The process of recurrent choice.

Recurrent choice has been studied for many years. A static law, matching, has been established, but there is no consensus on the underlying dynamic process. The authors distinguish between dynamic models in which the model state is identified with directly measurable behavioral properties (performance models) and models in which the relation between behavior and state is indirect (state models). Most popular dynamic choice models are local, performance models. The authors show that behavior in different types of discrimination-reversal experiments and in extinction is not explained by 2 versions of a popular local model and that the nonlocal cumulative-effects model is consistent with matching and that it can duplicate the major properties of recurrent choice in a set of discrimination-reversal experiments. The model can also duplicate results from several other experiments on extinction after complex discrimination training.
