Abstract:
When a functional communication response (FCR) can be reliably occasioned, destructive behavior tends to be lower. However, the form of FCR may affect the durability of functional communication training, as missing FCR materials may promote resurgence. Experiment 1 demonstrated that resurgence of target responding was lower when a vocal FCR remained available but was placed on extinction compared to when a card-based FCR was unavailable. Experiment 2 replicated the finding that initiating treatment with a card FCR produced less target responding than when initiating treatment with a vocal FCR. We then evaluated a set of procedures for transitioning the card FCR to the previously unlearned vocal FCR. These findings suggest benefits of training different types of FCRs at different stages of treatment and provide a preliminary set of procedures for transitioning between FCR topographies while occasioning minimal target responding.

Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
