Monkeys require a considerably larger number of trials to bring responding under the control of the location of an auditory stimulus than cats, rats, and bats with the same experimental procedures. The present experiment sought to determine the conditions necessary for rapid acquisition of control of responding by location of noise and tone bursts in the monkey. Monkeys were run in an enclosure that contained four loudspeakers and four manipulanda. Two conditions were used in training. In the adjacent condition, a stimulus (noise or tone burst) was presented through one or other of two speakers and a response on the manipulandum adjacent to the speaker was reinforced with food. In the nonadjacent condition, a stimulus was presented through one of two speakers and a response on a manipulandum remote from the speaker was reinforced with food. Acquisition of control was measured by change in the percentage of reinforced responses during training. In the adjacent condition, responding came under control of location within zero to three sessions. In nonadjacent conditions, the animals required 14 to 20 sessions to come under control of location. These latter numbers are comparable to those reported in the literature for localization discrimination in monkeys.
在相同的实验程序下，猴子要比猫、大鼠和蝙蝠需要更多的试验次数才能使反应受听觉刺激位置的控制。本实验旨在确定猴子快速习得受噪声和短音突发位置控制的反应所需的条件。猴子在一个装有四个扬声器和四个操作装置的围栏中进行实验。训练采用了两种条件。在相邻条件下，通过两个扬声器中的一个或另一个呈现刺激（噪声或短音突发），并对与扬声器相邻的操作装置上的反应给予食物强化。在非相邻条件下，通过两个扬声器中的一个呈现刺激，并对远离扬声器的操作装置上的反应给予食物强化。通过训练期间强化反应百分比的变化来衡量对位置控制的习得情况。在相邻条件下，反应在零至三个训练单元内就受位置控制。在非相邻条件下，动物需要14至20个训练单元才能受位置控制。后一组数字与文献中报道的猴子定位辨别情况相当。
