Cognitive psychologists study cognition, which is the mental activity associated with processing, understanding, and communicating knowledge. To think about the countless events, objects, and people in our world, we organize them into mental groupings called concepts. To simplify things further, we organize concepts into hierarchies. Although we form some concepts by definition, more often we form them by developing prototypes-a best example of a particular category.
