Rapid control of responding by sound location is obtained in squirrel monkeys when sound stimuli are presented from one of two loudspeakers, each one adjacent to a response key. With this arrangement of loudspeakers and response keys, squirrel monkeys quickly learn to respond on the key near the source of the sound stimulus, and this pattern is the same whether or not responses near the sound source are differentially reinforcedmthis result may depend on a pre-experimental tendency in squirrel monkeys to orient head and eyes toward a sound, which would lead the animal to look at the response key in front of the loudspeaker producing the sound. The present experiment sought to determine whether visual stimuli are necessary for rapid control of responding by sound location. Two monkeys were trained in darkness in a sound-localization task similar to that described above. Results were similar to those obtained from animals trained in light, indicating that visual stimuli are not required for rapid acquisition of sound-localization behavior in monkeys.
当声音刺激从两个扬声器之一发出时，松鼠猴能迅速通过声音定位来控制反应，每个扬声器都与一个反应键相邻。通过这种扬声器和反应键的设置，松鼠猴很快学会在靠近声音刺激源的按键上做出反应，无论靠近声源的反应是否得到差别强化，这种模式都是相同的——这一结果可能取决于松鼠猴在实验前就有的将头部和眼睛朝向声音的倾向，这会使动物看向发出声音的扬声器前面的反应键。本实验旨在确定视觉刺激对于通过声音定位快速控制反应是否必要。两只猴子在黑暗中接受了类似于上述的声音定位任务训练。结果与在有光环境下训练的动物所得结果相似，表明猴子快速习得声音定位行为并不需要视觉刺激。
