Medical Xpress / Our brains may learn more from rare events than from repetition

More than a century ago, Pavlov trained his dog to associate the sound of a bell with food. Ever since, scientists have assumed the dog learned this through repetition. The more times the dog heard the bell and then got fed, ...
