Document Summary
**key thing about concepts and categories is that they differ for each person based on their experiences (unique) Categorization - process by which we place things into groups called categories (how we put into groups of cars); helps us learn and organize as well. Category - a class or group of similar things, events, patterns (objects or entities) - (fruits, veggies) Theoretical descriptions of the nature of concepts: 5 types: the classical view, prototype, exemplar, schemata and knowledge-based. Classical view: membership thought to be determined by set of defining properties which are properties that are deemed necessary and sufficient. To consider feature is individually necessary means that each example must have that feature if it is a member of the category (triangles, 3 sided) To say a set of features is collectively sufficient is to say that anything with each feature in the set is automatically an instance of the concept (3 sided and planar is a triangle)
