Four rhesus monkeys were trained to respond on one key when a one-second noise burst was presented through one speaker and to respond on a second key when the noise burst was presented through a second speaker. The acquisition of stimulus control was studied under three conditions, in each of which the relationship between the sound source and the response-key positions varied: an adjacent condition in which the noise burst was presented through the key and a response on this key was reinforced; a reversed-adjacent condition in which the noise burst was presented through one key and responding on the other key was reinforced: and a nonadiacent condition in which responding on the key nearer the sound was reinforced. Under adjacent conditions, stimulus control developed within one or two sessions. Under reversed and nonadjacent conditions, 10 sessions were required for the development of control. The asymptote of correct responding was the same under each condition in all animals.
训练了四只恒河猴，当通过一个扬声器发出一秒钟的噪声脉冲时，它们要在一个按键上做出反应；当噪声脉冲通过第二个扬声器发出时，它们要在第二个按键上做出反应。在三种条件下研究了刺激控制的习得情况，在每种条件下，声源与反应按键位置之间的关系各不相同：一种是相邻条件，即通过按键发出噪声脉冲，并对该按键上的反应进行强化；一种是反向相邻条件，即通过一个按键发出噪声脉冲，并对另一个按键上的反应进行强化；还有一种是非相邻条件，即对离声音较近的按键上的反应进行强化。在相邻条件下，刺激控制在一两个实验环节内就得以发展。在反向和非相邻条件下，需要10个实验环节才能发展出控制。在所有动物的每种条件下，正确反应的渐近线都是相同的。
