Cooper ch 17 generalization/SD Flashcards
a stimulus in the presence of which responses of some type have been reinforced and in the absence of which the same type of responses have occurred and not been reinforced
SD
a stimulus in the presence of which a given behavior has not produced reinforcement in the past
S-Delta
a situation in which the frequency, latency, duration, or amplitude of a behavior is altered by the presence or absence of an antecedent stimulus.
Stimulus control
When an antecedent stimulus has a history of evoking a response that has been reinforced in its presence, the same type of behavior tends to be evoked by stimuli that share similar physical properties with the controlling antecedent stimulus.
Stimulus generalization
occurs when different stimuli do not evoke the response.
Stimulus discrimination
- What does the conventional procedure for stimulus discrimination training require?
Requires one behavior and two antecedent stimulus conditions
a complex example of stimulus control that requires both stimulus generalization within a class of stimuli and discrimination between classes of stimuli.
Concept formation
a set of stimuli that share a common relation. will evoke the same operant response class, or elicit the same respondent behavior.
Antecedent stimulus class
A positive in all 3 behavioral tests (reflexivity, symmetry, and transitivity) is necessary to be defined as this. It’s the emergence of accurate responding to untrained and nonreinforced stimulus-stimulus relations following the reinforcement of responses to some stimulus-stimulus relations.
Stimulus equivalence
3 ways to test for stimulus equivalence.
o Reflexivity: Occurs when in the absence of training and reinforcement a response will select a stimulus that is matched to itself (A=A) Example: matching a picture of a car to a car).
o Symmetry: occurs with the reversibility of the sample stimulus and comparison stimulus (if A=B, then B=A). (If given the verbal direction “car,” learner finds picture of car, then when presented with a picture of “car,” can give verbal identification of “car”
o Transitivity: untrained stimulus-stimulus relation (untrained generalization)
• Reflexivity: Also called generalized identity matching
procedure for investigating conditional relations and stimulus equivalence. Format of trial:
Matching to sample
supplementary antecedent stimuli used to occasion a correct response in the presence of as SD that will eventually control the behavior.
