Pigeons were trained to respond in a two-link, concurrent-chain schedule. Pecks on each key during the concurrent initial links occasionally produced a 5-min terminal link, during which only that key was operative. Food reinforcement and various intensities of shock were scheduled during the terminal links. When shock was contingent on response, the effect of shock was greater on terminal-link responding than on initial-link responding. When shock was independent of response, the effect was reversed, with larger changes in initial-link responding than terminal-link responding. In general, shock was found to affect behavior most drastically when behavior could, in turn, affect the rate of shock.
鸽子被训练在一个双链接、并发链的时间表中做出反应。在并发的初始链接中，偶尔啄一下每个键会产生一个 5 分钟的终端链接，在此期间只有那个键是有效的。在终端链接期间，安排了食物强化和不同强度的电击。当电击与反应相关联时，电击对终端链接反应的影响比对初始链接反应的影响更大。当电击与反应无关时，效果相反，初始链接反应的变化比终端链接反应的变化更大。总的来说，当行为反过来可以影响电击的速度时，发现电击对行为的影响最剧烈。
