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.
本科生接受了一种混合固定比率低比率强化差异时间表。调整时间表组成部分的值，以便一个组成部分中的强化物间隔比另一个组成部分中的强化物间隔更长。在此之后，实施了一个混合固定间隔5秒固定间隔20秒的时间表（实验1）或六个固定间隔时间表，其值范围从5秒到40秒（实验2）。在两个实验中，当强化物间隔接近固定比率时间表下产生的间隔时，固定间隔时间表下的反应率较高，而当强化物间隔接近低比率强化差异时间表下产生的间隔时，反应率较低。目前的结果表明，行为历史的影响受强化物间隔作为辨别性刺激的控制。
