Document Summary
Concepts: mental representation of an object, event or idea. Categories: clusters of interrelated concepts formed using categorization. Classical organizational: 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 member than others. Psychologists have researched classical categorization using a behavioural measure known as sentence-verification technique. Volunteers wait for a sentence to appear in front of them on a computer screen and respond as fast as they can with a yes or no to statements such as a sparrow is a bird . Prototypes: mental representations of an average category member. Semantic network: an interconnected set of nodes (or concepts) and the links that join them to form a category. Links connect them together to represent the structure of a category as well as the relationships among different categories.
