Undergraduates were exposed to a mixed fixed‐ratio differential‐reinforcement‐of‐low‐rate schedule. Values of the schedule components were adjusted so that interreinforcer intervals in one component were longer than those in another component. Following this, a mixed fixed‐interval 5‐s fixed‐interval 20‐s schedule (Experiment 1) or six fixed‐interval schedules in which the values ranged from 5 to 40 s (Experiment 2) were in effect. In both experiments, response rates under the fixed‐interval schedules were higher when the interreinforcer intervals approximated those produced under the fixed‐ratio schedule, whereas the rates were lower when the interreinforcer intervals approximated those produced under the different‐reinforcement‐of‐low‐rate schedule. The present results demonstrate that the effects of behavioral history were under control of the interreinforcer intervals as discriminative stimuli.
