鸽子的表现已经按照时间表进行了研究，在该时间表上，只有在有反应之后经过一段指定的“延迟”期而没有反应时，才会出现强化刺激。即使这个时间长达 100 秒，反应速度仍高于以 100 秒间隔呈现强化刺激而产生的速度，而与反应无关。响应和强化刺激之间的等待时间分别为 30 秒和 10 秒，等待时间越短，总体响应率越高。发现戊巴比妥和甲基苯丙胺的作用因等待期的变化而有不同的改变。除了“延迟”期间的反应不会推迟强化之外，在所有方面都相似的时间表上，反应率往往更高。
The performance of pigeons has been studied on schedules on which reinforcing stimuli were presented only when a response was followed by some specified "delay" period without a response. Even when this period was as long as 100 seconds, responding was maintained at rates above those resulting from presentation of the reinforcing stimuli at 100-second intervals noncontingent on responding. With waiting periods of 30 seconds and of 10 seconds between response and reinforcing stimuli, the over-all rate of responding was higher with the shorter waiting periods. The effects of pentobarbital and of methamphetamine were found differentially modified by change in the waiting period. The rate of responding tended to be higher on schedules similar in all respects except that responses during the "delay" period did not postpone reinforcement.
