Abstract

Monkeys (Macaca) were trained by operant conditioning techniques to report the minimum detectable change in location of a sound in space, and were tested with a series of recorded coo or clear call vocalizations. Acuity of localization varied from approximately 4 degrees to 15 degrees and was a function of the magnitude of the change in pitch (frequency modulation) of the different clear calls.

摘要

通过操作性条件反射技术训练猴子（猕猴属）报告空间中声音位置的最小可察觉变化，并使用一系列录制的咕咕声或清晰叫声进行测试。定位敏锐度在约4度至15度之间变化，并且是不同清晰叫声音高变化（频率调制）幅度的函数。
