Stimuli Flashcards
A stimulus class whose members share a common set of features
Concept
Performance in a match-to-sample procedure in which discrimination between the comparison stimuli is conditional on, or depends on, the sample stimulus present on each trial
Conditional Discrimination
A procedure for transferring stimulus control from contrived response prompts to naturally existing stimuli by increasing the duration of a delay from the initial SD to the response prompt
Constant Time Delay
A stimulus in the presence of which a given behavior has been reinforced and in the absence of which that behavior has not been reinforced. It’s presence signals the availability of reinforcement
Discriminative Stimulus (SD)
A variety of techniques for gradually transferring stimulus control with a minimum of errors
Errorless Learning
Stimuli that share common physical forms or structures or common relative relationships
Feature stimulus class
A technique of transferring stimulus control where response prompts are provided beginning with least intrusive and increasing to the most intrusive. If the participant does not respond independently the prompt level is increased
Least-to-most response prompts
A discrete trial procedure for investigating conditional relations and stimulus equivalence. The participants makes a selection from a field that matches a sample stimulus.
Matching-to-sample
A technique of transferring stimulus control in which the practitioner physically guides the participant through the response and then gradually reduces prompts over successive trials.
Most-to-least response prompts
A condition in which the range of discriminative stimuli, or stimulus features controlling behavior, is extremely limited and interferes with learning
Over selective stimulus control
Occurs when the most salient component of a compound stimulus arrangement controls responding and interferes with the acquisition of stimulus control by the more relevant stimulus
Overshadowing
A procedure for transferring stimulus control that starts with simultaneous presentation of the stimulus and the prompt. The time delay is gradually and systematically extended.
Progressive time delay
Prompts that operate directly on the response to cue a correct response. The three major forms are verbal instructions, modeling, and physical guidance.
Response prompts
Occurs when a competing stimulus blocks the evocative function of a stimulus that has acquired stimulus control over the behavior. Sometimes called masking
Stimulus blocking
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
A stimulus in the presence of which a given behavior has not produced reinforcement, or has produced reinforcement of lesser quality, in the past
Stimulus Delta (S^)
When one stimulus(SD) signals the availability of reinforcement and the absence of that stimulus (S^) signals a zero or reduced chance of reinforcement. Responses occur more often in the presence of the SD.
Stimulus Discrimination
The conventional procedure requires one behavior and two antecedent stimulus conditions. Responses are reinforced in the presence of one stimulus condition, the SD, but not in the presence of the other stimulus, S^.
Stimulus Discrimination training
A method of transferring stimulus control that involves highlighting a physical dimension of a stimulus to increase the likelihood of a correct response and then diminishing that exaggeration over time
Stimulus fading
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 evokes by stimuli that share similar physical properties with the controlling stimulus
Stimulus Generalization
A graphic depiction of the extent to which behavior that has been reinforced in the presence of a specific stimulus condition is emitted in the presence of other stimuli
Stimulus generalization gradient
Prompts that operate directly on the antecedent task stimuli to cue a correct responses in conjunction with the critical SD.
Stimulus Prompts
A procedure for transferring stimulus control from contrived responses prompts to naturally existing stimuli in which the delay between the stimuli and the prompt are increased based on the participant responding.
