Useful Research for Crafting Presentations

1.

There are two information-processing channels that we use: visual and verbal. We can only process so much information through these channels at a given time. Learning requires substantial processing, so understanding how to balance information to these channels is critical for a successful presentation.

Research shows that people understand a multimedia presentation better when pictures are accompanied by narration, rather than by text on a slide. This suggests presenters may be more successful using highly visual slides and communicating the information verbally, rather than by reading written text on a slide.

3.

It's generally accepted that we can hold three to four chunks of information in our working memories at a time. Having no more than three to four main sections for our talks will better resonate with the audience's working memory capacity.

"Distributed learning, in certain situations, can double the amount we remember later on. This means when possible, spacing out the amount of information we give to audiences, rather than fitting it in one class or session, will help our audience learn the information."

Quote from Benedict Carey, How We Learn

5.

"If information is presented orally, people remember about 10%, tested 72 hours after exposure. That figure goes up to 65% if you add a picture."

So, pictures are a powerful memory tool.

Quote from John Medina, Brain Rules

6.

In case you weren't convinced by number 5, with study your recall of pictures increases over time, while your recall of words actually declines.

7.

We perform best when we're in an environment similar to the one where we prepared or studied. So, practicing a presentation in a way that mimics the actual event could help boost performance for the presentation.

8.

Just like facing any other fear, it matters how we control our anxiety and stress prior to giving a talk. While some stress can improve performance, too much will be detrimental to a presentation. Try to use breathing and meditative exercises whenever you feel nervous or anxious about an upcoming talk.
