Document Summary
Chapter 9: knowledge concept: a mental representation that is used for a variety of cognitive functions, including memory, reasoning, and using/understanding language categorization: the process by which things are placed into groups. Comparison approach: decide whether something belongs in a category by comparing it to a standard. To understand cases and situations that we have never seen before. Tool for making inferences about things that belong to a category. To help understand behavior definitional approach to categorization. Decided whether something is a member of a category by determining whether a particular object meets the definition of the category. Problem: not all members of everyday categories have the same features family resemblance. Things in a particular category resemble one another in a number of ways. Instead of setting definite criteria that every member of a category must meet, this allows for some variation within a category categorization through similarity. Prototype approach: the standard is determined by averaging over category members.
