Chapter 17 Flashcards
Discriminative Stimulus
Signals that reinforcement is available.
Stimulus Delta
Signals that reinforcement is not available.
Stimulus Control
Behavior that occurs more often in the presence of a stimulus than without it.
Stimulus Discrimination
When an organism responds to an SD and does not respond to a stimulus delta.
Stimulus Generalization
Refers to the extent to which stimuli other than the SD acquire stimulus control over the behavior. Stimuli sharing similar physical properties with the SD are most likely to acquire evocative function.
Stimulus Generalization Gradient
Graphically depicts the degree of stimulus generalization and discrimination by showing the extent to which responses reinforced in one stimulus condition are emitted in the presence of untrained stimuli.
Faulty Stimulus Control
Occurs when a behavior comes under the restricted control of an irrelevant antecedent stimulus.
Conditioned Discrimination
The response that will produce reinforcement in the presence of a particular stimulus depends on (is conditional on) the presence or absence of other stimuli.
Stimulus Discrimination Training
Entails a multiple schedule with antecedent stimulus conditions representing each component schedule. Responses in the presence of one stimulus condition is reinforced, responses in the presence of the other stimulus are not reinforced.
Concept
Is defined by a set of shared features found in each example of the concept
Antecedent Stimulus Class
Set of stimuli that share a common relationship.
Feature Stimulus Class
Share common physical forms or common relative relations. Feature stimulus classes include an infinite number of stimuli and constitute a larger portion of our conceptual behavior.
Arbitrary Stimulus Class
Evoke the same response, but they do not share a common stimulus feature.
Response Prompts
Operate Directly on the response to cue to correct response
Stimulus Prompts
Operate directly on antecedent task stimuli to cue a correct response in conjunction with the critical SD
Overselective Stimulus Control
The range of discriminative stimuli or stimulus features controlling behavior is extremely limited
Stimulus Blocking
Even though one stimulus has acquired stimulus control over behavior, a competiting stimulus can block the evocative function of that stimulus.
Overshadowing
The most salient component of a compound stimulus arrangement controls responding and interferes with the acquisition of stimulus control by the more relvant stimulus.
Time Delay
Procedure begins with simultaneous presentation of the target stimulus and response prompt. After the student has responded correctly for several trials, the teacher inserts a delay between the instructional stimulus and the response prompt until the student emits the unprompted correct response.
Progressive Time Delay
Starts with simultaneous presentation of natural stimulus and the response prompts, several sec trials before increasing the time delay.
Stimulus Fading
Involves highlighting a physical dimension of a stimulus to increase the likelihood of a correct response.
