This is Brain Rule #4 in Dr. John Medina’s New York Times Bestselling Book ‘Brain Rules’ – We don’t pay attention to boring things. 
Obvious, right? We think so, but most teachers and learning institutions still teach the majority of their lessons orally without visual stimulation or effective visual stimulation. Medina, a Brain Scientist and Developmental Molecular Biologist, says that anywhere between one third to one half of the brain is devoted to visual processing! Now, you might be thinking that many people use graphs and slides in presentations but Medina says that’s not good enough. He says the brain wants a “rotating, moving, three-dimensional image.”
Watch this interview with him on YouTube to learn more about the significance of visuals in a learning atmosphere.
He also performs an experiment using the McGurk Effect to prove that the more senses involved in a lesson, the more the learner retains. He says, “When multiple senses are stimulated simultaneously, the brain begins to experience an information rich learning experience and laps it up like ice cream. Watch the experiment to see how he demonstrates this point.
Web video uses animated illustrations to engage the viewer and provide them with information that is not only enjoyable to watch and learn, but information that will actually be remembered for longer than a few minutes. In Brain Rules, John Medina writes that, “If information is presented orally, people remember about 10 percent, tested 72 hours after exposure. That figure goes up to 65 percent if you add a picture.”
