We will talk about three important rules of the brain that are described in the book Brain Rules by John Medina. Medina is a molecular biologist at the University of Washington. For many years, he has been studying the human brain and some of the data he gathered can be really useful for all of us, ordinary people, who want to make their public appearance a bit better.
So, the first rule is the rule of 10 minutes. Medina used to be a teacher. During this time, he found out an interesting point. After ten minutes of the presentation, the audience begins to perceive the information much worse. People start looking at the clock. They just lose their attention, becoming not so focused on your focused. How can one deal with it? Very simple! You just need to divide your presentation into 10-minute intervals. For example, after 10 minutes, you can show the audience some video or photo. You can slightly deviate from the topic and tell some interesting story that would be connected with the course of your presentation.
The second rule is interest. One should remember that the human brain does not pay attention to the “boring” topics. You risk losing your audience if you present the topic of discussion in a boring way. That is how the human brain is structured, it simply does not perceive boring discussions!
The third rule is the necessity of the visual part. The brain wants to see the picture! As it has been mentioned earlier, perception of the information can vary accordingly to the way it is presented. So, the brain perceives visual images much better than a plain text. A study conducted some time ago insists that people remember about 10% of what is read in 72 hours and 65% of what they had seen when it came to the visual image. In general, use more images in your presentations, because the text … is not so necessary. You are able to talk with the audience by yourself.
