Chapter 16: Transferring behavior to new settings and making it last: generality of behavioral change Generality: trained behavior transfers from the training situation to the natural environment, when training leads to the development of new behavior that has not been specifically trained, or when the trained behavior is maintained in the natural environment over time Stimulus generalization of operant conditioning Occurs when behavior becomes more probable in the presence of one stimulus or situation as a result of having been reinforced in the presence of another stimulus or situation The more physically similar two stimuli are, the more stimulus generalization will occur b/w themthis is inherited/ unlearned Concepts o SG might occur from one stimulus to another because we have learned that the two stimuli are members of a stimulus common-element classa set of stimuli that have some physical characteristic in common o SG might occur from one stimulus to another because we have learned that the stimuli are members of an equivalence classa set of completely dissimilar stimuli that an individual has been trained to match together stimuli are functionally equivalent in the sense that they control the same response Stimulus generalization of respondent conditioning Respondent CR occurs to a new stimulus Response generalization Occurs when a behavior becomes more probable in the presence of a stimulus or situation as a result of another behavior having been strengthened in the presence of that stimulus or situation Unlearned response generalization due to considerable physical similarity of responses o Example: can rollerblade easily if you first learned to ice skate because the responses involved in the two activities are similar Learned response generalization based on minimal physical similarity of responses o Example: when Stan says I have to ask my mother instead of teachertwo sentences are different but have common grammatical structure and share some of the same words Learned response generalization due to functionally equivalent responses o Different responses that produce the same consequences are called functionally equivalent responses o Example: asked to light a fire; might light a match, rub two sticks together, flip a lighter o Important application of functionally equivalent responses in applied settings is termed behavioral momentum o As a result of some responses being emitted and reinforced, the probability of other functionally equivalent responses momentarily increases Factors influencing the effectiveness of programming generality of operant behavior Training situation must be distinguished from target situation in which we want generality to occur (target behavior is usually but not necessarily the natural environment) Programming for generality is somewhat different for operant and respondent behavior Programming for generality of operant behavior change includes strategies of programming for stimulus generalization, response generalization and behavior maintenance Programming operant stimulus generalization Initial occurrence of SG depends on physical similarity between the training and target situations Train in the target situation o Make the final stages of training situation similar to the target situation in as many ways as possible Vary the training conditions o Conduct training sessions with relatively little control over the stimuli in the presence of which correct responses are reinforced o If behaviors are brought under the control of a greater variety of stimuli during training, then there is an increased probability of some of those stimuli being present in the target situation
