Stimulus Control Flashcards
Concept formation
Complex example of stimulus control that requires both stimulus generalisation within a class of stimuli and discrimination between classes of stimuli.
Antecedent stimulus class
A set of stimuli that share a common relationship - will evoke or elicit same response
Feature stimulus class
Stimuli that share common physical forms or common relative relations
Arbitrary stimulus class
Evoke the same response but they do not share a common stimulus feature.
Prompts
Supplementary antecedent stimuli used to occasion a correct response in the presence of an SD that will eventually control the behaviour
Response prompts
Operate directly to the response
Stimulus prompts
Operate directly on the antecedent task stimuli to cue a correct response in conjunction with the critical Sd.
Procedures for transferring stimulus control from response prompts to naturally existing stimuli
- Most-to-least
- Graduated guidance
- Least-to-most
- Time delay
Stimulus fading
Hi lighting a physical dimension (e.g. colour, shape, position) of a stimulus to increase the likelihood of a correct response
Stimulus shape transformation
An initial stimulus shape that will prompt the correct response is gradually changer to form the natural stimulus while maintaining correct responding.
Stimulus control
Occurs when the rate, latency, duration or amplitude of a response is altered in the presence of an antecedent stimulus
Discriminative stimuli and motivating operation similarities
- Both events occur BEFORE the behaviour of interest
2. Both events have EVOCATIVE functions
Stimulus generalisation
The general tendency of stimuli that share similar physical properties with the controlling A stimilus to evoke the same B
Stimulus generalisation gradient
Graphically depicts the degree of stimulus generalisation and discrimination by showing the extent to which responses reinforced in one stimulus condition are emitted in presence of untrained stimuli
Stimulus equivalence
the emergence of accurate responding to untrained and non-reinforced stimulus-stimulus relations following the reinforcement of responses to some other stimulus-stimulus relations.
