provide the audience some background information about the field or topic being covered

• Avoid using more than 8 words per line, as anything more than that becomes difficult to remember
• Use bullets or a numbered list for better retention
• Try not to read from your PPT
• Give handouts or record your presentation in case anyone wants it

b) PPTs for teaching

• In this case, the PowerPoint is content-based
• Make sure that the words on the slides are visible
• Use bigger font and avoid fancy fonts
• Add relevant pictures and graphics to keep your audience engaged
• You can also add documentaries or relevant videos to aid in understanding

c) Repurpose PPTs

• This involves reinventing an earlier ppt or combining 1 or more than 1 PowerPoints
• Giving new touches to an earlier PPT or changing the format
• You can take any slide of your PPT and upload it on social media for growing your brand or business
• You can even convert your PPT into mp4 , i.e, video format
• You can even add voice and save the mp4 format, and you have a good marketing plan!

d) PechaKucha

• This type of PowerPoint presentation comes from the Japanese word PechaKucha meaning sound of a conversation or chit-chat
• This involves changing slides every 20 seconds
• There can be a maximum of 20 slides , which means your presentation lasts for only 6 minutes and 40 seconds
• The PPT mostly has graphics and fewer words
• This type of presentation is best suited for telling a story or a personal anecdote

e) Multimedia presentations

• This is the best kind of PPT to engage your audience
• It contains texts along with pictures, videos, infographics, music, illustrations, GIFs , and many more
• Add higher resolution images and videos , or even a 360-degree snapshot if you are in the sales and marketing industry
• Adding infographics such as charts and graphs makes the process of understanding easier and saves time
• Music in a PPT helps your audience to be relaxed, at the same time making them alert and engaged

Types of slides in a presentation

PowerPoint presentation slides are broadly classified into 3 categories: Text, Visual, and Mixed slides.

1. Text slides

As the name suggests, this category of slides involve words or texts.

You can format the text as plain sentences or pointers.

You may even arrange them all in a single slide or one line per slide.

The slide seen below is an example where every point is mentioned in a single slide.

2. Visual slides

This type of slide has visual elements such as images or videos , and are better known as conceptual slides since they are a better option than text slide to explain a particular concept.

You can use them at the start of the presentation to better visualize and grasp the meaning of the presentation.

The slide right below is a good example of a visual slide.

3. Mixed slides

Mixed slides combine the texts and visuals to give a comprehensive understanding of any concept or a speech.

Graphs and charts are the best examples of mixed slides.

Mixed slides have an advantage over the other slides; they keep your audience engaged, listening and participating more actively!

Types of Oral presentations

So far we came across 6 types of presentations, and they all share one common feature. They are all one of the types of oral presentations.

Oral presentations involve the use of verbal and non-verbal elements to deliver a speech to a particular or general audience.

All the types we discussed fall into these 4 broad categories:

1. Extemporaneous presentations

This type of presentation involves making short pointers or key phrases to aid while speaking.

You do not memorize, but organize the points and structure the speech way in advance.

Hence, on the day of your presentation, by just looking at the key points , you expand on them and move to the next point.

2. Impromptu presentations

Impromptu presentations are spoken without any preparation . It can be nerve-wracking for many, and hence not many are in favor of it.

There is a valid reason for their fear, as you have to make your speech as you say it!

However, those who are experts in their fields and are called upon to share a few words can easily give this type of presentation.

3. Manuscript presentations

The other extreme of the spectrum is manuscript presentations.

Here you have a script and you speak from it, word by word.

News anchors and show announcers usually engage in this type, since there are a lot of specific details that cannot be said wrong, and also, time constraints.

Usually, a prompter is used, from which the speaker speaks to their audience.

Nowadays, there are teleprompters , that are heavily used in the entertainment and media industry.

It is a digital screen that displays the contents, and the speaker speaks from it.

4. Memorized presentations

This type does not have any notes or cues , but you memorize or rote learn the whole speech.

School and some presentations at the workplace involve using this kind of presentation.

In most cases, we recommend not to memorise your speech in most cases. We’ve made a video on the same and how it could lead to you potentially blanking out on stage. Highly recommend you view this quick vid before choosing memorisation as a presentation path:

But, if you do choose it for whatever reason, since you are free from notes, you are free to focus on other aspects, such as body language and gestures.

Types of presentation styles

There are various presenting styles, but they do not work for all types of presentations.

Let us get familiar with them, and know which style works with which type.

a) The storyteller

This style of presentation involves the speaker narrating stories and engaging the audience emotionally .

This technique works best with persuasive and inspirational types of presentation.

So, how to tell a story in a presentation?

• Understand and know your audience : Knowing your audience will help you with how you will frame your story, at the same time gauging the relevance of your narrative
• Know your message : Be clear with what you want to convey through your story or how you are connecting the story with your actual presentation
• Try narrative a real-life story : Inspiring presenters often take their own stories or the stories of people whom they know as a supplement to their presentation. When the audience listens to your real-life examples, they become genuinely interested in your story
• Add visual aids : Using visual aids such as pictures, videos, multimedia, etc., increases the memory retention and engagement of your audience
• Use the “you” attitude : Tell the story keeping your audience in mind because ultimately they are going to be the receivers and hence, the story should be relevant and should include their point of view as well

Want more storytelling tactics? Mystery, characterisation and the final takeaway are some more key elements of a good story for your next presentation. We’ve gone deeper into this topic in this video if you would like to know more:

b) The Visual style

Most of us are visual learners, making visual information easy to understand and retain.

Visual aids like graphics, images, diagrams, key pointers or phrases , etc., are very useful when giving any type of presentation.

Some tips of presenting with visual style:

• Include only important pointers in your PowerPoint presentation and highlight or bold them
• Try including visuals that complement what you are saying and use them as a supplementary tool to aid in understanding your audience
• If you are giving a business presentation and want to include visuals, instead of plain texts, include graphics and charts to make information simpler to present and understand
• Avoid overly complex visuals as it will confuse the audience more
• Avoid using more than 6 lines per slide

c) Analytic style

If you have data records or statistical information to be presented, an analytic style will be more helpful.

It works best for Informative and Business types of presentations.

Tips to deliver in analytic style:

• Give handouts so that the audience is on track with your presentation and the information will be easier to comprehend
• Focus and speak on selected data as too much data statistics can be overwhelming for the audience
• You can make use of humor and personal anecdotes to keep the presentation interesting and engaging
• If you have too much data and are worried that you will not be able to explain it in the time frame given, avoid writing content of more than 2000 words

Quick tip: In case you have a PDF to present and want to edit the data points, there are multiple software programs that you can use to allow you to easily do this. Check out this list of the Best Free Recording Software Programs to know more.

d) The Connector

The connector style of presentation involves the speaker establishing a connection with the audience by pointing out similarities between them and the listeners.

This style works well with Sales and marketing presentations.

How to give a presentation using connector style?

• Have a Q & A round with the audience at the end of your presentation for clarifying any doubts and avoiding miscommunication
• Use audience polls at the start of your presentation to know your audience and tailor your speech accordingly
• Make use of body language and gestures for delivering your presentation effectively. If you are confused or want to know more about the aspects of how to use body and gestures, check out our article on To walk or stand still: How should you present when on stage?
• Ask questions to your audience at regular intervals for a better audience engagement
• Make use of multimedia sources to keep your audience engaged and entertained

Which type of presentation is best?

Although all the presentation types have their own bonuses and are suitable for certain circumstances, some are universal and can be used with a little bit of modification almost everywhere!

These are persuasive presentations!

You can use them in various settings; from political, business to educational.

Just remember to choose the right topic for the right audience, and a style that you think is the most suitable and you are good to go!

Despite the prevalence of PowerPoint in professional and educational presentations, surprisingly little is known about how effective such presentations are. All else being equal, are PowerPoint presentations better than purely oral presentations or those that use alternative software tools? To address this question we recreated a real-world business scenario in which individuals presented to a corporate board. Participants (playing the role of the presenter) were randomly assigned to create PowerPoint, Prezi, or oral presentations, and then actually delivered the presentation live to other participants (playing the role of corporate executives). Across two experiments and on a variety of dimensions, participants evaluated PowerPoint presentations comparably to oral presentations, but evaluated Prezi presentations more favorably than both PowerPoint and oral presentations. There was some evidence that participants who viewed different types of presentations came to different conclusions about the business scenario, but no evidence that they remembered or comprehended the scenario differently. We conclude that the observed effects of presentation format are not merely the result of novelty, bias, experimenter-, or software-specific characteristics, but instead reveal a communication preference for using the panning-and-zooming animations that characterize Prezi presentations.

Introduction

How do the characteristics of a communication medium affect its messages? This question has been the subject of much philosophical and empirical inquiry, with some (e.g., [ 1 ]) claiming that the medium determines the message (“the medium is the message”), others (e.g., [ 2 ]) claiming that characteristics of a medium affect the message, and others claiming that the medium and message are separable (e.g.,[ 3 , 4 ]). As psychologists, we ask: What mental mechanisms underlie effective communication and how can presenters leverage these mechanisms to communicate better? These questions—at the intersection of psychology and communication practice—motivate this research.

That said, the relative efficacy of different communication media or technologies informs the primary questions of interest. If we can demonstrate that oral presentations are less or more effective than those that rely on presentation software—or that presenters who use one type of presentation software tend to be more effective than those who use another—then we advance our psychological and practical understanding of effective communication. Thus, in the tradition of use-inspired basic research [ 5 ]—and as a means to an end, rather than an end unto itself—we compare the effectiveness of three commonly-used formats for communication: oral, PowerPoint, and Prezi presentations.

We focused on presentations because they populate our academic, professional, and even personal lives in the form of public speeches, academic lectures, webinars, class presentations, wedding toasts, courtroom arguments, sermons, product demonstrations, and business presentations [ 6 – 8 ], and because basic questions remain about how to present effectively. Should we present with or without presentation software? If we should present with software, which software? We examined PowerPoint and Prezi because they are popular and psychologically interesting alternatives: Whereas PowerPoint’s linear slide format might reduce cognitive load, focus attention, and promote logical analysis, Prezi’s map-like canvas format and heavy reliance on animation (see the Background section and https://prezi.com for examples) might facilitate visuospatial processing, conceptual understanding, and narrative storytelling.

To inform the present research, we explore the methodological challenges of media research and review past research on presentation formats.

Methodological challenges of media research

To research the efficacy of different communication formats fairly and accurately, one must overcome two stubborn methodological challenges. First, because correlation is not causation and the variables that underlie media usage are heavily confounded, such research requires true experimentation. To study whether a blended learning “flipped classroom” is a more effective instructional medium than traditional lecturing, for example, researchers gain little insight by comparing outcomes for students who enroll in one type of course versus the other. To control for audience (in this case, student) self-selection effects, researchers need to 1) randomly assign audience members to different communication conditions (in this case, pedagogies) or 2) manipulate format within participants. Moreover, the same methodological controls need to be applied to presenters (in this case, instructors). Instructors who choose to teach with emerging, innovative methods probably differ in numerous other respects (e.g., motivation) from those who teach with more traditional methods. If students assigned randomly to a flipped classroom format perform better than those assigned randomly to a traditional classroom format, we risk drawing inferences about confounds instead of causes unless instructors are also assigned randomly to instructional media. To make strong, accurate inferences, therefore, researchers interested in communication must control for audience and presenter self-selection effects. Such control introduces new complexities; when randomly assigning presenters to formats, for example, one must ensure that all presenters receive sufficient training in the relevant format. Moreover, such control is often cumbersome, sometimes impractical, and occasionally unethical (e.g., randomly assigning students in actual courses to hypothetically worse instructional conditions). But there are no adequate methodological substitutes for proper experimental control.

A second thorny methodological challenge inherent in conducting media research concerns how to draw general inferences about formats instead of specific inferences about exemplars of those formats. For example, if one advertising expert is assigned randomly to design a print ad and another expert a television ad—and a hundred consumers are assigned randomly to view the television or print ad—can we actually infer anything about print versus television ads in general when the two groups of consumers behave differently? Arguably not, because such a finding is just as easily explained by other (confounding) differences between the ads or their creators (e.g., ratio of print to graphics, which sorts of people—if any—are shown, and so forth). In other words, even with proper random assignment, researchers who intend to study different forms of communication risk merely studying different instances of communication. Statistically speaking, one should assume a random not fixed effect of the communication objects of interest (e.g., presentations, lectures, advertisements). To overcome this challenge and draw generalizable inferences, one must (at the very least) sample a sufficiently large set of examples within each medium.

Research on presentation software

Methodological shortcomings..

Considerable research has been conducted on how different presentation formats (particularly PowerPoint) convey information (for review, see [ 9 ]). However, much of this research is anecdotal or based on case studies. For example, Tufte [ 10 ] claims that PowerPoint’s default settings lead presenters to create bulleted lists and vacuous graphs that abbreviate arguments and fragment thought. And Kjeldsen [ 11 ] used Al Gore’s TED talk on climate change as a positive example of how visuals can be used to effectively convey evidence and enhance verbal communication.

Research that goes beyond mere anecdote or case study is plagued by the aforementioned methodological shortcomings: failure to control for audience self-selection effects (71% of studies), failure to control for presenter self-selection effects (100% of studies), and a problematic assumption of fixed effects across content and presenters (91% of studies). As is evident in Table 1 , no studies overcame two of these shortcomings, let alone all three. For example, in one of the most heavily-cited publications on this topic Szabo and Hasting [ 12 ] investigated the efficacy of PowerPoint in undergraduate education. In the first study, they examined whether students who received lectures with PowerPoint performed better on a test than students who received traditional lectures. Students were not assigned randomly to lecture conditions, however; rather, the comparison was across time, between two cohorts of students enrolled in different iterations of the same course. Any observed outcome difference could have been caused by student or instructor variables (e.g., preparedness), not lecture format. The fact that no such differences were found does not obviate this concern: Such differences may in fact have been present, but were overshadowed by confounding characteristics of students or instructors. In the second study, the authors varied presentation format within the same cohort of students, but confounded format with order, time, content, and performance measure: student performance was compared between lectures on different days, on different topics, and using different tests. As the authors themselves note, the observed differences may have had nothing to do with PowerPoint. In the third study, they counterbalanced lecture order and content; some students received a PowerPoint lecture first and others a traditional lecture first, and the same topics were presented in both formats. However, students were assigned to conditions based on their course enrollment, not randomly, but more importantly the study included only four presentations, all by one presenter. Any advantages of the two PowerPoint lectures (none were found) might have been particular to those instances or that presenter and not representative of the format more generally.

Most studies—even those that control experimentally for audience self-selection—relied on only a single self-selected presenter, and some relied on only one presentation per format. In one study ([ 13 ]: Experiment 1), for example, one of the authors varied the format of his lecture instruction randomly across the semester, using transparences or PowerPoint slides. In another study [ 14 ], students who were enrolled in one of the authors’ courses were assigned randomly to a PowerPoint or Prezi e-lecture that contained identical audio narration and written text. In a third study [ 15 ], one of the researchers gave the same lecture over the course of the year to rotating medical students, using PowerPoint on odd months and overhead slides on even months. What reason is there to think that we can make general claims about presentation format based on studies of single lectures or single presenters? That is, how can we reasonably assume fixed as opposed to random effects? If the use of presentation software does meaningfully influence student learning or experience, surely that effect is not constant across all presenters or presentations—some instructors use it more effectively than others, and within any format some presentations are more effective than others (see [ 16 ]). And how can we assume that presenters who select both the content and format of their presentations are not designing them in ways that favor one format over another?

Research on the efficacy of presentation software has numerous other flaws, most notably the failure to control for experimenter effects or demand characteristics. In 82% of studies we identified, for example, the researchers investigated their own instruction and studied their own students. It is difficult to imagine that one would make these instructional and research efforts (e.g., creating new course material, conducting a field experiment) without a strong belief in the efficacy of one format over the other, and it is plausible (if not likely) that such beliefs would influence students or confound instructional format with instructional effort and enthusiasm.

Another common issue is the confounding of lecture format with access to study materials—in studies that contrast PowerPoint with traditional lecturing (e.g., [ 17 – 19 ]), students in the PowerPoint condition (but not the control condition) sometimes have access to PowerPoint slides as study material. This access could bias student motivation, behavior (e.g., attendance), course satisfaction, and performance (see [ 20 ]).

PowerPoint: Performance, perception, and persuasion.

Despite their methodological shortcomings, what are the findings of this research literature? The majority of studies examined the use of PowerPoint in higher education and measured both objective and subjective outcomes (see Table 1 ). They typically involved students enrolled in one or more of the researchers’ courses, and contrasted the efficacy of lectures (or whole lecture courses) that used PowerPoint with those that used a more traditional technology (e.g., blackboards, overhead projectors). In terms of student performance, their findings were notably mixed: Of the 28 studies we identified, 17 found no effect of PowerPoint lectures relative to traditional lectures ([ 12 ]: Experiments 1,3; [ 13 , 15 , 21 – 33 ]), 9 found a performance benefit of PowerPoint over traditional instruction ([ 12 ]: Experiment 2; [ 17 – 19 , 34 – 38 ]), and 2 found a performance benefit of traditional over PowerPoint instruction [ 39 , 40 ].

There is near consensus in the literature, however, when it comes student perception: Of the 26 studies we identified, 21 found that students preferred PowerPoint over traditional instruction ([ 12 ]: Experiment 1; [ 13 , 17 – 19 , 21 , 23 , 25 , 26 , 28 , 29 , 31 – 33 , 35 , 39 , 41 – 45 ]), 2 found that students preferred traditional over PowerPoint instruction [ 40 , 46 ], and 3 other studies found no preference for one or the other formats [ 15 , 22 , 37 ]. As one example, Tang and Austin [ 45 ] surveyed 215 undergraduates in business courses about their general perceptions of different lecture formats; on measures of enjoyment, learning, motivation, and career relevance, they found that students rated lectures with PowerPoint slides more favorably than lectures with overheads or without visual aids. An additional 7 studies did not contrast student perceptions of PowerPoint with another technology—they simply surveyed students about PowerPoint; these studies all found that students had, on average, favorable impressions of PowerPoint-based instruction [ 36 , 47 – 52 ].

In addition to these studies of how presentation software impacts student performance and perception, two studies examined PowerPoint‘s impact on audience persuasion. Guadagno, Sundie, Hardison, and Cialdini [ 53 ] argue that we heuristically use a presentation’s format to evaluate its content, particularly when we lack the expertise to evaluate the content on its merits. To test this hypothesis, they presented undergraduates with key statistics about a university football recruit and asked them to evaluate the recruit’s career prospects. The same statistics were presented in one of three formats: a written summary, a graphical summary via printed-out PowerPoint slides, or a graphical summary via animated PowerPoint slides (self-advanced by the participant). Participants shown the computer-based PowerPoint presentation tended to rate the recruit more positively than other participants, and there was some evidence that this effect was more pronounced for football novices than for experts. The findings of this study suggest that some presentation formats may be more persuasive than others, perhaps because audience members conflate a sophisticated medium with a sophisticated message.

In the second study to examine the impact of PowerPoint on persuasion, Park and Feigenson [ 54 ] examined the impact of video-recorded presentations on mock juror decision-making. Participants were more persuaded by attorneys on either side of a liability case when the attorney used PowerPoint slides as opposed to merely oral argument. They also remembered more details from PowerPoint than oral presentations, and evaluated both attorneys as more persuasive, competent, credible, and prepared when they presented with PowerPoint. Based on mediation analyses, the researchers argue that the decision-making benefit of PowerPoint results from both deliberative and heuristic processing (“slow” and “fast” thinking, respectively, see [ 55 ]).

Both of these studies, however, share the methodological limitations of the educational research on PowerPoint. The first study [ 53 ] used only one PowerPoint presentation, and the second [ 54 ] used only two. The presentations used were not selected at random from a larger stimulus pool but instead were created by researchers who hypothesized that PowerPoint would enhance presentations. But even if the presentations had been sampled randomly, the sample is too small to allow one to generalize to a broader population. In studying performance, perception, or persuasion, one cannot reasonably assume that all presentation effects are equal.

Prezi: A zoomable user interface.

Released in 2009, Prezi has received generally favorable reviews by researchers, educators, and professional critics [ 56 – 60 ]. With a purported 75 million users worldwide, it is increasingly popular but still an order of magnitude less so than PowerPoint (with as many as one billion users; [ 61 ]). Like PowerPoint and other slideware, Prezi allows users to arrange images, graphics, text, audio, video and animations, and to present them alongside aural narration to an in-person or remote audience. In contrast to PowerPoint and other slideware in which users create presentations as a deck of slides, Prezi users create presentations on a single visuospatial canvas. In this regard, Prezi is much like a blackboard and chalk. But unlike a physical blackboard, the Prezi canvas is infinite (cf. [ 62 ]) and zoomable: in designing presentations, users can infinitely expand the size of their canvas and can zoom in or out. When presenting, users define paths to navigate their audience through the map-like presentation, zooming and panning from a fixed-angle overhead view.

Like Google Maps or modern touchscreens, Prezi is an example of what scholars of human-computer interaction label a zoomable user interface (ZUI). These interfaces are defined by two features: They present information in a theoretically infinite two-dimensional space (i.e., an infinite canvas) and they enable users to animate this virtual space through panning and zooming. Some of the original ZUIs were used to visualize history, navigate file systems, browse images, and—in the Prezi predecessor CounterPoint—create presentations [ 63 , 64 ].

As communication and visualization tools, ZUIs in general and Prezi in particular are interesting psychologically for several reasons. First, they may take advantage of our mental and neural architecture, specifically the fact that we process information through dissociable visual and spatial systems. Whereas the so-called “ventral” visual system in the brain processes information such as shape and color, the “dorsal” spatial system processes information such as location and distance [ 65 – 68 ]. When working in concert, these systems result in vastly better memory and comprehension than when they work in isolation. For example, in the classic “method of loci” individuals visualize objects in specific locations; when later trying to recall the objects, they visualize navigating through the space, “seeing” each object in turn. This method typically doubles retention, compared to other ways of trying to memorize objects [ 69 , 70 ]. Similarly, in research on note-taking, students learned more when they used spatial methods than when they used linear methods (e.g., [ 71 ]). Mayer’s multimedia learning principles and evidence in their favor also highlight the importance of spatial contiguity [ 72 ].

Thus, by encouraging users to visualize and process information spatially, ZUIs such as Prezi may confer an advantage over traditional tools such as PowerPoint that do not encourage such visuospatial integration. As Good and Bederson [ 64 ] write: “Because they employ a metaphor based on physical space and navigation, ZUIs offer an additional avenue for exploring the utilization of human spatial abilities during a presentation.”

Furthermore, ZUIs may encourage a particularly efficacious type of spatial processing, namely graphical processing. In graphical processing, digital objects (or groups of objects) are not just arranged in space, they are arranged or connected in a way makes their interrelationships explicit. Randomly placing animal stickers on a blank page, for example, engages mere spatial processing; drawing connecting lines between animals of the same genus or arranging the animals into a phylogenetic tree, however, engages graphical processing. Because ZUIs force users to “see the big picture,” they may prompt deeper processing than software that segments content into separate spatial canvases. By facilitating such processing, ZUIs may leverage the same learning benefits of concept maps and other graphical organizers, which have been studied extensively. For example, in their meta-analysis of the use of concept maps in education, Nesbit and Adesope [ 73 ] found that these graphical representations (especially when animated) were more effective than texts, lists, and outlines. By requiring one to organize the whole presentation on a single canvas instead of a slide deck, therefore, Prezi may prompt presenters (and their audiences) to connect component ideas with each other, contextualize them in a larger narrative, and remember, understand, and appreciate this larger narrative. Slideware, on the other hand, may do just the opposite:

PowerPoint favours information that can be displayed on a single projected 4:3 rectangle. Knowledge that requires more space is disadvantaged … How to include a story on a slide? Distributing the associated text over several slides literally breaks it into fragments, disturbing its natural cohesion and thus coherence … PowerPoint renders obsolete some complex narrative and data forms in favour of those that are easily abbreviated or otherwise lend themselves to display on a series of slides [ 74 ] (p399)

Of course these arguments are speculative, and one can also speculate on the psychological costs of ZUI or benefits of standard slideware. Perhaps PowerPoint does confer some of same spatial processing benefits of Prezi—after all, slides are spatial canvases, and they must be arranged to form a narrative—but in a way that better manages the limited attentional resources of the presenter or audience. Our point here is simply that Prezi, as a ZUI presentation tool, offers a psychologically interesting alternative to standard deck-based slideware, with a range of possible advantages that could be explored empirically to discover the psychological mechanisms of effective communication.

Like the PowerPoint literature, most of the published literature on Prezi is limited to observational reports or case studies. Brock and Brodahl [ 75 ] evaluated Prezi favorably based on their review and students’ ratings of course presentations. Conboy, Fletcher, Russell, and Wilson [ 76 ] interviewed 6 undergraduates and 3 staff members about their experiences with Prezi in lecture instruction and reported generally positive experiences. Masood and Othman [ 77 ] measured the eye movements and subjective judgments of ten participants who viewed a single Prezi presentation; participants attended to the presentation’s text more than to its other components (e.g., images, headings), and favorably judged the presentation. Ballentine [ 78 ] assigned students to use Prezi to design text adventure games and reported benefits of using the medium. Two other studies [ 79 , 80 ] surveyed college students about their course experiences with Prezi, and both reported similarly positive perceptions.

All of these studies, however, suffer from major demand characteristics, due to the fact that the researchers observed or asked leading questions of their own students about their own instruction (e.g., “Do you find lectures delivered with Prezi more engaging then[sic] other lectures?”, from [ 79 ]). Moreover, all suffer from the methodological limitations discussed earlier.

Other literature that addresses Prezi is purely theoretical and speculative: In discussing the pedagogical implications of various presentation software, Harris [ 81 ] mostly just describes Prezi’s features, but does suggest that some of these features provide useful visual metaphors (e.g., zooming in to demonstrate otherwise hidden realities). Bean [ 82 ] offers a particularly compelling analysis of PowerPoint and Prezi’s histories, user interfaces, and visual metaphors, and argues that Prezi is the optimal tool for presenting certain types of information (e.g., wireflow diagrams).

The experimental literature on Prezi is limited to three published studies. Castelyn, Mottart and Valcke [ 14 ] investigated whether a Prezi e-lecture with graphic organizers (e.g., concepts maps) was more effective than a PowerPoint e-lecture without graphic organizers. Claiming that Prezi encourages the use of graphic organizers, they purposefully confounded the type of presentation software with the presence of graphic organizers. Undergraduates randomly assigned to the different e-lectures did not differ in their knowledge or self-efficacy gains, but did prefer the graphically-organized Prezi lecture over the PowerPoint control lecture. In a follow-up study [ 83 ], the same researchers assigned undergraduates to create Prezi presentations that did or did not use graphic organizers, and found no effects of this manipulation on students’ self-reported motivation or self-efficacy. Chou, Chang, and Lu [ 24 ] compared the effects of Prezi, PowerPoint and traditional blackboard instruction on 5 th graders’ learning of geography. Whereas the Prezi group performed better than the control group (which received blackboard instruction) in formative quizzes and a summative test, the PowerPoint group did not; however, on a delayed summative test, both Prezi and PowerPoint students performed better than those in the control group. In direct comparisons of PowerPoint and Prezi, there were no differences in any of the learning measures. Taken together, the studies are not just limited in number: They present uncompelling findings and suffer from the same methodological shortcomings of the PowerPoint research.

The current study

In short, the extant literature does not clarify whether presenters should present with or without visual aids—and, if the latter, whether they should use standard deck-based slideware such as PowerPoint or a ZUI such as Prezi. One of the reasons why these basic questions remain unanswered is the methodological challenges inherent in comparing different presentation formats. We designed the current study to overcome these challenges.

To control for individual differences among presenters, we randomly assigned presenters to different presentation conditions. To control for individual differences among audience members, we used a counterbalanced, within-participants design for the first experiment, and between-participants random assignment in the second experiment. And to draw general inferences about the impact of presentation format—instead of specific inferences about particular presenters or presentations—we sampled from a large number of presentations, each created by a different presenter. Our methods have their own challenges, such as recruiting participants sufficiently trained in all presentation methods, allowing presenters adequate preparation time and context, approximating the psychological conditions of real-world presentations, and measuring the “signal” of presentation format among the added “noise” of so many presenters and presentations. In addition, the studies had to be double-blind: Neither presenters nor audience members could be aware of any hypotheses, and had to be free from any sorts of confirmation bias conveyed by the investigators.

To focus on presentations as a form of presenter-audience communication and limit the number of confounded variables, we purposefully controlled for other possible impacts of presentation software on professional practices or outcomes, including 1) the use of presentation artifacts (e.g., PowerPoint files, printed-out slides, online Prezis), and 2) facilitated collaboration among presentation designers. Unlike other research (e.g., [ 32 , 33 ]) we did allow for the possibility that presentation format not only affects how audiences perceive presentations, but also how presenters design or deliver them (e.g., by increasing their conceptual understanding of the topic, or decreasing their cognitive load during live narration; cf. [ 84 ]). In other words, presentation technologies might affect the cognition of both the audience and the presenter, so we designed the present studies to accommodate both sets of mechanisms.

To maximize the real-world relevance of this research, we relied on multimedia case materials from Harvard Business School [ 85 ]; these materials recreate the actual professional circumstances in which presentations are typically used. Because presentations are designed commonly both to inform and convince audiences, we examine outcome measures of learning as well as persuasion. And to minimize demand characteristics, we avoided the typical flaws of existing research (e.g., researcher-designed presentations, the researchers’ students as research participants) and adopted several countermeasures (e.g., recruitment language and participant instructions that obscured the research hypotheses, between-participant manipulation).

We adopted a two-phased approach in this research. In the first phase, participants with sufficient experience in oral, PowerPoint, and Prezi presentation formats were randomly assigned to create a presentation in one of those formats. We provided the necessary context, instruction, and time to create a short but realistic presentation. Participants then presented live to an actual audience, who judged each presentation’s efficacy. In the second phase, recorded versions of these presentations were presented to a larger online audience, affording us greater statistical power and allowing us to measure the impact of presentation format on decision-making and learning.

Experiment 1

Participants..

We recruited presenter participants via online postings (on Craigslist, the Harvard Psychology Study Pool, the Harvard Decision Science Lab Study Pool), email solicitations to the local Prezi community, and campus flyers. To create the fairest comparison between PowerPoint and Prezi, we recruited individuals who “have expertise in using both PowerPoint and Prezi presentation software.” Interested individuals were directed to a prescreening survey in which they reported their experience with and preference for giving different types of presentations. Only individuals who reported that they were “not at all experienced” with PowerPoint, Prezi or giving oral presentations were excluded from research participation. Out of the 681 respondents who completed the prescreening survey, 456 of them were eligible and invited to sign up for an available timeslot. Out of this group, 146 individuals—105 from the Harvard study pools, 33 from Craigslist, and 8 from the Prezi community—participated as presenters in the study and were compensated $40 for approximately two hours of their time. There were no significant differences between the three presentation groups on any demographics variables.

We also recruited 153 audience participants from the Harvard Decision Science Lab Study Pool and Craigslist using the following announcement:

Do you use Skype? Does your computer have a large screen (13 inches or larger)? If so, you may be eligible to participate in a 45 minute long online study. In this study, you will watch professional presentations over Skype from home on your personal computer.

Anyone who responded to the recruitment notice was eligible, provided that they were available during one of the prescheduled testing sessions. Audience participants were compensated $10 for approximately 45 minutes of their time. Table 2 presents demographic information for the presenter and audience participants. This study was approved by the Harvard Committee on the Use of Human Subjects (Study #IRB14-1427), and all participants in both experiments provided written consent.

Presenter procedure.

Presenter participants completed a survey remotely before attending the in-person, group sessions with other participants. In the online pre-survey, presenters first answered basic demographic questions (gender, age, education level, English fluency, and occupation). Next, they answered questions about their prior experience with, opinions about, and understanding of the different presentation formats (oral, Prezi, and PowerPoint). This section was prefaced with the following note:

A note on language: When we use the term "presentation," we mean a formal, planned, and oral presentation of any duration, including a public speech, an academic lecture, a webinar, a class presentation, a wedding toast, a sermon, a product demonstration, a business presentation, and so on. Examples of things we do NOT mean are: a theatrical performance, an impromptu toast at dinner, and any presentation with no audience. When we say PowerPoint presentations, we mean presentations that were made using Microsoft PowerPoint, not other software such as Apple's Keynote. When we say Prezi presentations, we mean presentations that were made using Prezi presentation software. Also, when we refer to "oral presentation", we mean a presentation that is only spoken and does not include any visual aids or the use of presentation software.

Participants were asked the following questions for each type of presentation:

• How experienced are you at making the following types of presentations? [5-level rating]
• When you give a presentation, how effective are the following types of presentations for you? [5-level rating, with “not applicable” option]
• When somebody else gives a presentation, how effective are the following types of presentations for you? [5-level rating, with “not applicable” option]
• How difficult is it for you to make the following types of presentations? [5-level rating, with “not applicable” option]
• In the last year, approximately how many of the following types of presentations did you make? [free response]
• In your lifetime, approximately how many of the following types of presentations have you made? [free response]
• For approximately how many years have you been making the following types of presentations? [free response]

As part of the expertise-related measures, we also asked the participants to identify the purported advantages and disadvantages of each presentation format, according to its proponents and critics, respectively. For PowerPoint and Prezi, we asked participants to identify whether or not it had particular functionalities (e.g., the capacity to record narration, create custom backgrounds, print handouts). Finally, participants viewed three sets of four short Prezi presentations and rank-ordered them from best to worst. In each set we manipulated a key dimension of Prezi effectiveness, according to its designers: the use of zooming, the connection of ideas, and the use of visual metaphor.

Presenter participants were tested in person at the Harvard Decision Science Lab, and randomly assigned to one of the three groups: Prezi, PowerPoint, or oral presentation. A total of 50 data collection sessions were held. In each session, there were typically three presenter participants (one for each presentation format); as a result of participants who failed to arrive or overbooking, there were ten sessions with only two presenters and six sessions with four presenters.

After providing informed consent, participants completed an online survey (in the lab) in which they rank-ordered three sets of recorded example PowerPoint and oral presentations. Identical in form to the example Prezi presentations they judged in the pre-survey, these short presentations were designed to assess their understanding of effective presentation design by manipulating a key aspect specific to each format. For PowerPoint presentations, we manipulated the use of text, use of extraneous “bells and whistles,” and graph design; for oral presentations, the three dimensions were verbal behavior, nonverbal behavior (other than eye contact), and eye contact. In selecting these dimensions (and those for Prezi), we consulted with a variety of experts, including software designers, speaking coaches, and researchers.

Next, presenters were shown material from a multimedia case created for and used by the Harvard Business School. Specifically, they were told the following (the company featured in the business case will be referred to anonymously here as “Company X” to respect their contractual agreement with the school):

For the next two hours, you are going to pretend to be the chief marketing officer of i-Mart, a large chain of retail stores. i-Mart recently made an offer to [Company X] to sell their products in i-Mart stores. Your boss, the CEO of i-Mart, has asked you to make a presentation to [Company X]’s leadership that persuades them to accept i-Mart’s offer. In your presentation, you will need to argue that accepting i-Mart’s offer is in [Company X]’s strategic interests, and address any concerns they may have about how accepting the offer might affect their corporate identity.

As a participant in this study, your primary job today is to prepare and then deliver this presentation. The presentation will be very short (less than 5 minutes) and made live (via Skype) to an audience of participants who are playing the part of [Company X] executives. Before you start planning your presentation, you will first learn more about [Company X] and how they’re thinking about i-Mart’s offer.

On their own computer workstation, participants studied the multimedia case for 30 minutes and were invited to take notes on blank paper provided for them. The multimedia case material included video and textual descriptions of Company’s X’s corporate culture, business model, and constituent communities.

Following this study period, participants were given 45 minutes to create a presentation in one of three randomly assigned presentation formats: PowerPoint, Prezi, or oral. To assist participants in the PowerPoint and Prezi conditions, we provided them with a set of digital artifacts including text, data, and graphics related to the case. Participants were not told that other participants were asked to present in different formats, and the workstations were separated from each other to prevent participants from discovering this manipulation.

After this preparation period, participants were taken individually (in a counterbalanced order) to another room to present to a live audience via Skype. For PowerPoint and Prezi presentations, we shared each participant’s presentation with the audience via screen sharing; thus they viewed both the presenter and the presentation. For those presenters who consented, we also recorded their presentations for future research purposes. After making their presentations, presenters completed a final survey about their presentation (e.g., “How convincing do you think your presentation will be to [Company X’s] board members”), the corporate scenario (e.g., What do you think [Company X] should do?”), and their presentation format (e.g., “How likely are you to recommend the presentation tool or presentation format you used to others to make professional presentations?”).

Audience procedure.

Audience participants completed the entire experiment remotely and online. Their participation was scheduled for the end of the presenter sessions so that the in-lab presenters could present live to a remote audience via Skype. We recruited between three and six audience participants per session, although participants who failed to arrive or Skype connectivity issues resulted in some sessions with only one or two audience participants: Five sessions had one participant, twelve sessions had two participants, sixteen sessions had three participants, eleven sessions had four participants, four sessions had five participants, and two sessions had six participants.

Individuals who responded to the recruitment notice completed a consent form and three online surveys prior to their scheduled Skype session. The first survey was a slightly modified form of the presenter pre-survey (demographics, background on presentation formats, rank-ordering of example Prezis) in which they also scheduled their Skype session. In the second survey, audience participants were told that they were “going to play the role of a corporate executive listening to several short business presentations,” and that their task was “to evaluate the quality of these presentations, each made by another participant engaged in a similar role-playing scenario.” They were then shown a brief video and textual description of the fictionalized corporate scenario (an abridged version of what presenter participants studied), and told the following:

You are a board member for [Company X], an innovative clothing company. Another company, i-Mart, wants to sell [Company Y’s products] in its stores. You and your fellow board members must decide whether or not to accept i-Mart's offer.

And in the third survey they rank-ordered the three sets of recorded example PowerPoint and oral presentations.

At the time of the scheduled session, the audience participants logged into Skype using a generic account provided by the research team, and were instructed to turn on their webcams and put on headphones. Once the first presenter participant was ready to present, the experimenter initiated the group Skype call, confirmed that the software was functioning properly, invited the presenter into the room to begin, left the room before the start of the presentation, monitored the presentation remotely via a closed-circuit video feed, and re-entered the room at the presentation’s conclusion. For Prezi and PowerPoint presentations, Skype’s built-in screen-sharing function was used to share the visual component of the presentation; audience participants viewing these presentations were instructed to use the split-screen view, with windows of equal size showing the presenter and the accompanying visuals.

Immediately after viewing each presentation, participants evaluated it via an online survey. They rated each presentation on how organized, engaging, realistic, persuasive, and effective it was using a five-level scale with response options of not at all , slightly , somewhat , very , and extremely . They were also invited to offer feedback to the presenter on how the presentation could be improved. After the final presentation, participants rank-ordered the presentations on the same dimensions (e.g., effectiveness, persuasiveness). Halfway through the experiment we added a final question in which we asked participants to rank-order PowerPoint, Prezi, and oral presentation formats “in terms of their general effectiveness, ignoring how well individual presenters (including today's) use that format,” and to explain their rank-ordering.

Prior experience and pre-existing beliefs.

Participants’ prior experience with and pre-existing beliefs about each presentation format provide a baseline that informs the research findings. If presenter participants had more experience with and more positive beliefs about one format than the others—and those assigned to that format induced more positive assessments from the audience members than did those assigned to the other formats—then the results are less compelling than if there was no correlation between these baseline measures and the experimental outcomes. The same applies to audience participants: Are they merely judging presentations according to their initial biases? Conversely, the results are most compelling if there is a negative association between the baseline measures and the experimental findings. For this reason—and to check that presenters assigned to the different formats did not happen to differ in these baseline measures—we analyzed participants’ prior experience with and pre-existing beliefs about PowerPoint, Prezi, and oral presentation formats.

Both audience and presenter participants were least experienced with Prezi and most experienced with oral presentations. At the outset, they rated PowerPoint as the most effective and easiest to use to present material and Prezi as the least effective and most difficult to use to present. For watching presentations, audience participants rated PowerPoint most effective and oral presentations least effective, but rated Prezi as more enjoyable than other formats. For watching presentations, presenter participants did not find any format more effective than the others. Table 3 presents full descriptive and inferential statistics for all self-reported measures of prior experience with and preexisting beliefs about Prezi, PowerPoint, and oral presentations.

https://doi.org/10.1371/journal.pone.0178774.t003

Presenters assigned to different formats did not differ in their experience with or pre-existing beliefs about presentations formats. They also did not differ in how well they identified the purported advantages and disadvantages of each presentation format, how well they identified the software features of PowerPoint and Prezi, or how accurately they could identify effective presentations of each format.

Audience ratings.

In term of their prior experience with and pre-existing beliefs about presentation formats, both audience and presenter participants were biased in favor of oral and PowerPoint presentations and against Prezi. After presenters were randomly assigned to these different formats, how did the audience evaluate their presentations?

In examining how presentation format affected the audience’s ratings of the presentations, two complications arose. First, sessions with two presentations were missing one presentation format, and sessions with four presentations had two presentations of the same format. To address this complexity we only conducted pairwise comparisons of different formats (e.g., PPT versus oral) instead of omnibus tests, and—for those sessions with four presentations—we averaged ratings for the two same-format presentations. To be certain that the differing number of presentations per session did not somehow bias the results even after adopting these measures, we also conducted an analysis on the subset of sessions that had exactly three presentations.

Second, the number of audience participants per session ranged from one to six. In calculating descriptive statistics, some sessions would be weighted more heavily than others unless ratings were first averaged across participants within the same session, then averaged across sessions. In calculating inferential statistics, averaging across ratings from different participants within the same session who received presentations in the same format was necessary to ensure that the sampling units were independent of each other, an assumption of all parametric and most nonparametric tests. In other words, for both descriptive and inferential statistics, we treated session (instead of participant) as the sampling unit.

As an empirical matter, this multi-step averaging—within participants across identical presentation formats, then across participants within the same session—had little impact on the condition means (i.e., the average ratings of PowerPoint, Prezi, or oral presentations on each dimension). Compared to the simplest, raw averaging of all ratings in one step, the maximum absolute difference between these two sets of means was .07 (on a 1–5 scale) and the mean absolute difference was .04.

To test whether the presentations’ format affected their ratings, therefore, we conducted paired t -tests for each rating dimension, with presentation format as the repeated measure and mean session rating as the dependent variable. Because we conducted three tests for each dimension—pairing each format with every other—we controlled for multiple comparisons by dividing our significance threshold by the same factor (i.e., α = .05/3 = .017). Results revealed that presentation format influenced audience ratings. In particular, the audience rated Prezi presentations as significantly more organized, engaging, persuasive, and effective than both PowerPoint and oral presentations; on a five-level scale, the average participant rated Prezi presentations over half a level higher than other presentations. The audience did not rate PowerPoint presentations differently than oral presentations on any dimension. Table 4 and Fig 1 present these results.

https://doi.org/10.1371/journal.pone.0178774.t004

Audience members rated presentations on each dimension on a 5-level scale (1 = “not at all,” 5 = “extremely”). The figure shows session-level means from all available data, including those from sessions with two or four presentations.

https://doi.org/10.1371/journal.pone.0178774.g001

By limiting the analysis to the 34 sessions with exactly three presentations (one of each format), we could ensure that the sessions with two or four presentations did not somehow bias the results. Moreover, this procedure enabled us to conduct omnibus tests of presentation format for each rating dimension. These omnibus tests revealed significant effects for organization, F (2,66) = 12.9, p < .0001, engagement, F (2,66) = 4.6, p = .01, persuasion, F (2,66) = 3.9, p = .03, and effectiveness, F (2,66) = 7.2, p = .001. The results from post-hoc tests (Fisher’s LSD) aligned with the original pairwise comparisons: On all dimensions, the audience rated Prezi presentations higher than PowerPoint and oral presentations, p s < .05; PowerPoint and oral presentations were not rated differently on any dimension, p s>.05. (Note: All p -values for pairwise tests here and elsewhere are two-tailed.)

To explore whether the obtained results were somehow the result of demand characteristics, we analyzed ratings from only the first presentation in each session. This analysis yielded the same pattern of findings, with a to-be-expected reduction in statistical significance due to the loss of power. On all four dimensions, a one-way, independent-measures ANOVA yielded significant or marginally-significant results: organized, F (2,49) = 5.1, p = .01; engaging, F (2,49) = 2.5, p = .09; persuasive, F (2,49) = 2.6, p = .09; and effective, F (2,49) = 5.8, p = .006. In all cases, Prezi was rated higher than oral and PowerPoint presentations (post-hoc LSD p s ≤.08).

On average, the audience rated the presentations as realistic, with a modal rating of “very realistic.” Our intent in including this rating dimension was merely to verify that our experimental protocol resulted in realistic rather than contrived presentations; we therefore did not test for differences in these ratings as a function of group differences.

Audience rankings.

As just noted, participants randomly assigned to present using Prezi were rated as giving more organized, engaging, persuasive, and effective presentations compared to those randomly assigned to the PowerPoint or oral presentation conditions. In addition, at the end of each session audience participants rank-ordered each type of presentation on the same dimensions used for the ratings. Here we ask: Did the audiences’ rank-orderings align with the ratings?

The same complexities with the ratings data—the variable number of conditions and audience participants per session—applied as well to the ranking data. We therefore adopted a similar analytic strategy, with one exception: we conducted non-parametric rather than parametric pairwise tests, given the rank-ordered nature of the raw data and distributional assumptions that underlie parametric tests.

Using the session-level mean ranks, we tested the effect of presentation format with three sets of Wilcoxon signed-rank tests. The results had the identical pattern as those from the ratings data: the audience rated Prezi presentations as significantly more organized, engaging, persuasive, and effective than both PowerPoint and oral presentation (all p s ≤ .006); the audience did not rate PowerPoint presentations differently than oral presentations on any dimension. Table 5 and Fig 2 present these results.

https://doi.org/10.1371/journal.pone.0178774.t005

Audience members ranked the presentations from best to worst, with lower ranks indicating better presentations. The figure shows session-level means from all available data, including those from sessions with two or four presentations.

https://doi.org/10.1371/journal.pone.0178774.g002

As with the ratings data, we also conducted omnibus tests of only those sessions with exactly three presentations to validate that unbalanced sessions did not somehow bias the results. These tests (Friedman ANOVAs) revealed significant effects for organization, exact p = .0005, engagement, exact p = .04, and effectiveness, exact p = .003; we found only a marginally significant effect for persuasion, exact p = .08. Post-hoc tests (Fisher’s LSD) showed that the audience ranked Prezi presentations higher than PowerPoint and oral presentations on all dimensions, p s < .05; PowerPoint and oral presentations were not ranked differently on engagement, persuasion, or effectiveness, p s>.05, but the audience did rank PowerPoint presentations as more organized than oral presentations, p = .04.

Audience omnibus judgments of effectiveness.

Before and after the experimental session, audience participants judged the general effectiveness of the three presentation formats. In the pre-survey, they rated each format on its effectiveness for them as presenters and audience members. In the post-survey, they rank-ordered the formats on their “general effectiveness” and were instructed to ignore “how well individual presenters (including today's) use that format.” Although the pre- and post-questions differed in their phrasing and response formats, they nonetheless afford us an opportunity to investigate if and how their judgments changed over the course of the experiment.

As already described (see Table 3 ), the audience began the experiment judging PowerPoint presentations as most effective for presenters and audiences. They ended the experiment, however, with different judgments of efficacy: A majority (52%) ranked Prezi presentations as the most effective, a majority (57%) ranked oral presentations as least effective, and a plurality (49%) ranked PowerPoint presentations second in effectiveness. A Friedman’s ANOVA test (on the mean rankings) confirmed that participants rated presentation formats differently, exact p = .00007. Post hoc analysis with Wilcoxon signed-rank tests revealed that the audience ranked both Prezi and PowerPoint presentations as more effective than oral presentations, ps ≤.003). They did not rank Prezi and PowerPoint presentations significantly differently ( p = .15). Fig 3 presents these results.

Note: Means shown from pre-survey items are calculated based on responses from all participants (as opposed to only those who had experience with all presentation formats).

https://doi.org/10.1371/journal.pone.0178774.g003

In the pre-survey, some audience participants reported prior experience viewing Prezi presentations but others did not (i.e., those who selected the “not applicable” response option). Compared to participants with no prior experience watching Prezi presentations ( n = 34), participants with prior Prezi experience ( n = 117) rated PowerPoint presentations (but not oral presentations) as less effective, t (149) = 2.7, p = .007, mean difference = .47, and less enjoyable for them, t (149) = 2.9, p = .004, mean difference = .53. Thus, prior experience with Prezi was associated with negative pre-existing judgments of PowerPoint.

Audience correlates of presentation ratings and rankings.

What, if any, individual-level variables—demographics and baseline survey responses—correlated with the audience’s judgments of the presentations? If, for example, the more experience the audience had with Prezi, the worse they evaluated those presentations, such a correlation would suggest that the current findings reflect a novelty effect.

We did not find any significant relationships between the audiences’ prior experience with a given presentation format (presenter experience rating, number of years, number of presentations watched last year or lifetime) and their ratings or rank-orderings of that presentation format on any dimensions, all | r| s < .16. The only pre-existing audience beliefs about the presentation formats (presenter effectiveness, presenter difficulty, audience effectiveness, audience enjoyableness) that correlated with their ratings or rankings were for oral presentations: the more effective participants rated oral presentations for them as audience members before the experiment, the more effective they rated and ranked oral presentations in the experiment as engaging, r = .22 and .26, respectively, p s < .01.

Among demographic variables, only age showed reliable correlations with the audiences’ evaluations of presentations: the older the participant, the more effective they rated PowerPoint presentations, r = .23, p = .007, the more persuasive they ranked PowerPoint presentations, r = .24, p = .006, and the less organized and persuasive they rated oral presentations, r = -.32, p = .001, and r = -.21, p = .01, respectively.

Audience participants’ success in distinguishing better from worse presentations of each format (i.e., their rank-ordering of short expert-created examples) did not correlate with their evaluations of the experimental presentations, nor did it correlate with the audiences’ self-reported experience with each format.

Audience free response.

Although we cannot assume that participants understood the reasons behind their rank-orderings (cf. [ 86 ]), their explanations may nonetheless offer some insight into how they perceived different presentation formats. In explaining their rank-ordering of the presentation formats in terms of their general effectiveness, 8% of participants who preferred Prezi mentioned that it was new or different or that PowerPoint presentations were old or outdated . More commonly, they described Prezi as more engaging or interactive (49%), organized (18%), visually interesting , visually compelling , visually pleasing , sleek , or vivid (15%), or creative (13%). Of participants who preferred PowerPoint, 38% described it as more concise , clear , easy to follow , familiar , professional , or organized than the other presentation formats. An equal percentage explained their choice in terms of negative judgments of Prezi, including comments that Prezi was disorienting , busy , crowded , amateurish , or overwhelming . Participants who rank-ordered oral presentations as most effective remarked that they felt more engaged or connected with the presenter, could better give their undivided attention to the presentation (29%), valued the eye contact or face-to-face interaction with the presenter (14%), or found presentation software distracting (14%).

Presenter outcomes and correlates of success.

A series of one-way ANOVAs revealed that presentation format did not affect the presenters’ judgments about the business scenario (e.g., “What do you think [Company X] should do?”), self-reported comprehension of the business scenario (“How much do you think you understand the situation with [Company X] and i-Mart?”), or ratings of their own motivation (e.g., “This activity was fun to do”), self-efficacy (e.g., “I think I am pretty good at this activity”), effort (e.g., “I tried very hard on this activity), and effectiveness as presenters (“How convincing do you think your presentation will be to [Company X]’s board members?”); participants using different presentation formats also did not differ in their performance on the multiple-choice test about the business scenario, all p s >.05.

The presenter groups did differ in how inclined they were to recommend their presentation format to others (“How likely are you to recommend the presentation tool or presentation format you used to others to make professional presentations?”), F (2,144) = 4.2, p = .02, with presenters who used Prezi or PowerPoint being more likely to recommend their format than those who made oral presentations, LSD p = .03 and p = .007, respectively.

Presenter variables—including demographic characteristics and experience with their assigned format—generally did not predict their presentation success, either in terms of audience ratings or rankings. The one exception was that Prezi presenters who were better able to identify effective Prezi presentations were rated and ranked as giving more effective and engaging presentations, .008 < p s < .04.

Participants who were randomly assigned to present using Prezi were judged as giving more effective, organized, engaging, and persuasive presentations than those who were randomly assigned to present orally or with PowerPoint. This was true despite the fact that both audience and presenter participants were initially predisposed against Prezi. What might explain these findings?

One explanation is a novelty effect: Perhaps the audience preferred Prezi simply because it is relatively new to them. It appears that this was not the case, however: Only 8% of participants claimed that they preferred Prezi because it was new or different, and there was no significant relationship between the audiences’ experience with Prezi and their ratings or rank-orderings.

Another explanation for these results is that the presenters or audience members were somehow biased towards the Prezi presentations. Again, however, this appears not to be the case. The presenters were least experienced in Prezi, judged themselves least effective presenting with Prezi, and found Prezi presentations hardest to create. We recruited only a small minority (8%) of presenters based on their prior association with Prezi, and used the most conservative exclusion criteria feasible: only individuals without any experience with Prezi or PowerPoint were excluded from participating. All presenters were randomly assigned to their presentation format and were blind to the experimental manipulation. In recruiting audience participants, we did not mention Prezi or PowerPoint, and selected participants only based on their access to Skype and a sufficiently large computer screen. In addition, we minimized contact between the investigator and research participants, and presentations were never identified based on their format; at the end of the experiment, in fact, some participants did not even realize that they had seen a Prezi presentation (as evidenced by their free responses). Data were collected through standardized, online surveys, the investigator was not in the room with the presenter during his or her presentation, and the investigator interacted with the audience only briefly to set up their Skype session. Finally, an analysis of ratings from only the first presentations yielded the same results as the full analysis, making implausible an interpretation based on audience demand characteristics.

Thus, the most likely explanation is that individuals do, in fact, perceive Prezi presentations more favorably than PowerPoint or oral presentation. Experiment 1 has several limitations, however. First, because each audience participant in Experiment 1 was exposed to multiple presentations, we were unable to evaluate presentations on their ultimate goal: to convince the audience (role-playing Company X board members) to accept i-Mart’s business offer. In other words, Experiment 1 demonstrated that Prezi presentations are more effective than other formats in terms of audience perceptions but not decision-making outcomes. Second, we asked the audience about their pre-existing beliefs and prior experiences with PowerPoint, Prezi, and oral presentations at the beginning of the Experiment 1; although it is difficult to imagine how this questioning could have produced the obtained results—particularly given the nature of their pre-existing beliefs and prior experiments—it is a remote possibility. Third, just like the results from any single experiment, the findings of Experiment 1 should be treated cautiously until replicated. We designed a second experiment to address these limitations and extend the findings from the first experiment.

Experiment 2

In Experiment 2 we showed online participants a single presentation from Experiment 1, and varied randomly which type of presentation (Prezi, PowerPoint, or oral) they viewed. We also randomly assigned some participants to view a presentation on material that was not related to the case material; this control condition served as a baseline that allowed us to estimate the impact of each presentation format. To minimize demand characteristics, we asked participants about their experiences with different presentation formats at the conclusion of the experiment (instead of the beginning), and did not expose participants to multiple presentation formats. Finally, to investigate better the nature of participants’ perceptions about presentation effectiveness, we distinguished between perceptions about the presentation, the presenter, and the audiovisual component of the presentation.

We recruited native-English speaking participants via Amazon’s Mechanical Turk using the following language: “In this study, you will read a business case, watch presentations, assume a role, and make a decision.” They were compensated $4 for approximately one hour of their time. Excluding pilot participants who offered us initial feedback on the survey and protocol, 1398 individuals consented to and began the experiment. Of these, 16 participants were excluded because of evidence that they didn’t complete the task properly (e.g., answering a long series of questions identically, incorrectly answering a “trap” question), and 305 were excluded because they dropped out before completing all of the outcome measures, leaving 1069 participants in the final dataset: 272 in the Prezi group, 261 in the PowerPoint group, 275 in the oral presentation group, and 261 in the control group. The number of excluded participants did not covary with group assignment or demographic variables. Table 6 presents demographic information on the included participants.

https://doi.org/10.1371/journal.pone.0178774.t006

The main stimuli for this experiment consisted of recorded presentations from Experiment 1. For Prezi and PowerPoint presentations, these were split-screen videos showing the presenter on one side of the screen and the visuals on the other side. For the oral presentations, these were simply audiovisual recordings of the presenter.

Of the 146 presenter participants from Experiment 1, 33 either did not consent to being video-recorded or were not recorded due to technical difficulties. We therefore had a pool of 113 presentation videos to use for Experiment 2: 41 from the Prezi condition (out of a possible 50), 40 from the PowerPoint condition (out of possible 49), and 32 from the oral presentation condition (out of a possible 47). The proportion of presentations that were video-recorded did not vary with their format, exact p = .61.

Some of the recorded presentations from Experiment 1 were unusable because of intractable quality issues (e.g., inaudible speech, incomplete video, partially occluded presenter), leaving a total of 89 usable videos (34 Prezi, 28 PowerPoint, 27 oral). The proportion of videos removed because of quality issues did not vary with presentation format, exact p = .57.

We randomly selected 25 videos in each format, resulting in a total pool of 75 videos. Because of a URL typo that was not detected until after testing, one PowerPoint video was not presented and participants assigned that video were not able to complete the experiment. Video length varied by format, F (2, 71) = 4.2, p = .02, with PowerPoint and Prezi presentations lasted longer than oral presentations ( M = 5.9, 6.0, and 4.6 minutes, respectively).

We were concerned that we could have, perhaps unconsciously, selected better stimuli in the Prezi condition, which would have biased the results. To ensure that our judgments of major audiovisual problems and subsequent exclusion of some videos were not biased, we recruited a separate group of participants to rate the audiovisual quality of the 113 presentation videos. Using the following language, we recruited 455 individuals from Amazon’s Mechanical Turk to serve as judges:

In this study you will judge the technical quality of three short videos. To participate you must have a high-speed Internet connection. We will compensate you $2 for 15–20 minutes of your time.

These participants were totally blind to the experimental hypotheses and manipulation. They completed the audiovisual rating task completely online via the Qualtrics survey platform, and were given the following instructions:

We need your help in determining the audiovisual quality of some Skype presentations we recorded. We want to know which presentations we can use for additional research, and which need to be eliminated due to major technical problems with the recordings. The sorts of technical problems that might exist in some of the videos are: incomplete recordings (the recording starts late or stops early), cropped recordings (the camera isn’t positioned properly), choppy or blurry video, and absent or inaudible audio.

You will watch a single presentation video. Please ignore any aspect of the recording other than its audiovisual quality. In particular, do not base your judgments on the presentation itself, including the presenter’s argument, appearance, or the nature of the accompanying slides. The only thing we care about is whether the audio and video were recorded properly.

Finally, please keep in mind that because these videos were recorded through Skype, even the best recordings are not very high quality.

These judge participants then watched a presentation video (selected at random), rated the quality of its audio and video (on a five-level scale from “very bad” to “very good”), and indicated whether or not there were “any major technical problems with the presentations audio or video”; those who reported major technical problems were asked to identify them.

To address any possibility of experimenter bias—which seemed unlikely, given that we designed the procedure from the outset to guard against such effects—we conducted a series of Presentation Format (Prezi, PowerPoint, oral) x Quality Judgment (inclusion, exclusion) ANOVAs to test 1) whether audiovisual quality was for any reason confounded with presentation format (i.e., the main effect of Presentation Format), 2) whether the excluded videos were indeed lower quality than the included videos (i.e., the main effect of Quality Judgment), and 3) whether our exclusion of videos was biased based on their format (i.e., the interaction between Presentation Format and Audiovisual Quality). We conducted the ANOVAs on the three measures of audiovisual quality collected from the independent judges: ratings of audio quality, ratings of video quality, and judgments of major audiovisual problems.

The results were straightforward: For all three dependent variables, there were no main effects of Presentation Format, p s > .13, but we did find a significant main effect of Quality Judgment (with included videos being judged better quality than excluded videos), all p s < .002, and did not find any interaction effects, all p s > .31. In other words, presentation format was not confounded with audiovisual quality, our judgments of quality corresponded to those of blind judges, and our exclusion of videos was unrelated to presentation format.

Participants completed the experiment entirely online through Qualtrics. After providing informed consent, and answering preliminary demographic and background questions (e.g., about their familiarity with business concepts and practices) they were told the following:

In this part of the study, you are going to play the role of a corporate executive for [Company X], an innovative clothing company. Another company, i-Mart, wants to sell [Company X’s] t-shirts in its many retail stores. You must decide whether or not to accept i-Mart's offer.

To help you make your decision, we will first provide you with some background on [Company X] and the i-Mart offer. You will see a series of short videos and text that describe relevant aspects of [Company X’s] origins, business model, practices, culture, and community. Please review this background material carefully.

Participants were then shown a series of brief video and textual descriptions of the fictionalized corporate scenario, including information on Company X’s business model, business processes, community, and culture. This material was an abridged version of what Experiment 1 presenter participants studied, but an expanded version of what Experiment 1 audience participants studied.

After viewing the multimedia case material, the participants were asked to identify what product Company X sells (a “trap” question to exclude non-serious participants) and to rate the background material on how engaging it was, how much they enjoyed it, how much they paid attention to it, and how difficult it was to understand.

Participants randomly assigned to the Prezi, PowerPoint, and Oral Presentation conditions were then told the following:

Now that you know a little bit about the company, you will watch a video presentation from another research participant. Just as you are playing the role of a [Company X] executive, the other participant is playing the role of i-Mart's Chief Marketing Office (CMO). In this presentation, he or she will try to convince you and your fellow [Company X] executives to accept i-Mart's offer.

Because this presentation is from another research participant playing the role of an i-Mart executive--and not an actual i-Mart executive--please disregard the presenter's appearance (clothing, age, etc). And because we did not professionally videorecord the presentation, please also try to disregard the relatively poor quality of the video compared to the videos you just viewed.

The purpose of this research is to understand what makes presentations effective. So please listen carefully and do your best to imagine that this is "real".

Identically to Experiment 1, participants rated the presentation on how organized, engaging, realistic, persuasive, and effective it was on a five-level scale from “not at all” to “extremely.” Using the same scale, these participants also rated the presenter on how organized, engaging, persuasive, effective, confident, enthusiastic, knowledgeable, professional, nervous, and boring he or she was.

Participants in the Prezi and PowerPoint groups were asked three additional questions. First, they were asked to rate the visual component of the presentation (i.e., the Prezi or the PowerPoint slides) on how organized, engaging, persuasive, effective, dynamic, visually compelling, distracting, informative, distinctive, and boring it was. Second, they were asked to rate whether the presentation had “not enough”, “too much” or an “about right” amount of text, graphs, images, and animations. And finally, there were asked to comment on the visual component of the presentations, including ways in which it could be improved.

All participants then summarized the presentation in their own words, with a minimum acceptable length of 50 characters. Participants were asked to rate how well they understood the “situation with [Company X] and I-Mart,” and to decide whether [Company X] should accept or reject i-Mart’s offer (on a 6-level scale, with the modifiers “definitely,” “probably,” and “possibly”).

In addition, we asked participants a series of recall and comprehension questions about the case. An example recall question is “According to the background materials and the presentation, approximately how many members does [Company X] have?”, with four possible answers ranging from 500,000 to 1.5 million. An example comprehension question is “According to the background materials, what is the biggest challenge [Company X] is facing?”, with possible answers ranging from “marketing” to “logistics.” These comprehension questions were based on the instructor’s guide to the business case material, and included open-ended questions (“Why do you think [Company X] should accept or reject i-Mart's offer?”). At this point we also asked another trap question (“What is 84 plus 27?”).

Finally, and after answering all questions about the business case and presentation, participants answered background questions about their experience with, knowledge of, and general preference for different presentation formats. They also rank-ordered the mini examples of Prezi, PowerPoint, and oral presentations in terms of their effectiveness. These background questions and tasks were the same as those used in Experiment 1.

Participants in the control condition completed the same protocol, with a few exceptions: First, instead of being shown presentations from Experiment 1, they viewed one of three instructional videos (matched for length with the Experiment 1 presentations). Before they viewed these videos they were told “Before you decide what to do about i-Mart's offer to [Company X], we would like you to watch an unrelated presentation and briefly answer some questions about it.” Second, they did not rate how realistic the presentation was, nor did they rate the visual component on how organized, engaging, persuasive, effective, dynamic, visually compelling, distracting, informative, distinctive, and boring it was. And finally, they did not complete the final set of background questions on the different presentation formats or rank-order the example presentations.

At the outset, participants rated oral and PowerPoint presentations as equally effective in general, and Prezi presentations as less effective than the other two formats. Just as we found in Experiment 1, participants rated themselves as more experienced and effective in making and oral and PowerPoint presentations compared to Prezi presentations. They also rated oral and PowerPoint presentations as more enjoyable and effective for them than viewing Prezi presentations. When asked how difficult it was to make the different types of presentations, they rated Prezi as more difficult than oral and PowerPoint presentations, and oral presentations as more difficult than PowerPoint ones. In terms of the number of presentations watched in the last year and in their lifetime—as well as the number of years of experience—they reported more experience watching oral compared to PowerPoint presentations, and more experience watching PowerPoint than watching Prezi presentations. The same pattern was true for their reported experience in making presentations, with one exception: They reported making more PowerPoint than oral presentations in their lifetime. Table 7 presents full descriptive and inference statistics for all self-reported measures of prior experience with and preexisting beliefs about Prezi, PowerPoint, and oral presentations. The experimental groups did not differ significantly on any of these variables.

https://doi.org/10.1371/journal.pone.0178774.t007

Most participants (78%) were either “not at all familiar” or “slightly familiar” with Company X, and the modal participant reported being “somewhat experienced” with “concepts and practices from the business world, such as strategy, innovation, product development, sales, and marketing.” The groups did not differ significantly on these variables, nor did they differ on demographic variables such as age, gender, or education.

For overall judgments of the presentations, participants rated Prezi as more organized, effective, engaging, and persuasive than PowerPoint and oral presentations, and rated PowerPoint no differently than oral presentations. They also rated Prezi presenters as more organized, knowledgeable, effective, and professional than PowerPoint presenters and oral presenters; Prezi presenters were not rated differently from other presentations on how nervous, boring, enthusiastic, confident, persuasive, or engaging they were, and PowerPoint presenters were rated no differently than oral presenters on all dimensions. In judging the visual components of the Prezi and PowerPoint presentations, the audience rated Prezi presentations as more dynamic, visually compelling, and distinctive than PowerPoint slides, and marginally more effective and persuasive.

Examining the magnitude of mean differences, some effects are clearly larger than others. Most notably, Prezi presentations are rated as most organized and visually dynamic, and Prezi presenters are rated as most organized. Fig 4 and Table 8 present the descriptive and inferential statistics, respectively, for these audience ratings.

https://doi.org/10.1371/journal.pone.0178774.t008

Note: rating dimensions are ordered by the magnitude of the difference between Prezi and the other presentation formats; for dimensions with no significant differences between presentation formats, only the overall mean is displayed.

https://doi.org/10.1371/journal.pone.0178774.g004

The modal participant rated the background case material on Company X as “very engaging” and “completely enjoyable,” reported “mostly” understanding the situation with i-Mart and Company X, and rated the presentations as “very realistic.” Seventy percent of participants expected to do “somewhat well” or “very well” when quizzed about the case. There were no significant group differences on any of these variables.

Audience decision-making.

Did the presentations actually influence participants’ core judgment of the business scenario and, if so, was one presentation format more effective than others?

Participants who received a Prezi presentation accepted i-Mart’s offer 53.7% of the time, participants who received a PowerPoint presentation accepted the offer 49.8% of the time, participants exposed to an oral presentation accepted it 45.5% of the time, and participants exposed to the control presentation accepted it 37.5% of the time (see Fig 5 ). In an omnibus test, these differences were significant, exact p = .002. Specific comparisons revealed that Prezi presentations were significantly more influential than control presentations, exact p = 0003, marginally more influential than oral presentations, exact p = .06, and no more influential than PowerPoint presentations, exact p = .39; PowerPoint presentations were significantly more influential than control presentations, exact p = .006, but not oral presentations, exact p = .34; oral presentations were marginally more influential than control presentations, exact p = .07. In order to investigate the impact of presentation software on decision-making, we contrasted the Prezi and PowerPoint groups with the oral presentation groups. We found a marginally significant effect, exact p = .06.

https://doi.org/10.1371/journal.pone.0178774.g005

On the whole, therefore, the participants’ decision-making results were concordant descriptively (if not always inferentially) with the rating results.

If participants’ perceptions of the presentations and decisions about the case were both influenced by presentation format, then we would expect them to be associated with each other. And this is indeed what we found. Excluding participants in the control group (who did not make judgments about comparable presentations), those who rejected the i-Mart offer rated presentations as worse than those who accepted the i-Mart offer. This was true for 23 of the 24 rating dimensions (“visually boring” was the exception), with the largest effects for ratings of effectiveness and persuasiveness. Those who rejected the offer rated the overall presentation, visual aids, and presenter as less effective than those who accepted the offer, with effect sizes (Cohen’s d ) of .93, .83, and .78, respectively. These effects were consistent across formats, all interaction p s > .05.

We conducted an analogous set of analyses that preserved the original 6-level scale of the decision variable (“possibly accept,” “probably accept,” “definitely accept,” “possibly reject,” “probably reject,” “definitely reject”). These analyses produced qualitatively identical results, both in terms of decision-making as a function of group assignment and the correlation between decision-making and presentation ratings.

Memory and comprehension.

Participants’ performance on the four rote memory questions did not vary across conditions, nor did their correct identification (according to the case designers) of reasons to accept or reject the offer, with one exception: Compared to those in the treatment groups, control participants were more likely to identify Company X’s ability to meet production demand as a reason to reject the i-Mart, omnibus exact p = .00004.

Correlates of presentation outcomes.

There were no notable correlations between demographic variables and participants’ ratings or decisions. In particular, participants’ experience with or preexisting beliefs about each presentation format did not correlate with their ratings of the experimental presentations, mirroring the results from Experiment 1 (but with much greater statistical power). Presentation length or recording quality (as assessed by the independent judges) did not correlate with presentation outcomes.

Participants’ success in distinguishing better from worse presentations of each format—that is, their rank-ordering of short expert-created examples—correlated slightly with their evaluations of the presentations. Most notably, the better participants did on the rank-ordering PowerPoint task, the worse they rated PowerPoint (but not Prezi) presentations on visual dimensions; the same was true for the Prezi task and presentations. For example, participants’ performance in the PowerPoint task correlated negatively with their judgments of how “visually dynamic” PowerPoint presentations were, r = -.22, p = .0005, and participants’ performance on the Prezi task correlated negatively with their judgments of how “visually dynamic” Prezi presentations were, r = -.16, p = .009. Thus, individuals with more expertise in PowerPoint and Prezi were more critical of PowerPoint and Prezi presentations, respectively.

Audiovisual attributes of Prezi and PowerPoint presentations.

To understand the media attributes and psychological mechanisms that underlie the observed effects of format, we examined how participants’ judgments about amount of text, graphs, animations, and images in the presentations correlated with their judgments of the presentations, the visual component of the presentations, and the presenters themselves. To examine these relationships, we conducted one-way ANOVAs with the various ratings as the dependent variables, and participants’ judgments (“not enough,” “about right,” “too much”) about the amount of text, graphs, animations, and images in the PowerPoint and Prezi presentations as the independent variable. For nearly all (80 of 96) of these ANOVAs, the results were highly significant, p s < .001. In judging the amount of text, participants typically rated “too much” or “not enough” text as worse than an “about right” amount; in judging graphs, images, and animations, participants typically rated “too much” and “just right” both as equally better than “not enough.” Averaging across all rating dimensions, the text and graph effects were over twice as large as the animation and image effects; averaging across all attributes, the effects for visual ratings was over twice as large as the effects for presenter and overall ratings. Participants’ judgments about the media attributes of presentations did, therefore, relate to their overall assessments of the presenters and presentations.

Summing across PowerPoint and Prezi presentations, the modal participant indicated that there was the “about right” amount of text, graphs, animations, and images. Only 21% of participants thought there was not enough or too much text; for the other dimensions, this percentage ranged from 42–51%. More participants indicated that there was not enough text, graphs, and animations in PowerPoint presentations than Prezi presentations, with animation as the most distinguishing attribute. Table 9 presents the descriptive and inferential statistics for these variables.

https://doi.org/10.1371/journal.pone.0178774.t009

As shown in Table 10 , participants’ judgments about the audiovisual attributes of the Prezi and PowerPoint presentations were associated with the decision about the business scenario. Individuals who reported that there was not enough text, graph, animation, or images tended to reject the offer for i-Mart, whereas those who reported that there was the “about right” amount of those attributes tended to accept the offer. This effect was particularly pronounced for judgments of graphs and text. Participants who reported too much text also tended to reject the offer.

https://doi.org/10.1371/journal.pone.0178774.t010

In sum, participants’ perceptions of presenters and the presentations correlated with their evaluations of the amount of text, graphs, images, and animations that were included in the presentations. Presenters and presentations were rated worse if they had too much or not enough text, and not enough graphs, images, and animations; in terms of audience decision-making, presentations were less effective if they contained too much or not enough text, or not enough graphs, animations, and images. PowerPoint presentations were judged to have too little of all attributes, particularly animation.

Replicating results from Experiment 1, participants rated presentations made with Prezi as more organized, engaging, persuasive, and effective than both PowerPoint and oral presentations. This remained true despite participants’ preexisting bias against Prezi and the different context of Experiment 2: the audience did not view multiple presentations of different formats and presentations were prerecorded instead of live. Extending the Experiment 1 results, participants also judged Prezi presentations as better in various ways (e.g., more visually compelling, more dynamic) than PowerPoint presentations; participants even rated Prezi presenters more highly (e.g., more knowledgeable, more professional) than PowerPoint presenters.

In making decisions as corporate executives, participants were persuaded by the presentations. Compared to the baseline decisions of the control group, those in the treatment group shifted their decisions by 16.2%, 12.3%, and 8.0% depending on whether they viewed Prezi, PowerPoint, or oral presentations, respectively. The non- or marginal significance of some between-format comparisons (e.g., PowerPoint versus Prezi) is difficult to interpret. We hesitate to dismiss these differences as statistical noise given their general alignment with rating results, as well as the correlation between business decisions and presentation ratings (which do vary significantly with format). For the more objective outcome of decision-making, we can, at the very least, provisionally conclude that Prezi presentations are more effective than oral presentations, and that software-aided presentations are more effective than oral presentations.

We did not find any evidence that the presentations affected participants’ memory or understanding of the case, nor did we find evidence that certain presentation formats impacted learning more than others. Given the goals of the presentations and design of the experiment, however, we hesitate to draw any conclusions from these null results.

General discussion

The most important finding across the two experiments is easy to summarize: Participants evaluated Prezi presentations as more organized, engaging, persuasive, and effective than both PowerPoint and oral presentations. This finding was true for both live and prerecorded presentations, when participants rated or ranked presentations, and when participants judged multiple presentations of different formats or only one presentation in isolation. Results from Experiment 2 demonstrate that these presentations influenced participants’ core judgments about a business decision, and suggest that Prezi may benefit both behavioral and experiential outcomes. We have no evidence, however, that Prezi (or PowerPoint or oral presentations) facilitate learning in either presenters or their audience.

Several uninteresting explanations exist for the observed Prezi effects, none of which posit any specific efficacy of Prezi or ZUIs in general: namely, novelty, bias, and experimenter effects. We consider each in turn.

Novelty heavily influences both attention and memory [ 87 , 88 ], and the benefits of new media have sometimes dissipated over time—just as one would expect with novelty effects [ 3 ]. However, we found no evidence that novelty explains the observed benefits of Prezi: Participants who were less familiar with Prezi did not evaluate Prezi presentations more favorably, and only a small fraction of participants who favored Prezi explained their preference in terms of novelty. We therefore are skeptical that mere novelty can explain the observed effects.

We also considered the possibility that participants had a pre-existing bias for Prezi. This seems unlikely because presenter participants were selected based only on minimal experience with both PowerPoint and Prezi and were assigned randomly to the experimental groups; audience participants from both experiments were selected based merely on high-speed internet access, and the words “Prezi” and “PowerPoint” were not used in any audience recruitment material. In fact, both sets of participants entered the research with biases against Prezi, not for Prezi: They reported more experience with PowerPoint and oral presentations than Prezi, and perceived PowerPoint and oral presentations as more (not less) efficacious than Prezi. Thus, we reject the idea that the results simply reflect pre-existing media biases.

For many reasons, we also find it unlikely that experimenter effects—including demand characteristics (i.e., when participants conform to the experimenters’ expectations)—can explain the observed effects. First, at the outset we did not have strong hypotheses about the benefits of one format over the others. Second, the results are subtle in ways that neither we nor a demand characteristics hypothesis would predict: the effects on subjective experience diverged somewhat from the effects on decision-making, and there were no memory or comprehension effects. Third, the between-participants design of Experiment 2 (and between-participants analysis of Experiment 1 ) limited participants’ exposure to a single presentation format, thereby minimizing their ability to discern the experimental manipulation or research hypotheses. Fourth, we ensured that the presentations were equally high-quality; we did not unconsciously select Prezi presentations that happened to be higher quality than presentations in the other formats. Fifth, the random assignment of presenters to format limits the possible confounding of presenter variables with presentation formats or qualities; and no confounding with format was observed in presenters’ preexisting beliefs, prior experience, or demographics. And finally, in Experiment 2 we only explicitly mentioned or asked participants questions about Prezi, PowerPoint, and oral presentations at the conclusion of the experiment, after collecting all key outcome data.

We therefore conclude that the observed effects are not confounds or biases, but instead reflect a true and specific benefit of Prezi over PowerPoint or, more generally, ZUIs over slideware. If, however, these experimental effects merely reveal that Prezi is more user-friendly than PowerPoint—or that PowerPoint’s default templates encourage shallow processing by “[fetishizing] the outline at the expense of the content” [ 89 ] (pB26)—then we have learned little about the practice or psychology of communication. But if these effects instead reflect intrinsic properties of ZUIs or slideware, then they reveal more interesting and general insights about effective communication.

It is difficult to understand Prezi’s benefits in terms of user-friendliness because the odds were so clearly stacked in PowerPoint’s favor. Presenters were much more experienced in using PowerPoint than Prezi and rated PowerPoint as easier to use than Prezi. Especially given the task constraints—participants only had 45 minutes to prepare for a 5-minute presentation on a relatively new, unfamiliar topic—Prezi’s user interface would have to be improbably superior to PowerPoint’s interface to overcome these handicaps. Moreover, participants’ prior experience with PowerPoint or Prezi did not correlate with their success as presenters, as one would expect under an ease-of-use explanation. Finally, audience participants did not simply favor the Prezi presentations in an even, omnibus sense—they evaluated Prezi as better in particular ways that align with the purported advantages of ZUIs over slideware. This pattern of finding makes most sense if the mechanism were at the level of media, not software.

Participants’ evaluations of Prezi were particularly telling in three ways. First, in participants’ own words (from Experiment 1 ), they frequently described Prezi as engaging , interactive , visually compelling , visually pleasing , or vivid , and PowerPoint as concise , clear , easy to follow , familiar , professional , or organized . Second, in participants’ ratings (from Experiment 2 ), the visuals from Prezi presentations were evaluated as significantly more dynamic, visually compelling, and distinctive than those from PowerPoint presentations. And third, in judging the audiovisual attributes of presentations, participants’ identified animations as both the attribute most lacking in presentations and the attribute that most distinguished Prezi from PowerPoint; furthermore, the more a presentation was judged as lacking animation, the worse it was rated. Taken together, this evidence suggests that Prezi presentations were not just better overall, but were better at engaging visually with their audience through the use of animation. Because ZUIs are defined by their panning and zooming animations—and animation is an ancillary (and frequently misused) feature of slideware—the most parsimonious explanation for the present results is in terms of ZUIs and slideware in general, not Prezi and PowerPoint in particular. The medium is not the message, but it may be the mechanism.

The animated nature of ZUIs makes more sense as possible mechanism for the observed effects when one considers relevant literature on animation. Past research has shown that animation can induce physiological and subjective arousal (e.g., [ 90 , 91 ]) and facilitate attention, learning, and task performance (e.g., [ 92 – 94 ]; but see also [ 95 , 96 ]). Most pertinently, people appear to prefer animated media over static media. Participants rate animated online advertisements as more enjoyable, persuasive, effective, and exciting than static online advertisements [ 97 , 98 ], animated websites as more likeable, engaging, and favorable than static websites [ 99 ], and animated architectural displays as clearer than static displays [ 100 ]. In an experiment of online academic lectures, participants preferred whiteboard-style animations over a slideware-style version matched for both visual and audio content [ 101 ]. Moreover, ZUI’s use of animation aligns with recommended principles for using animation effectively in presentations, which include the creation of a large virtual canvas and the use of zooming to view detail [ 102 ]. Slideware, on the other hand, encourages the use of superfluous animation in slide transitions and object entrances/exits, despite evidence that adding such “seductive details” to multimedia presentations can be counterproductive [ 72 ].

Therefore, we not only conclude that audiences prefer Prezi over PowerPoint presentations, but also conclude that their preference is rooted in an intrinsic attribute of ZUIs: panning and zooming animations. Compared to slideware’s sequential, linear transitions (and oral presentations’ total lack of visual aids), zooming and panning over a virtual canvas is a more engaging and enjoyable experience for an audience.

From this perspective, the reason that participants rated Prezi presentations as more persuasive, effective, and organized than other presentations—and Prezi presenters as more knowledgeable, professional, effective, and organized than other presenters—was because they confuse media with messages and messengers. Dual-process models of persuasion contend that opinion change occurs through not just slow deliberations grounded in logic and reason but also through fast shortcuts rooted in associations and cues [ 103 – 106 ]. If better presenters with better arguments tend to give better presentations, then an audience’s experience while viewing a presentation may shade their judgments about its presenter or argument. This is the same basic logic of research that demonstrates PowerPoint’s persuasion advantage over oral presentations [ 53 , 54 ]. Just as audiences appear more persuaded by slideware than by oral presentations, they also appear more persuaded by ZUI than by slideware presentations. But unlike past research, we do not argue that audience members use technological sophistication as a cue for argument quality [ 53 ] or presenter preparedness [ 54 ]; instead, we suggest that they use their subjective viewing experience as a heuristic for judging both presentations and presenters. Because ZUI presentations are more engaging than slideshows, ZUI presentations and presenters are judged more positively than slideshows.

Concluding remarks

Media research, including research into presentation software, is plagued methodologically by a lack of experimental control, the unjustifiable assumption that media effects are constant across individuals and content, and a failure to account for the biases of all involved: the presenters, the audiences, and the researchers. In the research reported here we strived to overcome these challenges by randomly assigning presenters and audience members to competing presentation formats, blinding them to the experimental manipulations, and sampling a sufficient array of presentations within each format.

Our conclusions about the advantages of ZUIs (such as Prezi) over slideware (such as PowerPoint) and oral presentations are, of course, tentative. Further research will need to replicate the findings across different presentation contexts, clarify whether the subjective benefits of ZUIs over slideware result in decision-making or behavioral advantages, and better investigate the precise media attributes responsible for these advantages. Like others [ 107 ], we caution against technological determinism: Presentation medium is but one of many factors that determine presentation success, and presentations that rely on any given medium can succeed or fail. Because slideware can be used to zoom and pan over a virtual canvas just as ZUIs can be used to create slideshows, the benefits of ZUIs over slideware are ultimately based on affordances: How much do certain formats encourage or enable psychologically advantageous media attributes, such as zooming and panning animations?

In many ways, it is surprising that we found any effects of presentation medium. The presentations differed in many ways aside from their format, ways that surely influenced their effectiveness: Each presentation was made by a different person (sampled from a diverse pool of participants), presenters chose what content to include in their presentation, and presenters decided how to convey that content within their assigned format. Under real-world circumstances in which presentations of different formats are actually contrasted with each other, we expect this background “noise” to be greatly reduced and impact of format correspondingly greater.

• The Advantages of Using Multimedia in Web Design

Visual communication involves the use of visual elements, such as drawings, illustrations and electronic images, to convey ideas and information to an audience. During presentations, business managers that properly use visual aids to communicate information will have greater success in maintaining the attention of their staff, and staff is more likely to remember the information. A potential downside of visual communication involves the use of poorly designed visual aids that are difficult to understand or see. If irrelevant information is presented, images can also be distracting and impede the understanding of concepts they should be trying to clarify.

Advantage: Aids Understanding

Technology has led to explosive growth in the use of images to communicate and understand the world around us. The use of internet technology has turned business users into active participants that can use words and images to communicate with customers and make their brands more visible to the world. Technology that provides images, video and apps gives business owners a variety of tools to use to attract customers and expand their markets. The combination of words and images has a powerful effect on the communication of ideas.

Advantage: Supports Oral Communication

Oral communication is enhanced when visual aids are used. It’s important to pair the correct visual aid with the type of oral information presented. For example, a manager discussing a data-intensive topic, such as a company’s fourth-quarter financial results, should consider passing out a handout that details the financial information. Presenting the information in a table format, or using a chart or graph to highlight key financial results, increases the audience's understanding and encourages participants to ask questions.

Disadvantage: Design Issues

If a visual aid is not properly designed for its intended use and audience, it can lead to a breakdown in communication. For example, a business person presenting a new product launch must consider the size and color of the product images he wants to show to the audience. The size of his audience determines the size of the pictures he will present. A large audience requires large images that might be shown on a screen so they are visible by everyone. A small audience, such as one that can be seated around a conference room table, can be shown images from a brochure.

Disadvantage: Distracts From the Message

A visual aid with the wrong information can cause a distraction and detract from the message the image is supposed to convey. For example, a discussion of a company's U.S. manufacturing plants might be accompanied by a map showing the location of these plants within their respective states. But if you include irrelevant information, such as tourist sites, it can distract the audience from the purpose of the map – to show the location of manufacturing plants. If you are making a presentation using slides, always try to be in charge of the remote or computer used to click to the next slide to ensure your words coincide with the graphics presented.

Oral presentations

Using oral presentations to assess learning

Introduction.

Oral presentations are a form of assessment that calls on students to use the spoken word to express their knowledge and understanding of a topic. It allows capture of not only the research that the students have done but also a range of cognitive and transferable skills.

Different types of oral presentations

A common format is in-class presentations on a prepared topic, often supported by visual aids in the form of PowerPoint slides or a Prezi, with a standard length that varies between 10 and 20 minutes. In-class presentations can be performed individually or in a small group and are generally followed by a brief question and answer session.

Oral presentations are often combined with other modes of assessment; for example oral presentation of a project report, oral presentation of a poster, commentary on a practical exercise, etc.

Also common is the use of PechaKucha, a fast-paced presentation format consisting of a fixed number of slides that are set to move on every twenty seconds (Hirst, 2016). The original version was of 20 slides resulting in a 6 minute and 40 second presentation, however, you can reduce this to 10 or 15 to suit group size or topic complexity and coverage. One of the advantages of this format is that you can fit a large number of presentations in a short period of time and everyone has the same rules. It is also a format that enables students to express their creativity through the appropriate use of images on their slides to support their narrative.

When deciding which format of oral presentation best allows your students to demonstrate the learning outcomes, it is also useful to consider which format closely relates to real world practice in your subject area.

What can oral presentations assess?

The key questions to consider include:

• what will be assessed?
• who will be assessing?

This form of assessment places the emphasis on students’ capacity to arrange and present information in a clear, coherent and effective way’ rather than on their capacity to find relevant information and sources. However, as noted above, it could be used to assess both.

Oral presentations, depending on the task set, can be particularly useful in assessing:

• knowledge skills and critical analysis
• applied problem-solving abilities
• ability to research and prepare persuasive arguments
• ability to generate and synthesise ideas
• ability to communicate effectively
• ability to present information clearly and concisely
• ability to present information to an audience with appropriate use of visual and technical aids
• time management
• interpersonal and group skills.

When using this method you are likely to aim to assess a combination of the above to the extent specified by the learning outcomes. It is also important that all aspects being assessed are reflected in the marking criteria.

In the case of group presentation you might also assess:

• level of contribution to the group
• ability to contribute without dominating
• ability to maintain a clear role within the group.

See also the ‘ Assessing group work Link opens in a new window ’ section for further guidance.

As with all of the methods described in this resource it is important to ensure that the students are clear about what they expected to do and understand the criteria that will be used to asses them. (See Ginkel et al, 2017 for a useful case study.)

Although the use of oral presentations is increasingly common in higher education some students might not be familiar with this form of assessment. It is important therefore to provide opportunities to discuss expectations and practice in a safe environment, for example by building short presentation activities with discussion and feedback into class time.

Individual or group

It is not uncommon to assess group presentations. If you are opting for this format:

• will you assess outcome or process, or both?
• how will you distribute tasks and allocate marks?
• will group members contribute to the assessment by reporting group process?

Assessed oral presentations are often performed before a peer audience - either in-person or online. It is important to consider what role the peers will play and to ensure they are fully aware of expectations, ground rules and etiquette whether presentations take place online or on campus:

• will the presentation be peer assessed? If so how will you ensure everyone has a deep understanding of the criteria?
• will peers be required to interact during the presentation?
• will peers be required to ask questions after the presentation?
• what preparation will peers need to be able to perform their role?
• how will the presence and behaviour of peers impact on the assessment?
• how will you ensure equality of opportunities for students who are asked fewer/more/easier/harder questions by peers?

Hounsell and McCune (2001) note the importance of the physical setting and layout as one of the conditions which can impact on students’ performance; it is therefore advisable to offer students the opportunity to familiarise themselves with the space in which the presentations will take place and to agree layout of the space in advance.

Good practice

As a summary to the ideas above, Pickford and Brown (2006, p.65) list good practice, based on a number of case studies integrated in their text, which includes:

• make explicit the purpose and assessment criteria
• use the audience to contribute to the assessment process
• record [audio / video] presentations for self-assessment and reflection (you may have to do this for QA purposes anyway)
• keep presentations short
• consider bringing in externals from commerce / industry (to add authenticity)
• consider banning notes / audio visual aids (this may help if AI-generated/enhanced scripts run counter to intended learning outcomes)
• encourage students to engage in formative practice with peers (including formative practice of giving feedback)
• use a single presentation to assess synoptically; linking several parts / modules of the course
• give immediate oral feedback
• link back to the learning outcomes that the presentation is assessing; process or product.

Neumann in Havemann and Sherman (eds., 2017) provides a useful case study in chapter 19: Student Presentations at a Distance, and Grange & Enriquez in chapter 22: Moving from an Assessed Presentation during Class Time to a Video-based Assessment in a Spanish Culture Module.

Diversity & inclusion

Some students might feel more comfortable or be better able to express themselves orally than in writing, and vice versa . Others might have particular difficulties expressing themselves verbally, due for example to hearing or speech impediments, anxiety, personality, or language abilities. As with any other form of assessment it is important to be aware of elements that potentially put some students at a disadvantage and consider solutions that benefit all students.

Academic integrity

Oral presentations present relative low risk of academic misconduct if they are presented synchronously and in-class. Avoiding the use of a script can ensure that students are not simply reading out someone else’s text or an AI generated script, whilst the questions posed at the end can allow assessors to gauge the depth of understanding of the topic and structure presented. (Click here for further guidance on academic integrity .)

Recorded presentations (asynchronous) may be produced with help, and additional mechanisms to ensure that the work presented is their own work may be beneficial - such as a reflective account, or a live Q&A session. AI can create scripts, slides and presentations, copy real voices relatively convincingly, and create video avatars, these tools can enable students to create professional video content, and may make this sort of assessment more accessible. The desirability of such tools will depend upon what you are aiming to assess and how you will evaluate student performance.

Student and staff experience

Oral presentations provide a useful opportunity for students to practice skills which are required in the world of work. Through the process of preparing for an oral presentation, students can develop their ability to synthesise information and present to an audience. To improve authenticity the assessment might involve the use of an actual audience, realistic timeframes for preparation, collaboration between students and be situated in realistic contexts, which might include the use of AI tools.

As mentioned above it is important to remember that the stress of presenting information to a public audience might put some students at a disadvantage. Similarly non-native speakers might perceive language as an additional barrier. AI may reduce some of these challenges, but it will be important to ensure equal access to these tools to avoid disadvantaging students. Discussing criteria and expectations with your students, providing a clear structure, ensuring opportunities to practice and receive feedback will benefit all students.

Some disadvantages of oral presentations include:

• anxiety - students might feel anxious about this type of assessment and this might impact on their performance
• time - oral assessment can be time consuming both in terms of student preparation and performance
• time - to develop skill in designing slides if they are required; we cannot assume knowledge of PowerPoint etc.
• lack of anonymity and potential bias on the part of markers.

From a student perspective preparing for an oral presentation can be time consuming, especially if the presentation is supported by slides or a poster which also require careful design.

From a teacher’s point of view, presentations are generally assessed on the spot and feedback is immediate, which reduces marking time. It is therefore essential to have clearly defined marking criteria which help assessors to focus on the intended learning outcomes rather than simply on presentation style.

Online presentations may be audio-only or a combination of video plus audio (i.e. videoconferencing). Audio-only teleconferencing is efficient and inexpensive if there is a need to supply a select group of people with the same information at the same time. However, if the audience becomes too large or the audio quality is not high, this method becomes an ineffective way of communicating. Normally, people rely on visual clues to decide when to speak and when to listen, as well as to understand what is being said. As with any meeting, a virtual meeting is undertaken to achieve some objective, but expands the possibilities by reducing the usual barriers to meeting for individuals in different locations, namely the physical separation and the time and cost of travelling to a common venue. An online meeting can be conducted at any time and location. For this reason, online meetings have enjoyed considerable attention in the commercial, academic and other fields. Face-to-face meetings offer networking opportunities and the chance for personal engagement. Coffee break discussions, socialising events and conference meals help teams to establish themselves. When attendees are at a face-to-face event, they tend to be less easily distracted from the business of the meeting than may occur with an online event. Both the presenters and the audience members can read many body language clues which reveal how engaged they are with the topic and what their feeling may be. These clues can be lost with videoconferencing. Teams tend to trust each other more when they have actually met in person.

The 8 Types of Presentation Styles: Which Category Do You Fall Into?

Updated: December 16, 2020

Published: September 24, 2018

Types of Presentations

• Visual Style
• Freeform Style
• Instructor Style
• Coach Style
• Storytelling Style
• Connector Style
• Lessig Style
• Takahashi Style

Everyone on the internet has an opinion on how to give the “perfect” presentation.

One group champions visual aids, another thinks visual aids are a threat to society as we know it. One expert preaches the benefits of speaking loudly, while another believes the softer you speak the more your audience pays attention. And don’t even try to find coordinating opinions on whether you should start your presentation with a story, quote, statistic, or question.

But what if there wasn’t just one “right” way to give a presentation? What if there were several? Below, I’ve outlined eight types of presentation styles. They’re used by famous speakers like Steve Jobs and Al Gore -- and none of them are wrong.

Check out each one and decide which will be most effective for you.

Types of Presentation Styles

1. visual style.

What it is: If you’re a firm believer slides simply exist to complement your talking points, this style is for you. With this speaking style, you might need to work a little harder to get your audience engaged, but the dividends can be huge for strong public speakers, visionaries, and storytellers.

When to use it: This style is helpful when speaking to a large audience with broad interests. It’s also great for when you need to throw together slides quickly.

Visual style presenter: Steve Jobs

2. Freeform Style

What it is: This impromptu style of presenting doesn’t require slides. Instead, the speaker relies on strong stories to illustrate each point. This style works best for those who have a short presentation time and are extremely familiar with their talking points.

When to use it: Elevator pitches, networking events, and impromptu meetings are all scenarios in which to use a freeform style of speaking. You’ll appear less rehearsed and more conversational than if you were to pause in the middle of a happy hour to pull up your presentation on a tablet.

Freeform style presenter: Sir Ken Robinson

3. Instructor Style

What it is: This presentation style allows you to deliver complex messages using figures of speech, metaphors, and lots of content -- just like your teachers and professors of old. Your decks should be built in logical order to aid your presentation, and you should use high-impact visuals to support your ideas and keep the audience engaged.

When to use it: If you’re not a comfortable presenter or are unfamiliar with your subject matter (i.e., your product was recently updated and you’re not familiar with the finer points), try instructor-style presenting.

Instructor style presenter: Al Gore

4. Coach Style

What it is: Energetic and charismatic speakers gravitate towards this style of presenting. It allows them to connect and engage with their audience using role play and listener interaction.

When to use it: Use this presentation style when you’re speaking at a conference or presenting to an audience who needs to be put at ease. For example, this style would work well if you were speaking to a group of executives who need to be sold on the idea of what your company does rather than the details of how you do it.

Coach style presenter: Linda Edgecombe

5. Storytelling Style

What it is: In this style, the speaker relies on anecdotes and examples to connect with their audience. Stories bring your learning points to life, and the TED’s Commandments never let you down: Let your emotions out and tell your story in an honest way.

When to use it: Avoid this style if you’re in the discovery phase of the sales process. You want to keep the conversation about your prospect instead of circling every point or question back to you or a similar client. This style is great for conference speaking, networking events, and sales presentations where you have adequate time to tell your stories without taking minutes away from questions.

Storytelling style presenter: Jill Bolte Taylor

6. Connector Style

What it is: In this style, presenters connect with their audience by showing how they’re similar to their listeners. Connectors usually enjoy freeform Q&A and use gestures when they speak. They also highly encourage audience reaction and feedback to what they’re saying.

When to use it: Use this style of presenting early in the sales process as you’re learning about your prospect’s pain points, challenges, and goals. This type of speaking sets your listener at ease, elicits feedback on how you’re doing in real time, and is more of a dialogue than a one-sided presentation

Connector style presenter: Connie Dieken

7. Lessig Style

What it is: The Lessig Style was created by Lawrence Lessig , a professor of law and leadership at Harvard Law School. This presentation style requires the presenter to pass through each slide within 15 seconds. When text is used in a slide, it’s typically synchronized with the presenter’s spoken words.

When to use it: This method of presentation is great for large crowds -- and it allows the speaker to use a balance of text and image to convey their message. The rapid pace and rhythm of the slide progression keeps audiences focused, engaged, and less likely to snooze.

Lessig style presenter: Lawrence Lessig

8. Takahashi Style

What it is: This method features large, bold text on minimal slides. It was devised by Masayoshi Takahashi , who found himself creating slides without access to a presentation design tool or PowerPoint. The main word is the focal point of the slide, and phrases, used sparingly, are short and concise.

When to use it: If you find yourself in Takahashi’s shoes -- without presentation design software -- this method is for you. This style works well for short presentations that pack a memorable punch.

Takahashi style presenter: Masayoshi Takahashi

Slides from one of Takahashi’s presentations:

Whether you’re speaking on a conference stage or giving a sales presentation , you can find a method that works best for you and your audience. With the right style, you’ll capture attention, engage listeners, and effectively share your message. You can even ask an  AI presentation maker  tool to create presentations for you in your preferred style

3 Group Presentation Pitfalls — and How to Avoid Them

• Allison Shapira

Strategies for a polished, unified final product.

Putting together an effective group presentation takes teamwork and coordination so it doesn’t look like a patchwork quilt. And yet, many of us never budget the time to fully prepare. The author outlines some of the common mistakes people make in group presentations and offers best practices to keep you on track. 

Many of us have experienced poor group presentations. If you’re giving one, it’s the last-minute scramble the night before to decide who is presenting which part of the presentation. If you’re observing one, it’s the chaos of hearing multiple people talking over one another or, even worse, simply reading their slides word-for-word and ignoring their audience.

Advantages and Disadvantages of Oral Communication

Looking for advantages and disadvantages of Oral Communication?

We have collected some solid points that will help you understand the pros and cons of Oral Communication in detail.

But first, let’s understand the topic:

What is Oral Communication?

Oral communication refers to the exchange of information and ideas through spoken words, often used in meetings, presentations, and interpersonal communication.

What are the advantages and disadvantages of Oral Communication

The following are the advantages and disadvantages of Oral Communication:

Advantages of Oral Communication

• Clear Communication – Oral communication enables us to communicate effectively and clearly. We can express our thoughts, ideas, and feelings in a way that is easily understood by the listener. Oral communication helps us to avoid misunderstandings and ensures that our message is conveyed accurately.
• Immediate Feedback – With oral communication, we get immediate feedback from the listener. We can gauge the listener’s understanding and adjust our message accordingly. Immediate feedback helps us to clarify our message and ensures that the listener understands our message correctly.
• Non-Verbal Cues – Oral communication involves the use of non-verbal cues such as facial expressions, gestures, and tone of voice, which help to convey the message effectively. These non-verbal cues add meaning and emphasis to our message, making it more impactful and memorable.
• Builds Relationships – Oral communication helps in building relationships with others. When we communicate orally, we establish a personal connection with the listener, which is not possible with written communication. Oral communication helps in creating trust, understanding, and empathy between individuals.
• Improves Public Speaking Skills – Oral communication helps in improving public speaking skills, which is a valuable skill in various fields. Public speaking involves delivering a speech or presentation to a large audience, and oral communication is essential in delivering an effective speech or presentation.

Disadvantages of Oral Communication

• Misunderstandings – With oral communication, there is always a risk of misinterpreting or misunderstanding what someone else is saying. This can happen due to language barriers, unclear pronunciation, or miscommunication of ideas.
• Forgetfulness – Another disadvantage of oral communication is that it’s easy to forget what was said. Unlike written communication, which can be revisited at any time, oral communication is ephemeral and can be easily forgotten.
• Distractions – During an oral communication, it’s easy to get distracted by external factors such as background noise, other people’s conversations, or one’s own thoughts. This can lead to a loss of focus and missed information.
• Lack of record-keeping – Oral communication leaves no tangible record of what was said. This can be a problem if there is a need to reference the conversation at a later time or if there is a dispute over what was discussed.
• Time constraints – Oral communication can also be limited by time constraints. Conversations may need to be cut short due to scheduling conflicts or other priorities, which can make it difficult to fully explore all ideas or concerns.

Chapter 6: Developing Presentations

39 Methods of Presentation Delivery

The importance of delivery.

Delivery is what you are probably most concerned about when it comes to giving presentations. This chapter is designed to help you give the best delivery possible and eliminate some of the nervousness you might be feeling. To do that, you should first dismiss the myth that public speaking is just reading and talking at the same time. Speaking in public has more formality than talking. During a speech, you should present yourself professionally. This doesn’t necessarily mean you must wear a suit or “dress up”, but it does mean making yourself presentable by being well groomed and wearing clean, appropriate clothes. It also means being prepared to use language correctly and appropriately for the audience and the topic, to make eye contact with your audience, and to look like you know your topic very well.

While speaking has more formality than talking, it has less formality than reading. Speaking allows for flexibility, meaningful pauses, eye contact, small changes in word order, and vocal emphasis. Reading is a more or less exact replication of words on paper without the use of any nonverbal interpretation. Speaking, as you will realize if you think about excellent speakers you have seen and heard, provides a more animated message.

Methods of Presentation Delivery

There are four methods of delivery that can help you balance between too much and too little formality when giving a presentation.

Impromptu Speaking

Impromptu speaking is the presentation of a short message without advance preparation. You have probably done impromptu speaking many times in informal, conversational settings. Self-introductions in group settings are examples of impromptu speaking: “Hi, my name is Steve, and I’m an account manager.” Another example of impromptu presenting occurs when you answer a question such as, “What did you think of the report?” Your response has not been preplanned, and you are constructing your arguments and points as you speak. Even worse, you might find yourself going into a meeting and your boss says, “I want you to talk about the last stage of the project. . . “ and you had no warning.

The advantage of this kind of speaking is that it’s spontaneous and responsive in an animated group context. The disadvantage is that the speaker is given little or no time to contemplate the central theme of his or her message. As a result, the message may be disorganized and difficult for listeners to follow.

Here is a step-by-step guide that may be useful if you are called upon to give an impromptu presentation in public:

• Take a moment to collect your thoughts and plan the main point you want to make.
• Thank the person for inviting you to speak. Avoid making comments about being unprepared, called upon at the last moment, on the spot, or feeling uneasy.
• Deliver your message, making your main point as briefly as you can while still covering it adequately and at a pace your listeners can follow.
• If you can use a structure, using numbers if possible: “Two main reasons . . .” or “Three parts of our plan. . .” or “Two side effects of this drug. . .” Timeline structures are also effective, such as “past, present, and future or East Coast, Midwest, and West Coast”.
• Thank the person again for the opportunity to speak.
• Stop talking (it is easy to “ramble on” when you don’t have something prepared). If in front of an audience, don’t keep talking as you move back to your seat.

Impromptu presentations:  the presentation of a short message without advance preparation . Impromptu presentations are generally most successful when they are brief and focus on a single point.

For additional advice on impromptu speaking, watch the following 4 minute video from Toastmasters: Impromptu Speaking

Manuscript Presentations

Manuscript presentations  are the word-for-word iteration of a written message . In a manuscript presentation, the speaker maintains their attention on the printed page except when using visual aids. The advantage of reading from a manuscript is the exact repetition of original words. In some circumstances this can be extremely important. For example, reading a statement about your organization’s legal responsibilities to customers may require that the original words be exact.

A manuscript presentation may be appropriate at a more formal affair (like a report to shareholders), when your presentation must be said exactly as written in order to convey the proper emotion or decorum the situation deserves.

However, there are costs involved in manuscript presentations. First, it’s typically an uninteresting way to present. Unless the presenter has rehearsed the reading as a complete performance animated with vocal expression and gestures, the presentation tends to be dull. Keeping one’s eyes glued to the script prevents eye contact with the audience. For this kind of “straight” manuscript presentation to hold audience attention, the audience must be already interested in the message and presenter before the delivery begins.

It is worth noting that professional speakers, actors, news reporters, and politicians often read from an autocue device, commonly called a teleprompter, especially when appearing on television, where eye contact with the camera is crucial. With practice, a presenter can achieve a conversational tone and give the impression of speaking extemporaneously and maintaining eye contact while using an autocue device. However, success in this medium depends on two factors: (1) the presenter is already an accomplished public speaker who has learned to use a conversational tone while delivering a prepared script, and (2) the presentation is written in a style that sounds conversational and in spoken rather than written, edited English.

Extemporaneous Presentations

Extemporaneous presentations  are carefully planned and rehearsed presentations, delivered in a conversational manner using brief notes . By using notes rather than a full manuscript, the extemporaneous presenter can establish and maintain eye contact with the audience and assess how well they are understanding the presentation as it progresses. Without all the words on the page to read, you have little choice but to look up and make eye contact with your audience.

Watch the following 10 minute video of a champion speaker presenting his extemporaneous speech: 2017 International Extemporaneous Speaking National Champion — Connor Rothschild Speech

Presenting extemporaneously has some advantages. It promotes the likelihood that you, the speaker, will be perceived as knowledgeable and credible since you know the speech well  enough that you don’t need to read it. In addition, your audience is likely to pay better attention to the message because it is engaging both verbally and nonverbally. It also allows flexibility; you are working from the strong foundation of an outline, but if you need to delete, add, or rephrase something at the last minute or to adapt to your audience, you can do so.

The disadvantage of extemporaneous presentations is that it in some cases it does not allow for the verbal and the nonverbal preparation that are almost always required for a good speech.

Adequate preparation cannot be achieved the day before you’re scheduled to present, so be aware that if you want to present a credibly delivered speech, you will need to practice many times. Because extemporaneous presenting is the style used in the great majority of business presentation situations, most of the information in the subsequent sections of this chapter is targeted toward this kind of speaking.

Memorized Speaking

Memorized speakin g is the recitation of a written message that the speaker has committed to memory. Actors , of course, recite from memory whenever they perform from a script in a stage play, television program, or movie scene. When it comes to speeches, memorization can be useful when the message needs to be exact and the speaker doesn’t want to be confined by notes.

The advantage to memorization is that it enables the speaker to maintain eye contact with the audience throughout the speech. Being free of notes means that you can move freely around the stage and use your hands to make gestures. If your speech uses visual aids, this freedom is even more of an advantage. However, there are some real and potential costs.

First, unless you also plan and memorize every vocal cue (the subtle but meaningful variations in speech delivery, which can include the use of pitch, tone, volume, and pace), gesture, and facial expression, your presentation will be flat and uninteresting, and even the most fascinating topic will suffer. Second, if you lose your place and start trying to ad lib, the contrast in your style of delivery will alert your audience that something is wrong. More frighteningly, if you go completely blank during the presentation, it will be extremely difficult to find your place and keep going. Obviously, memorizing a typical seven-minute presentation takes a great deal of time and effort, and if you aren’t used to memorizing, it is very difficult to pull off. Realistically, you probably will not have the time necessary to give a completely memorized speech. However, if you practice adequately, your approach will still feel like you are being extemporaneous.

What is Oral Communication?

Oral communication is transfer of information from sender to receiver by means of verbal and visual aid. Examples of oral communication include presentations, speeches, discussions, etc.

Though the message is conveyed through words, most of the times oral communication is effectively carried out with the help of non-verbal communication like body language and tone modulations. Oral communication is also at times mixed with visual aid to help establish the conveyed message in a clear manner.

Oral Communication Examples include usage of presentations in a seminar or meeting to put across the message in a clear manner. Oral communication can also be mixed with written communication methods to ensure that maximum effectiveness is achieved.

Oral Communication Definition

Oral communication takes place in face-to-face conversations, group discussions, telephone calls and other circumstances in which spoken word is used to express meaning. Ricky W. Griffin

Oral communication takes place when spoken words are used to transfer information and understanding form on person to another. S. K. Kapur

Modes of Oral Communication

Research studies have shown that 80% of communication by executives of a company is in the oral form. The modes of Oral Communication include:

• Telephone/Cellular phone • Messages • Intercom • Face-to-face discussion • Meetings/Conferences • Presentation • Dictaphone/Dictation • Conversation • Radio • Teleconferencing • Speeches • Brainstorming sessions • Grapevine • Interview

Advantages of Oral Communication

Advantages of oral communication are mentioned below:

Immediate Feedback

Time saving, personal touch, flexibility, group communication, effectiveness, persuasive power.

The biggest advantage of oral communication is that it provides immediate feedback to both the sender and the receiver. Each can therefore ask for clarification and elaboration on the spot.

The speaker can immediately understand the reaction of the audience or group, s/he is addressing while the hearers get a number of clues about how their behaviour is being perceived by the speaker.

Oral communication is very fast. It saves the time involved in writing the message and delivering it through a channel like the postal or courier services.

Oral communication saves the money spent on stationery and the channel of communication.

Oral communication builds up a healthy climate in the organization by bringing superiors and subordinates closer. It is also an effective tool for persuasion.

Oral communication provides an opportunity to the speaker to correct himself and make himself clear by changing his voice, pitch, tone, etc. A number of other factors like context, body language, etc. can be used to reinforce and modify what is spoken through the words.

Oral messages can be more easily kept confidential than written messages. All one has to do is to ensure that there is no one within the hearing or recording distance.

Oral communication is extremely useful for communicating with groups in meetings, conferences, etc. No classroom teaching would be possible without oral communication.

Because oral communication involves the real or virtual presence of both the parties, therefore, the message transfer is more effective and that helps in achieving the goal of the communication more efficiently.

Persuasion is the process of guiding people toward the adoption of an idea, attitude or action by rational means. It relies on “appeals” and convincing arguments. We live in a world where persuasive oral messages are around us.

Disadvantages of Oral Communication

Disadvantages of oral communication are explained below:

Poor Retention

Time consuming, misunderstanding, lengthy messages, lack of responsibility.

The listener cannot retain oral messages in his memory for a long time. The speaker himself may not recall what he actually said.

Oral communication does not provide any record for future reference. In the absence of a record, oral messages have no legal validity.

Oral communication may not always be time saving. Precisely because there is no binding medium like a page or a book, this form of communication is virtually endless. Sometimes meetings continue for a long time without arriving at any satisfactory conclusion.

Oral communications are likely to be misunderstood due to poor expression and noise. The speaker may not be able to make himself quite clear or the listener may be inattentive. This is likely to be truer when the two individuals are not on good terms with each other.

Oral communication is not suitable for transmitting lengthy messages. Some parts of vital importance may not receive adequate attention.

Oral messages are not recorded. Therefore, it becomes difficult to hold persons responsible for mistakes, inaccuracy or falsity in oral communication.

People usually take less care when speaking than when writing. Therefore, spoken words tend to be less precise than written words. Often the exact point the speaker is trying to make is lost in a mass of words.

How to Make Oral Communication Effective?

The following steps should be taken to make oral communication effective :

Right words

Avoid hackneyed phrases, understand the listener, natural voice, logical sequence.

The speaker should pronounce his words “clearly” and “correctly”. He must talk distinctly and slowly. When a person speaks fast or munches words the oral message is likely to be misunderstood.

The way a person speaks his dialogue exercises much influence on the audience. Clarity of expression is the aim at all times.

Oral communications often suffer from too much of talking. When a speaker keeps on talking for long, his message is lost in a sea of words and his listeners tend to become inattentive.

Therefore, the message must be kept as short as possible. However, the speaker should not appear unclear, abrupt or discourteous.

An oral message becomes more effective when it is precise and concise.

Example : It is better to say ‘cut down costs by 100 instead of saying ‘reduce costs’. The message should not be vague or incomplete. Words ought to mean clearly what they are intended to say.

The first caution is to ensure that you know the meaning of the words that you use. Some words have more than one meaning while some others carry different meanings for different persons. Be sure about what your words will convey to a trained reader. Example : City, town and metropolis are three different words and care should be exercised before using them. You will find that the word ‘metro’ has at least three different meanings in day-to-day usage. Find them out for yourself. Therefore, words should be chosen carefully and their meaning clarified in the context of usage. The speaker should not presume that the listener would mean the same thing from a word, which s/he means.

Speakers often use hackneyed phrases and clichés like ‘you know’, ‘I see’, ‘you see’, ‘what I mean’, ‘isn’t,’ etc. Such phrases interrupt the flow of speech and obstruct the quick grasp of meaning besides causing boredom. Speakers should ensure that they do not use these phrases unconsciously or consciously. Most of us use them as connectives, filling up a gap when we do not have the correct word/phrase. Keeping them consciously out of your usage would mean that you will have to remain silent for those gaps. But don’t worry. Once you stop using fillers like those, appropriate words will come to you with a little effort at articulation.

A good speaker must understand the listener before talking. People vary in terms of their education, culture, intelligence level, maturity, etc.

The speaker should use his natural way of speaking. In order to look sophisticated, some speakers use a foreign accent. This reduces the effectiveness of communication.

Before speaking, different ideas to be conveyed should be arranged in a logical order. It helps to make the speech forceful.

A speaker must have conviction in what he says. Careful understanding, the sincerity of speech, and intelligent planning are required to develop conviction in speech.

Importance of Oral Communication

The importance of oral communication can be discussed in the following points:

Importance for a scholar

Importance for a professional, importance for business, as a marketing tool.

The art of oral presentation is of immense significance for an academician or a student who is needed to defend his/her thesis in a seminar or a conference.

At times, managers or executives in a company are required to prepare a report and then give an oral presentation on that report. Their performance can make or mar their career.

Oral communication are of huge significance in today’s business environment. It’s simply because nothing has more impact, or is quite as impressive, as a well-delivered oral presentation.

Properly executed and in the right context, they can inform, motivate and convince more effectively than any other single form of communication. As a result, employers place great value on presentation skills.

Ability to deliver oral presentation is one of the most effective tools of marketing. For instance, consider these two typical situations where oral presentation skill will be needed as a marketing strategy:

Go to Section:

What is Oral Communication | Oral Communication Definition | Modes of Oral Communication | Advantages of Oral Communication | Disadvantages of Oral Communication | How to Make Oral Communication Effective | Importance of Oral Communication | Principles of Oral Communication |

Principles of Oral Communication

The following are the main principles of oral communication :

Source of information

Consistency, principle of time, balance between uniformly and adaptability, emotional appeal, consultation, selection of main idea, introduction, researching the topic.

In oral communication the meaning of the words and the language should be clear so that the audience does not misunderstand it. One should avoid the use of technical, very difficult or literary words.

The communication should be simple so that every type of audience finds it easy to understand.

The sources of information used in the communication should be reliable and the audience should be informed about the source to increase their confidence.

The quantity, weightage, expansion and the subject matter should be decided in a wise manner, communication that are lengthy, too detailed and difficult are boring. Over abundance of information puts strain on the mental ability. Thinking and working of the audience.

The figures and information used in the communication should not be in conflict with the policies, objectives and programmes of the institutions.

The communication should not take more time that intended. Principle of time leaves a good impression on the audience.

On the one hand uniformity of message in the communication should be attempted and on the other due importance should be given to the changer in today’s fast business. In other words one should try to strike a balance between uniformity and changeability or adaptability of words. h. Principle of Audience Analysis

To develop a mutual understanding with the audience and to remove the unnecessary difficulty of meanings the presenter should keep in mind the age, education, ability, knowledge and organizational position of the audience.

In some communication there is a lack of logic and intellect therefore there should be an emotional appeal in the communication so that a positive response can be taken from the audience.

To make a communication effective the communicator should consult all the related people. This way one can get some new advice and ideas.

After communication the communicator should try to find the views, Ideas, opinions, objections and feelings of the audience. This develops an understanding between the two and the objective of communication is also fulfilled.

In the communicator mind the purpose of the communication should be absolutely clear and defined. Objectives could be one or more. The purpose of the communication could be to inform, encourage, sympathies and entertain.

The communicator should put himself in the place of audience while doing the communication. This brings about a similar opinion and creator mutual understanding.

Before communication one should rehearsal atleast thrice. This increases self confidence and makes the communication easier.

The main idea or should be decided before hand. This makes the communication easier and interesting.

It is said that first impression is the best impression. Thus, the communicator should introduce the communication with expertise, patience, cleverness and effectively that the audience can connect to it right till the end.

A friendly behaviour should be used with the audience. As a result he can say opinion with ease and the audience too will accept it.

Information, figures and other facts related to the communication should be collected so that some new ideas can be joined with the basic thought that is change should be acceptable.

At the end of the communication the main points should be revised which make the audience will remember the basic thought of the communication

PAIBOC Model

PAIBOC is an acronym devised by Kitty Locker and Stephen Kaczmarek. The PAIBOC model can be an instrumental tool for effective communication, specifically with speeches. PAIBOC refers to purpose, audience, information, benefits, objections and context. In an organisation, it is important to have a set process when initiating any business correspondence. PAIBOC is explained as follows:

It stands for purpose, which infers the purpose for initiating communication or writing a document. For example, the credit card division of a bank decides to send a formal e-mail to its credit card holders to make them understand the policy of moratorium period during Covid-19 Pandemic.

The purpose of the communication in this case is to educate its customers on the responsible use of credit cards and to use debt responsibly.

It stands for an audience, which explains who is the target audience or recipient of the communication. Having an insight into the target audience is cardinal for the success of communication. For instance, the target audience of communication via e-mail is the credit cardholders.

It stands for information, which infers what information the message should contain. The information that is shared relies on the audience. If the audience is not aware, then they need to be familiarised with facts.

For instance, the E-mail would involve information about the relaxation provided during the moratorium period; consequences of irresponsible use of credit; ways to manage credit/debt; and reasonable expectations of the use of credit.

It stands for benefits, what benefit both the sender and the receiver will derive from the exchange of communication.

For example, assessing how much interest they need to pay on the credit taken, how much interest customers have to pay during and after the moratorium period. In such a case, the bank can ensure that its customers are aware about the relaxation period and time limit to which they have to pay the bill.

It stands for objections, what objections can be raised by the receiver and how to overcome those objections tactfully. For instance, credit card holders can raise requests to extend the moratorium period in order to pay less interest on a credit card.

It stands for context, which refers to what is the relationship with the receiver. Context can also relate to morale in the organisation, the economy, the time of year and any special situation.

For instance, a formal e-mail can exchange important information with the customers and they will be more aware about the payment policy and procedure.

Disadvantages of visual communication 

1. Inability to Convey Emotion: Visual communication can be limited in its ability to convey emotions or tone of voice, which can be important in certain contexts. For example, written communication can be difficult to interpret without understanding the writer’s intent or tone of voice, and visual aids may not be able to convey this information accurately. Similarly, some people may be more comfortable expressing themselves orally, making visual communication less effective in these situations.

2. Limited Accessibility: One of the main disadvantages of visual communication is that it may not be accessible to people with certain disabilities.  For example, Individuals having visual impairments will not be able to view or understand the visual message. Hence oral communication would be more suitable in these kinds of situations.  

3. Misinterpretation: Visual communication can be subject to misinterpretation, as individuals may interpret visuals differently. In addition, It can be difficult to convey complex ideas or information using visual aids alone, which can lead to confusion or misunderstandings. This is particularly true when the visual aids are not well designed or organized, or when they are used in isolation from other forms of communication like oral or written communication . 

4. Cultural Differences: Visuals may not be universally understood across different cultures. Symbols and images may have different meanings in different cultures, leading to misunderstandings and miscommunications.

5. Cost: Creating high-quality visuals can be costly and time-consuming, especially for businesses and organizations with limited resources.

6. Issue of Technological constraints: There may be certain technical limitations that could constrain the use of certain visuals. For example, some websites may not be able to display high-quality images or videos due to bandwidth limitations. In addition, technical constraints may also arise due to hardware and software limitations. Some older devices may not be compatible with certain image or video formats, which could affect the quality of the visuals. 

7. Inaccurate Representations: Visuals may not always accurately represent the information they are intended to convey. This can happen because of problems such as data inaccuracies or biases which may lead to misleading conclusions. 

8. Information Overload: Visual communication can also contribute to information overload. If too many visuals are used or if they are too complex, viewers may become overwhelmed and have difficulty processing the information.

9. Reliance on Technology: The use of technology plays a significant role in visual communication and it can be vulnerable to technical glitches and issues. This can disrupt communication and lead to frustration for viewers.

10. Ineffective for Certain Types of Information: Visual communication may not be the most effective way to convey certain types of information. For example, abstract concepts may be difficult to represent visually. Offen time complex or technical information may require written or oral communication to fully explain.

11. Restricted Interaction: Visual communication may offer limited opportunities for interactivity compared to other forms of communication, such as written or verbal communication. This can limit the ability of viewers to ask questions or engage with the information presented. 

12. Limited Persuasiveness: Visual communication may not be as persuasive as other forms of communication. While visual aids can be persuasive and influential in some situations, they may not have the same impact as oral or written communication, particularly when it comes to more complex or nuanced arguments. This can be a big disadvantage of visual communication in situations where persuasion is important, such as in sales or marketing.

Lack of Personal Connection: Visual communication can lack a personal connection between the communicator and the audience, particularly when compared to oral communication. This can be a disadvantage in situations where building trust and rapport is important, such as in interpersonal relationships or business negotiations.

Examples of visual communication

Visual communication can take many different forms and can be used in a variety of contexts. Here are some examples of visual communication:

1. Infographics: These are graphical representations of information or data that are designed to make complex information more easily understood.

2. Charts and graphs: Charts or graphs are graphical illustrations utilized to communicate patterns or connections within data or information.

3. Photographs: Photographs can be used to capture a moment or convey a mood or emotion.

4. Videos: Videos can be used to tell a story, demonstrate a process, or convey information.

5. Illustrations: Illustrations can be used to create a visual representation of an idea, concept, or story.

6. Logos and branding: Logos and branding can be used to visually represent a company or organization.

7. Signage: Signage can be used to convey information, such as directions or warnings, in a visual format.

10. Packaging design: Packaging design incorporates visual elements, such as color and graphics, to create a product’s visual identity.

What is the importance of visual communication? 

Effective transmission of information and messages heavily relies on visual communication. By using visuals, we can help audiences to comprehend information more easily, making it more likely that they will engage with and remember the message. Here are some key reasons why visual communication is important: 

Firstly, visual communication can simplify complex ideas and make them easier to understand. They provide a quick and easy way to convey information and help the audience remember the message.

In addition, visual communication possesses a broad-based appeal that surpasses linguistic and cultural obstacles , making them an efficient channel for connecting with a vast audience. 

Secondly, visual communication can evoke emotions and create a strong emotional impact. Images and videos have the power to elicit feelings and emotions in a way that text alone cannot. Creating an emotional bond of this nature can aid in developing confidence and cultivating a stronger relationship with the audience.

Lastly, visual communication can help businesses to improve the user experience by creating brand identity and recognition, making it easier for audiences to identify and remember a brand.

In summary, the importance of visual communication lies in its ability to simplify complex ideas, evoke emotions, and improve the overall user experience. It has become an essential tool for effective communication in a world where attention spans are short and information overload is prevalent.

Advantages and disadvantages of visual information

Visual information, such as images, videos, and infographics, has become increasingly prevalent in modern communication. However, like any other form of information, visual information has its own set of benefits and limitations.

Advantages of visual information

Improved comprehension and retention of information : Studies have shown that people remember visual information better than text alone, making it a valuable tool for communicating important information. By using visuals to break down complex ideas into digestible parts, we can help audiences to comprehend information more easily and retain it for longer periods of time.

Increased brand awareness and recognition: Visuals are an important tool for establishing brand identity and recognition. By using consistent visual elements such as logos, color schemes, and typography, businesses can create a distinct brand identity that is easily recognizable. 

Improved accessibility: Visual information can be a more accessible way of conveying information for people with learning disabilities, as it can simplify complex ideas and make them more understandable. For example, infographics can help to convey information that may be difficult to understand in a traditional text-based format. 

Disadvantages of visual information 

High chance of misinterpretation: One disadvantage of visual information is that it can sometimes be misinterpreted or misunderstood. For example, a chart or graph may be interpreted in different ways depending on the audience’s background knowledge or perspective. This can lead to confusion or miscommunication. 

Can be costly: Another disadvantage of visual information is that it can be time-consuming and expensive to create. High-quality visual information requires significant planning, design, and production time, which can be a challenge for organizations with limited resources. 

Advantages and disadvantages of visual symbols

Visual symbols are a form of visual communication that use images or icons to represent ideas, concepts, or objects. Like any form of communication, visual symbols have both advantages and disadvantages.

The Advantage of visual symbols: 

One of the main advantages of visual symbols is that they can be easily understood across different cultures and languages. Visual symbols can be universally recognized and do not require translation, making them a powerful tool for global communication. Additionally, visual symbols can convey complex ideas or concepts in a simple and memorable way, making them an effective tool for advertising and branding.

The disadvantage of visual symbols: 

Visual symbols can be open to misinterpretation or ambiguity. Different people may interpret the same symbol in different ways, based on their background, cultural context, or personal experiences. This can lead to confusion or miscommunication, particularly if the symbol is used in a critical or sensitive context.

Advantages and disadvantages of audio-visual communication

Audio-visual communication refers to the use of audio and visual aids such as videos, animations, and presentations to convey information. However audio-visual communication has its importance and limitations.

Advantages of audio-visual communication:

• Increases audience engagement and interest.
• Helps convey complex information more effectively.
• Appeals to different learning styles.
• It is possible to utilize audio-visual communication to elicit emotions and generate a more memorable encounter.
• Can be more effective in delivering messages compared to text-only communication.

• Enables real-time communication and feedback.
• Can be more efficient and cost-effective than in-person communication.

Disadvantages of audio-visual communication:

• Requires technical skills and equipment.
• Technical problems such as equipment failure or poor internet connectivity can have a negative impact.
• May not be accessible to individuals with hearing or visual impairments.
• May not be as effective in conveying complex or nuanced information as text-only communication.
• Can be time-consuming to produce and edit.
• Can be costly to produce high-quality audio-visual content.
• In many situations, it can be difficult to measure the effectiveness of audio-visual communication.
• May require additional resources for translation or localization.
• May not be appropriate for all audiences or contexts.
• Can be affected by cultural differences or misunderstandings.

What are the effects of visual communication? 

Visual communication is a strong channel of communication that produces significant impacts on individuals and the entire society. One of the primary effects of visual communication is that it captures the audience’s attention and engages them.

By using a combination of design elements, such as color, typography, and imagery, visual communication can create a captivating experience that draws people in.

Another effect of visual communication is that it can also shape people’s perceptions and attitudes toward different ideas or products. By using various design elements and messaging, visual communication can create a specific brand image or evoke a certain emotion.  

Finally, visual communication can have a significant impact on society as a whole. It can be used to create awareness around important issues, shape public opinion, and promote social change. By using visual communication effectively, individuals and organizations can bring attention to important social issues and promote positive change.

How can visual communication be improved? 

Visual communication can be improved in several ways. Here are some tips to enhance the effectiveness of visual communication:

1. Understand the target audience: Before creating any visual communication, it is essential to understand the target audience’s needs, preferences, and expectations. This will help create visuals that resonate with them and improve engagement.

2. Simplify the message: Visual communication should be simple and easy to understand. Complex visuals can be confusing and turn off the audience. Simplifying the message ensures that the audience gets the point quickly.

3. Use clear and concise visuals: The visual elements should be clear, concise, and easy to read. Avoid using too many design elements or cluttered visuals that can confuse or overwhelm the audience.

4 Focus on the purpose: Visual communication should be created with a specific purpose in mind. The visual should be designed to achieve a specific goal, such as promoting a product or raising awareness for a cause.

5. Incorporate visual hierarchy: Visual hierarchy refers to the arrangement of visual elements in a way that guides the audience’s attention. Using a visual hierarchy ensures that the most critical information is highlighted and stands out.

Advantages Of PowerPoint

PowerPoint is available for both Windows and macOS , as well as for mobile devices running iOS and Android. This makes it a convenient tool for creating presentations, regardless of what type of device you are using. You can also use PowerPoint for the Web in a web browser, making it even more accessible. Not a lot of presentation software offers such flexibility.

PowerPoint is the most feature-rich presentation software out there. It has everything you need to create a professional-looking presentation, including built-in templates, themes, and much more. Other presentation software simply cannot compete with PowerPoint in this regard.

PowerPoint is the most widely used presentation software, and it’s the industry standard tool for preparing presentations. People are generally familiar with how PowerPoint works, which makes it easy to use when giving presentations. It is also the most compatible presentation software , meaning that it can be opened and viewed on just about any device.

PowerPoint comes with a variety of built-in themes and templates that you can use to make your presentation look more professional. If you’re not a design expert, these templates can be a lifesaver. With just a few clicks, you can make your presentation look great without spending hours on design.

The interface of PowerPoint is also quite versatile. You can easily access all the needed features by using the toolbar options. Its interface is also customizable , so you can change it to suit your needs better.

PowerPoint is relatively easy to use , even if you’ve never used it before. Of course, it takes some time to learn all the features and how to use them effectively. However, you should be able to start creating basic presentations without much trouble.

You can open and edit presentations saved in various formats with PowerPoint. Some of the supported formats include pptx, ppt, gif, mp4, jpeg , and more. This is a convenient feature if you need to import or export presentations in variable programs. Other presentation software supports only a limited number of formats.

PowerPoint also integrates smoothly with other Microsoft Office programs, such as Word and Excel. This makes it easy to create presentations that include data from other Office programs. Moreover, PowerPoint files are supported by most online storage services, such as Google Drive and Dropbox, for seamless sharing.

PowerPoint also supports add-ins , which are small programs that add additional features to the software. There are a large number of add-ins available for PowerPoint that you can use to customize your presentations further.

PowerPoint makes it relatively easy to collaborate with others on a presentation. You can easily share your presentation with others and allow them to view it or make changes by sharing a link. This is a convenient feature if you are working on a team project.

PowerPoint is also available in a mobile version , which allows you to create and edit presentations on the go. You can download the PowerPoint app for free from the App Store or Google Play to use on iOS or Android devices. This is a handy feature if you need to make last-minute changes to your presentation.

One of the features of the PowerPoint software that most users find useful is the password protection feature. This allows you to set a password for your presentation so that only those who know the password can open and view it. Most other presentation software does not include this component.

Disadvantages of PowerPoint

Now that we’ve looked at the advantages of PowerPoint, let’s take a look at some of its disadvantages:

It’s been around three decades since PowerPoint was first released, and in that time, it hasn’t seen a whole lot of innovation. This lack of innovation can make it feel dated compared to some of the newer presentation software options on the market. Some users find PowerPoint slides boring, as there is not much scope to create creative or interactive presentations.

The features and tools of PowerPoint can be a bit complex to learn , especially if you’ve never used the software before. It can take some time to get a grasp on how to use all the features effectively. And if you want to create more complex presentations, it may take even longer.

PowerPoint can also have some performance issues, especially on weak systems. The software can be a bit resource-intensive, so it may run slowly on older computers . Additionally, large or complex presentations may take longer to load and may not run as smoothly as you’d like.

If you want to purchase PowerPoint outright, it’s relatively expensive compared to some of the other presentation software options on the market. Google Slides offers many of the same features as PowerPoint, but it’s free to use.

PowerPoint is a widely used presentation software that is available for all major operating systems. It offers a large number of features and is widely accepted.  However, it can be a bit complex to learn and is relatively expensive. Despite these disadvantages, PowerPoint is still a popular choice for creating presentations.

Top 7 Slides on Communication Skills- Free PPT

Think of flying back to a time when humans lived in caves and conveyed their thoughts, feelings, and expressions through incredible artwork on the walls of these caves. Since they lacked a written language, they communicated ideas and told tales through these paintings.

But have you noticed one thing? If not, let me tell you.

People's ability to interact has been vital throughout history as they have discovered distinct methods to connect and share from pre-historic cave drawings.

As we think about how important communication is over time, it's essential to think about how we can get better at communicating in today's world.

So, let’s discuss some essential aspects to be kept in mind to enhance communication skills:

• Clear and concise: It is important to note that while interacting with others, one needs to express their thoughts clearly and in a simple, short way so the listener does not get confused.
• Body Postures and Facial expression: Despite being transparent, one needs to express their words and non-verbal language, i.e., through gestures.
• Good Listener: One must be open-minded while hearing others to improve communication skills. Apart from that, one must be open enough to adapt to those new ideas and perspectives.
• Provide remedies and resolve issues: Despite being a good listener, one needs to be open enough to present their views on the ongoing problems so that they are solved without having any deep impact within a firm or interpersonal relationships.

As we have discussed, certain aspects are required to enhance communication skills; let me share something with you! SlideTeam has prepared a customizable PowerPoint presentation on communication skills to improve the firm's productivity significantly.
