One group of undergraduates responded under a fixedratio (FR) 25 schedule and a second group responded under a differential-reinforcement-of-low-rate (DRL) 5-s schedule (first history phase). Both groups of subjects were then exposed to a differential-reinforcement-of-other-behavior (DRO) 5-s schedule (second history phase), and finally to fixed-interval (FI) 5-s (Experiment 1), variable-interval (VI) 5-s (Experiment 2), extinction, FR, and DRL (Experiment 3) schedules (history testing phase). Response rates under the extinction and the FR schedule in the history-testing phase were higher for subjects with a history of the FR schedule than for subjects with a DRL history. Such a systematic difference by remote histories was not observed when the FI, VI, and DRL schedules were in effect during testing.
