Classical Conditioning: Compound CSs and the Rescorla-Wagner Model
Chapter Three concluded with a statement of the need for a model of classical conditioning that predicts the effects of reinforcement and nonreinforcement on a trial-by-trial basis, accounts for the outcomes of various manipulations of the contingency between CS and UCS, and predicts the net associative effects of several different conditioning treatments given in succession. Such a model was devised by Rescorla and Wagner (1972; Wagner & Rescorla, 1972) to meet these needs, but also to explain provocative new variations in the effects of reinforcement and non-reinforcement in cases where more than one CS was presented on a trial.
