chapter 8 Flashcards
- Sets of objects that belong together
- Considered to be “partly” equal
Category
Different objects can be grouped together because of their _____
functions
- Mental representations of a category
- Allow individuals to organize their knowledge, make inferences, and categorize objects based on their functions and characteristics
Concept
- Formed through experiences
- Plays a crucial role in semantic memory
Concept
We make sense of our cognition based on the situation we are in
Situated Cognition Approach
- Long-term memory that is responsible for storing general knowledge
- Allow us to organize objects we encounter
Semantic Memory
Eleanor Rosch’s theory: we organize each category on the basis of a prototype
The Prototype Approach
the item that is the best, most typical example of a category
Prototype
you decide whether a particular item belongs to a category by comparing this item with a prototype
Prototype Approach
degree to which they are representative of their category
Prototypicality
begins with the most representative or prototypical members, and it continues on through the category’s non-prototypical members
Graded structure
Characteristics of Prototypes
- Prototypes are supplied as examples of a category
- Prototypes are judged more quickly than non-prototypes, after semantic priming
- Prototypes share attributes in a family resemblance category
occurs when people judge typical items (prototypes) faster than items that are not typical (non-prototypes)
Typicality Effect
people respond faster to an item if it was preceded by an item with similar meaning
Semantic Priming Effect
_____ facilitates people’s responses to prototypes significantly more than it facilitated responses to non-prototypes
semantic priming
no single attribute is shared by all examples of a concept; however, each example has at least one attribute in common with some other example of the concept
Family resemblance
Levels of Categorization
- Superordinate-level categories
- Basic-level categories
- Subordinate-level categories
Levels of Categorization: means that they are higher-level or more general categories
Superordinate-level categories
Levels of Categorization: moderately specific
Basic-level categories
Levels of Categorization: refer to lower-level or more specific categories
Subordinate-level categories
the best example of a category; a category that is neither too general nor too specific
prototype; basic-level category
T or F: People produce the superordinate or the subordinate names basic-level names faster than basic-level names
false; People produce the BASIC-LEVEL NAMES names faster than either the superordinate or the subordinate names
a superordinate term (e.g., toy) is more likely than a basic-level term (e.g., doll) to activate part of the _____
prefrontal cortex
this part of the cortex processes language and associative memory
prefrontal cortex
subordinate terms (e.g., rag doll) are more likely than basic-level terms (e.g., doll) to activate part of the _____ of the brain
parietal region
The _____ is active when you perform a visual search
parietal lobe
argues that we first learn information about some specific examples of a concept; we then classify each new stimulus by deciding how closely it resembles all of those specific examples
Exemplar Approach
each examples stored in memory
Exemplar
Exemplar or Prototype Approach: your concept of “dog” would include information about numerous examples of dogs you have known
Exemplar approach
Exemplar or Prototype Approach: your prototype of a dog would be an idealized representation of a dog, with average size for a dog and average other features—but not necessarily like any particular dog you’ve ever seen
Prototype approach
Exemplar or Prototype Approach: Categories are represented by a typical or ideal member
Prototype Approach
Exemplar or Prototype Approach: This approach is efficient for categories with numerous members, as it provides a simplified representation
Prototype Approach
Exemplar or Prototype Approach: categories are represented by a collection of specific instances
Exemplar Approach
Exemplar or Prototype Approach: This approach is suitable for categories with relatively few members and emphasizes retaining specific information about individual instances
Exemplar Approach
abstract representations derived from averaging the features of various category members
Prototypes
individual instances stored in memory, representing actual category members encountered in the past
