各组大鼠在自动成形条件下接受了500次杠杆按压训练试验（在10秒杠杆呈现后输送食物，或在反应后立即发生）;操作性条件反射（反应对于食物输送是必要的）;和经典条件反射（无论反应如何，食物都会跟随杠杆呈现）。然后，每组接受500次关于遗漏程序的试验，其中食物在有反应的试验中被省略。另一组接受了1000次关于省略程序的试验，第五组是随机对照组，接受了1000次不相关的杠杆和食物介绍。自动成形，操作和经典组达到高反应水平的初始培训结束。自动整形组的收购速度最快。在对照组中，反应始终较低。遗漏组的反应水平介于控制组和其他三组之间。在省略训练期间，这三个组的反应下降到省略组的水平。在省略训练中，大鼠在压杆下降后继续频繁接触杠杆。遗漏训练下的反应维持似乎不需要反应和完成者引发的完成行为之间的地形相似性。
Separate groups of rats received 500 trials of lever-press training under autoshaping (food delivery followed 10-second lever presentations, or occurred immediately following a response); operant conditioning (responding was necessary for food delivery); and classical conditioning (food followed lever presentations regardless of responding). Each group then received 500 trials on an omission procedure in which food was omitted on trials with a response. Another group received 1000 trials on the omission procedure, and a fifth group, random control, received 1000 uncorrelated presentations of lever and food. The autoshaping, operant, and classical groups reached high response levels by the end of initial training. Acquisition was fastest in the autoshaping group. Responding remained consistently low in the control group. The omission group responded at a level between the control group and the other three groups. During omission training, responding in these three groups declined to the omission-group level. During omission training, the rats continued contacting the lever frequently after lever pressing had declined. Response maintenance under omission training seems not to require topographic similarity between the response and reinforcer-elicited consummatory behaviors.
