When the rate, latency, amplitude or duration of a response is altered in the presence of an antecedent stimulus.
A group of stimuli that share specific common elements along formal, temporal and/or functional dimensions.
Conditioned stimulus (CS)
A formerly neutral stimulus that elicits respondent behavior only after it has been paired with an unconditioned stimulus or another conditioned reflex.
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 not been reinforced.
A stimulus change that increases the frequency of any behavior that immediately precedes it.
Stimulus discrimination training
Responses are reinforced in the presence of the Sd but not in the presence of the S delta. The person will learn not to respond in the presence of the S delta.
An antecedent stimulus consistently evokes a response because it has been reinforced; stimulus generalization occurs when UNTAUGHT stimuli that are similar to that taught stimuli, also evoke that response.
Feature stimulus class
Stimuli that share common physical forms or structures or relative relationships. "made from wood".
Dependent and/or temporal relations between operant behavior and its controlling variables.
A contingency in which a response presents or postpones the presentation of a stimulus.
Stimulus change that increases the frequency of behavior that precedes irrespective of the organisms learning history.
Unconditioned negative reinforcer
Stimulus change that functions as a negative reinforcer as a result of phylogeny, no prior learning.
A stimulus change that decresaes the future frequency of behavior that precedes it that is not paired with any other punishers, ex. pain, bad taste.
A behavior is followed immediately by the presentation of a stimulus that decreases the future frequency of behavior.
