Are your presentations dry and unmemorable? Could you combine multiple slides to convey your message more succinctly? Could any of the words in your presentation be better illustrated as pictures?Cognitive psychologist Richard Mayer has explored the relationship between multimedia and learning. Multi-sensory environments lead to more accurate recall that lasts longer. From Mayer's findings, here are five rules you can use to enhance recall and retention in your audience:1) Present words and pictures together, not words alone2) Locate words and pictures near each other, instead of spaced apart3) Combine related words and pictures into one slide, rather than using multiple4) Exclude extraneous material5) Complement animations with narration, instead of on-screen textApplying these simple principles will create a strong foundation upon which you can build, stand out and be remembered.
