Document Summary
Concept: mental representation of an object, event, or idea. Classical categorization: the earliest approach to the study of categories, is a theory that claims that objects or events are categorized according to a certain set of rules or by a specific set of features. Graded membership: the observation that some concepts appear to make better category members than others. Ie, a sparrow is a bird, but a penguin isn"t (yet it is!) Prototype: a mental representation of an average category member, ie, when someone says bird you would automatically say robin . Semantic network: an interconnecting set of nodes (or concepts) and the links that join them to form a category. Basic-level category: terms used most often, they are the easiest to pronounce, and is the level where prototypes exist. Is based to some extent on cultural learning. Linguistic relativity or the whorfian hypothesis: the theory that the language we use determines how we understand the world.
