The matching game: Testing for the generality of the matching law

The matching law suggests that animals will allocate responses as a function of reinforcer availability; that is, if one choice produces more reinforcement, a greater proportion of total responding will be allocated to that choice. Indeed, there tends to be a match between response allocation and proportions of reinforcers delivered, given each of those choices. A computer game that delivers simulated coins of experimenter-selected denominations for responding on either of two keys was developed to test the generality of the matching law. The data suggest that even within a single 10-min session, matching functions may be obtained (although undermatching was the rule in the present results). This program may also be used to test various accounts of the matching law.
