Units in a connectionist network that located between input units and output units
Hidden Units
Organization of categories in which larger, more general categoris are divided into smaller, more specific categoris. These smaller categories can, in turn, be divided into even more specific categories to create a number of levels
Hierarchical organization
a category member that closely resembles the category prototype
High-prototypicality
Units in a connectionist network that are activated by stimulation from the environment
Input units
a procedure in which a person is asked to decide as quickly as possible, whether a particular stimulus is a word of a nonword
Lexical-decision task
a category member that does not resemble the category prototype
Low-prototypicality
units in a connectionist network that contain the final output of the network
Output units
Connectionism
Parallel distributed processing approach (PDP)
a standard used in categorization that is formed by averaging the category members a person has cencountered in the past
Prototype
the idea that we decide whether something si a member of a category by determining whether it is similar to a standard representation of the category called a prototype
Prototype approach to categorization
the degree to which a particular member of a category matches the prototype for that category
Prototypicality
the approach to concepts in which concepts are arrange in networks that represent the way the concepts are orgenized in the mind
Semantic network approach
the participant is asked to indicate whether or not a particular sentence is true or false
Sentence-verification technique
activity that spreads out along any link in a network that is connected to an activated node
Spreading activation
the level in Rosch's categorization scheme that is a level below the basic level
Subordinate level
the highest level in rosch's categorization scheme that corresponds to general categories
Superordinate level
The ability to judge the truth or fasity of sentences involving high-prototypical members of a category more rapidly that sentences involving low-prototypal members of a category
Typicality effect
"neuron-like processing units" in a connectionist network
Units
a condition associated with brain damage in which a person can see an object but cannot name the object
Visual agnosia
the strength of a connection between units in a connectionist network
Weight
