Study Notes

Categorization and Prototypes in Psychology

Categorization is gradual, based on "more-and-less" rather than "all-or-nothing"
The prototype approach determines membership in a category by comparing objects to a prototype, which is an average representation of the most common members of a category
High typicality indicates that a category member closely resembles the category prototype, while low typicality means the member does not closely resemble the prototype
Rosch (1975) extended the prototype approach to quantify typicality for a high number of category members through subjective rating
Rosch and Mervis (1975) found a correlation between family resemblance and typicality, confirming that the higher the family resemblance, the more prototypical an object is
The typicality effect emphasizes that highly prototypical objects are judged more rapidly, indicating that not all members of a category have equal status
Smith (1974) used the sentence verification technique to determine how rapidly people could answer questions about an object's category, finding that prototypical objects are named first when listing objects in a category
Prototypical objects are affected more by priming, as demonstrated by Rosch (1975), indicating that they are more affected by a priming stimulus than non-prototypical members
The exemplar approach to categorization involves determining whether an object is similar to other objects based on actual members of the category that a person has encountered in the past
The exemplar and prototype approaches can explain the typicality effect, with reaction times on the sentence verification task being faster for good examples of a category than poor examples
Exemplars may work best for small categories, while prototypes may work best for larger categories
Hierarchical organization involves dividing large, more general categories into smaller, more specific categories, creating multiple levels of categories, with basic level categories being especially important.
