Concept formation: abstraction of feature set (e. g. child acquires representation of concept apple") Concept learning: applying concept (e. g. child learns that/why tomato is not an apple) 4 cognitive processes: becoming symbolically familiar with a concept, formation of underlying mental representation, selecting: what concept fits current situation, distinguishing between different concepts. Terminology: concept: set of objects with family resemblance", mental representation of (1) Tied to group of objects in the world sparrow-1, sparrow-2, sparrow-3, robin-1, finch-1, owl-1, etc cf. concept bird = sparrow-1, sparrow--2, etc: mental representation of 1, classification system. Definition of bird based on conventions or decision rules. Category is represented by a series of necessary and sufficient features; Consequence: "hard" boundaries between classes e. g. a cup is not a vase, because it has an ear (defining feature) Flaws: categorisation would require perfect match between object and definition some objects are more typical members than others and these are acquired and recognized faster.
