Backward chaining and forward chaining procedures compared in animal models

Chains of stimuli and responses are components of daily interactions with the environment and with other people. Two training procedures, backward and forward chaining, are common in the literature. The presentation will compare the two methods of training and what types of control of behavior result from the training. Animal models will illustrate that even though the two methods result in the same overall behavior chain, the two methods nevertheless generate different training progressions and different types of control of behavior, as revealed when certain tests are made. Apparently, training with forward chaining generates a more “flexible” chain because the subject adjusts more easily to changes made in the chain after it is formed compared with adjustments made to the same changes after training with backward chaining. The presentation will outline implications for use of chaining procedures in applied settings.
