Three rats, lever pressing for food delivered on a fixed-interval 128-s schedule, were presented with a 16-s opportunity to drink from a retractable water source. The temporal placement of the water probe within the reinforcement cycle was varied sequentially, in steps of 16 s. Although the lever-pressing pattern was modulated by the intercalated water probe, water consumption during the probe itself was a decreasing function of time from the following reinforcer. These results were interpreted as evidence against the notion that schedule-induced drinking is a "ubiquitous" phenomenon and are congruent with results from other "intruded stimulus" experiments.
三只大鼠在固定间隔128秒的食物递送时间表下按压杠杆获取食物，它们有16秒的机会从可伸缩水源饮水。水探测在强化周期内的时间安排以16秒为步长依次变化。尽管杠杆按压模式受到插入的水探测的调节，但探测期间的饮水量是距离下一次强化物时间的递减函数。这些结果被解释为反对定时诱导饮水是一种“普遍存在”现象这一观点的证据，并且与其他“侵入性刺激”实验的结果一致。
