Document Summary
How brain stores info & organizes info. Concepts & categories: concept: mental representation of idea, categories: clusters related concepts. Categorization: form categories: classical categorization: theory claims objects/events categorized by certain rule/feature set. E. g. shapes: graded membership: some concepts better category members than others. Sentence-verification technique: some category members recognized faster. E. g. sparrow faster than penguin as bird. Best examples (prototypes) affect categorization: prototype: mental representation of typical category member. E. g. ostriches dissimilar from rest of birds: classical categorization vs. prototype. If complications, use classical categorization: networks & hierarchies: Semantic network: interconnected set of concepts (nodes), links joining them = category. Links = join concepts, represent category structure & relationships. How concepts arranged semantic networks affects rate of info access about them. Priming: activation of individual concepts in ltm. Rxn time measurements lexical decision task. Memory, culture, categories: role of experience in ability organize info. Recently exposed to example from 1 category biased diagnosing new cases.
