Knowledge Flashcards
Prototype Approach
membership in a category is determined by comparing the object to a typical member or average representation of a member of the category.
Exemplar Approach
membership in a category is determined by many examples of actual members of a category that the person has encountered in the past.
Semantic Network Approach
The idea that concepts are represented by a complex arrangement of interconnected nodes that define the relationship between properties, exemplars, relationships, subsets, and supersets. (Collins and Quillian’s network)
Connectionist Approach
The idea that concepts can be represented by a network of interconnected units that make population codes. Information is transferred by passing through the connections from unit to unit.
Graceful degradation
disruption of performance occurs only gradually as parts of the system are damaged.
Semantic category approach
there are specific neural circuits in the brain for some specific categories.
Connection weight
determines how signals sent from one unit either decrease or increase the activity of the next unit.
Sensory-Functional hypothesis
The ability to differentiate living things and artifacts depends on a semantic memory system that distinguishes sensory attributes and a system that distinguishes function.
Multiple factor approach
Describing how concepts are represented in the brain by searching for multiple factors that determine how concepts are divided up within a category.
Embodied cognition approach
Our knowledge of concepts is based on reactivation of sensory and motor processes that occur when we interact with the object.
