“Using juicy mental images like these is extremely effective. What you want to do is create big, multi-sensory memories,” explains Julia Shaw, a psychological scientist at University College London and the author of The Memory Illusion: Remembering, Forgetting, and the Science of False Memory. You want to aim for mental images that you can almost feel, smell and see, to make them as real as possible.
There’s science behind all of this. “Images that are weird, and maybe gross or emotional are sticky,” says Shaw. “When looking at the brain, researchers found that the amygdala—a part of the brain that is important for processing emotion—encourages other parts of the brain to store memories.” That’s why strong emotions make it more likely that memories will stick.
