Changes in auditory sensitivity as a function of signal duration were studied in two species of Old World monkeys. Testing was conducted under free-field conditions with pure tones 250, 800, 1600, and 4000 Hz in frequency. Test stimuli ranged in duration from 35-2000 ms. The results showed that the temporal integration functions for the blue monkeys were similar to those reported for rhesus monkeys [T. D. Clack, J. Acoust. Soc. Am. 40, 1140-1146 (1966)], but differed significantly from those for mangabey monkeys and human subjects tested in the same apparatus, by the same procedure. Integration functions for humans and mangabeys did not differ. It was concluded that some taxonomic groups of primates exhibit temporal integration times that are much longer than those characteristic of humans, while others do not, and that interspecific differences in temporal integration are not readily related to species differences in their vocal repertoires.
在两种旧大陆猴中研究了听觉敏感度随信号持续时间的变化。测试是在自由场条件下,使用频率为250、800、1600和4000赫兹的纯音进行的。测试刺激的持续时间从35毫秒到2000毫秒不等。结果表明,蓝猴的时间整合功能与恒河猴的相似 [T. D. 克拉克,《美国声学学会杂志》40, 1140 - 1146 (1966)],但与在同一设备中、通过相同程序测试的白眉猴和人类受试者的时间整合功能有显著差异。人类和白眉猴的整合功能没有差异。得出的结论是,一些灵长类分类群体表现出比人类特征长得多的时间整合时间,而其他群体则不然,并且时间整合的种间差异与它们的发声库中的物种差异没有直接关系。
