Appeal to Different Ways of Learning
The ear is a very poor information gathering device. Typically listeners only retain only a small fraction of what is explained to them verbally. The first way to enhance retention is to appeal to as many of the senses as possible. Studies show that audiences retain 20 percent of what they hear, 30 percent of what they see, and 50 percent of what they hear and see (9). When the audience has an opportunity to do something (adding the kinesthetic sense), their retention increases to 80 percent (22). Or, if participation is not possible, a handout will raise retention to an impressive 85 percent—if the audience can review the handout at least once (25).
Another way to help your listeners remember is by the use of techniques like association, linking the new topic to things that the audience knows about or already understands. If you were giving a speech about rugby, you might compare it to soccer and football to help the audience understand the rules. The use of acronyms also aids retention. On the “Krusty Krab Training Video” episode of Spongebob Squarepants (a spoof on corporate training videos), they use the acronym “POOP.” When I asked my eight year old son if he knew what “POOP” stood for, he immediately and correctly answered “People Order Our Patties.” The final technique to help audiences remember information is the simplicity criterion. Information is best retained when it is explained from top to bottom (rather than bottom to top), when events are presented from first to last (rather than last to first), and when information is presented in the positive voice (rather than in the negative voice) (26).
