鸽子的啄键活动按照三部分多重时间表进行。在一个组件中，串联可变间隔固定比率 10 的计划保持了高响应率。在第二个部分中，串联可变间隔差异强化低速率 5 秒计划保持了较低的响应率。这些组件以 15、30 或 45 秒的间隔交替，并且室内有 15 秒的黑暗期（停电）。在停电期间根据可变时间 15、30 或 150 秒的时间表添加与反应无关的食物呈现，对这两个组成部分的变化产生了不同的抵抗力。随着与反应无关的食物呈现更加频繁，高速率成分中的反应比低速率成分中的反应减少更多，即对变化的抵抗力更小。从逻辑上讲，这些影响更多地归因于停电期间独立于响应的食品供应与响应中普遍发生的意外事件之间的相互作用，而不是响应率本身。还讨论了这些数据与反应无关强化研究的关系。
Pigeons'' key-pecking was maintained on three-component multiple schedules. In one component a tandem variable-interval fixed-ratio 10 schedule maintained high response rates. In the second component a tandem variable-interval differential-reinforcement-of-low-rate 5-s schedule maintained lower response rates. These components alternated at 15-, 30-, or 45-s intervals with a 15-s period of darkness (blackout) in the chamber. Response-independent food presentations, added during the blackout according to variable-time 15-, 30-, or 150-s schedules, yielded differential resistance to change in the two components. With more frequent response-independent food presentations, responding in the high-rate component was reduced more, that is, was less resistant to change, than that in the low rate component. The effects are more logically attributed to the interaction between the response-independent food delivery in the blackout and prevailing contingencies on responding than to response rates per se. The relation of these data to the study of response-independent reinforcement also is discussed.
