The Prototype Approach

Empirical Evidence

Data obtained through observation and experimentation to support a theory or hypothesis.

Eleanor Rosch (1975)

Psychologist who conducted studies on category membership and typicality.

Prototype

An ideal or most representative example of a category.

Typicality Effect

The phenomenon where some category members are judged to be better examples than others.

High Prototypicality

A category member that closely resembles the category prototype.

Low Prototypicality

A category member that does not closely resemble the category prototype.

Sentence Verification Technique

A method used to measure response times to verify category membership.

Central Member

A category member that is considered a typical example (e.g., apple in the fruit category).

Peripheral Member

A category member that is less typical (e.g., fig in the fruit category).

Cognitive Reference Points

Highly typical instances used as benchmarks for comparison in categorization.

Prototype Approach

A method of categorization based on the most typical member of a category.

Limitations of Prototype Approach

Prototypes may not represent the features of most members and can be influenced by familiarity.

Exemplar Approach

A method of categorization that uses multiple specific examples rather than a single prototype.

Family Resemblance Effect

The idea that the more similar an item is to known examples, the faster it can be categorized.

Benefits of Exemplar Approach

Explains difficulties in categorization and typicality effects by relying on stored instances.

Problems with Exemplar Approach

Lacks clarity on which instances are stored and how they are organized for categorization.

Abstraction Continuum

The concept that prototypes and exemplars may represent two ends of a spectrum in categorization methods.
