Document Summary
Knowledge: information or skills acquired through experience. Includes identifying features, classifying, making decisions, problem solving, reasoning. Concept: mental representation of categories arranged hierarchically. Category: certain groups themselves objects have something in common. Token: particular instance (ex. a specific chair) Recognition = classification of an object into a category by automatically identifying features. Organization and cognitive economy categorization makes it easier to remember things. Classification decreases the amount of info we need to learn, perceive and remember. Allow us to infer and predict ambiguous stimuli (ex. emotions in a face) We use concepts to communicate and convey info. Formal concepts: defined by common essential characteristics with no ambiguity. Natural concepts: defined by person" perceptions and interpretation for the world. Leads to distributed activity based in different properties of object (ex. shape, colour, motion, texture, behavioural properties) Category-specific deficit: can"t identity objects that belong to a certain category (ex. animals)
