Questions and Answers

What is conceptual knowledge?

  • Knowledge that is purely theoretical and not based on real-world observations
  • Knowledge that is limited to abstract ideas and not applicable to practical situations
  • Knowledge that is solely based on sensory experiences
  • Knowledge that enables us to recognize objects and events and make inferences about their properties (correct)

    • What is categorization?

  • The act of identifying the unique features of individual items
  • The process of creating mental representations of concepts
  • The process by which things are placed in groups (correct)
  • The process of assigning labels to objects and events

    • What does a category provide?

  • Abstract representations of conceptual knowledge
  • Detailed sensory descriptions of individual items
  • Specific definitions of each category member
  • Information about expected behavior and how to respond to it (correct)

    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.
