| Abstract: | A total of 46 rats, distributed across two experiments, received differential instrumental conditioning trials in a nonchoice brightness-discrimination apparatus. In each experiment, groups differed with respect to the pattern of rewarded and nonrewarded S+ trials. Response in S? was never reinforced. The results of both experiments indicated that the pattern of S+ reward events influences S? response levels in a fashion consistent with expectations derived from stimulus-specificity theory. |
