Scientific American Trying to predict a situation impedes memory formation Advertisement Making predictions hinders the brain’s ability to remember the present moment, new research suggests. The hippocampus, a brain structure usually associated with remembering events, also uses experiences to make forecasts (neuroscientists call this “statistical learning”). But scientists writing in the Researchers showed participants a series of photographs on a screen without telling them that some image categories always followed others: mountains always came immediately after beaches, for example. The subjects were intended to subconsciously learn these associations and begin to expect these pairings. Later, the participants were shown the same photos again, mixed in with new examples, and were asked if they had spotted any of them before. They accurately recalled seeing random images at a much better rate than the “predictive” ones (like the beach pictures).
