Lesson 8 - Concepts Flashcards
Inference
refers to the logical interpretations and conclusions that were never part of the original stimulus material.
Semantic memory
refers to our organized knowledge about the world.
Episodic Memory
contains information about events that happen to us
category
is a set of objects that belong together
concept
refers to your mental representations of a category
situated cognition approach
we make use of information in the immediate environment or situation
prototype
is the item that is the best, most typical example of a category
prototype approach
you decide whether a particular item belongs to a category by comparing this item with a prototype. If the item is similar to the prototype, you include that item within this category.
prototypicality
the degree to which they are representative of their category
graded structure
begins with the most representative or prototypical members, and it continues on through the category’s nonprototypical members
typicality effect
occurs when people judge typical items ( prototypes) faster than items that are not typical ( nonprototypes)
semantic priming effect
means that people respond faster to an items if it was preceded by an item with similar meaning
Family resemblance
means that 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.
superordinate-level categories
which means that they are higher-level or more general categories. “ Furniture”, “animal”, “tool” are all examples of superordinate-level categories
Basic -level categories
are moderately specific. “ Chair”, “dog” “screwdriver” are examples of basic level categories
subordinate-level categories
refer to lower level or more specific categories. “ Desk chair”, “collie”, and “ Phillips screwdriver” are all examples of subordinate categories.
examplar approach
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.
examplar
each example stored in memory
Comparing prototype and examplar approaches
The prototype approach proposes that your stored representation is a typical member of the category. In contrast, the examplar approach proposes that your stored representation is a collection of numerous specific members of the category.
