In order to elucidate the nature of the effect of small cue-response separations on pattern discriminations by monkeys, three studies were performed. When training on a pattern discrimination with a cue-response separation was discontinued during performance at the chance level, there was no saving on the rate of learning a second task (with identical cues but a different cue-response separation) relative to the performance of naive control animals. By contrast, when training was discontinued at a performance level a little better than chance, there was significant saving on learning a second task. After learning the second task, a third task with new pattern cues was learned, with marked saving on the duration of performance at the chance level. The results indicate that during the initial stage of performance at the chance level, monkeys do not attend to cues if there is even a small separation between the cue and the response site.
为了阐明猴子在模式辨别中，小线索-反应间隔效应的本质，进行了三项研究。当在随机水平上进行模式辨别训练时，若线索-反应间隔训练中断，相对于未经训练的对照动物的表现，在学习第二项任务（线索相同但线索-反应间隔不同）的速率上没有节省。相比之下，当训练在略高于随机水平的表现阶段中断时，在学习第二项任务上有显著的节省。在学习第二项任务后，学习了具有新模式线索的第三项任务，在随机水平上的表现持续时间有显著节省。结果表明，在随机水平表现的初始阶段，如果线索与反应部位之间即使有很小的间隔，猴子也不会注意线索。
