The “Production Effect” Aids Memory
The hardest memory task I ever had was to give an 18-minute TED talk from memory. I remember struggling with remembering my core ideas and their sequence. To solve this problem, my first task was to create some slides, which the TED format allows. The directors even show the slides on a monitor at the foot of the stage that only the speaker can see.
