Document Summary
Concept: mental representation of an object, event, or idea. Categories: clusters of interrelated concepts: smaller, more precise groups, formed using categorization. Classical categorization: theory claims that objects/events are categorized according to a certain set of rules or by a specific set of features: similar to dictionary definitions, ex. Triangle = a figure having 3 angles and 3 sides. Graded membership: observation that some concepts appear to make better category members than others. Prototype: mental representation of an average category member: ex. Semantic network: interconnected set of nodes (concepts) and the links that join them to form a category: nodes represent concepts, links connect these nodes together structure of a category and relationships between categories. Arranged in hierarchy moves from general to very specific. Priming: activation of individual concepts in ltm. Basic-level category: middle row of the diagram: terms used most often in conversation, easiest to pronounce, level at which prototypes exist, level at which most thinking occurs.
