Do we Need to Forget in Order to Remember?

Having a "good mind" usually connotes the ability to stuff one's brain with memories, from useless details to important ideas, and to be able to retrieve them on cue. To help out, most of us formulate mnemonics to make ideas difficult to forget.But what if forgetting is key to the proocess of remembering?

Several years ago, neuroscientists found that the brain is able to predict which memorie will be important later, ultimately affecting the volume of retention. Further research suggested that dreaming erases our useless memories to make space for new and more relevant ones.

A recent study allowed researchers to test whether the brain benefitted from eliminating irrelevant thooughts. Participants memorized word pairs and were then asked to retrieve only some of them when prompted. Those who forgot more of the irrelevant word pairs were better able to retrieve the relevant pairs when prompted. Keep dreaming!
