categories and concepts Flashcards
Three basic foundations of categorization
Classification, understanding, and communication
Classification
The ability to classify dissimilar objects together in the same group. Example classifying red, green and yellow apple. Dissimilar in colour but they are all apples
Understanding
The ability to evaluate a situation and act properly based on prior experience
communication
The ability to describe complex ideas or objects using a single label. For example furniture, cats, sport
Illusion of the expert
The feeling that a task must be simple for everyone because it is simple for oneself
Protype theory
We categorize objects by comparing them to an internal “best” representation of a given category. Average or best member of a category= prototype; formed through experience
A prototype may not exist in the real world but maybe a hybrid of two different same category things. Prototypes shift constantly
Exemplar theory
We categorize objects by comparing them to every previously stored experience (exemplar) in a given category. You remember every dog you have met when you think of a dog
concepts
A mental representation of a category
Family resemblance
Members of a category share overlapping features
Graded membership
The idea that some category members are more representative of a category than others and are closer in degree to the prototype
