A central issue in studies of vocalizations of non-human primates is the extent of their plasticity. Japanese macaques, Macaca fuscata, frequently utter coo calls and exchange these calls with other group members to maintain contact vocally. I conducted a playback experiment to examine whether monkeys that respond vocally match the acoustic features of their reply to those of the calls they have heard. Six to eight stimulus calls with different acoustic properties in terms of fundamental frequency components were played back to each of seven females, in an attempt to elicit replies from the subjects. There were significant positive regressions of the frequency range of stimuli with that of the replies. Japanese macaques thus matched some of the acoustic features of their replies to those of the preceding calls, suggesting that they might be able to modify the acoustic features of their calls according to the features of the prior calls of another group member.Copyright 1998 The Association for the Study of Animal Behaviour Copyright 1998 The Association for the Study of Animal Behaviour.
对非人类灵长类动物发声的研究中的一个核心问题是其可塑性的程度。日本猕猴（Macaca fuscata）经常发出咕咕叫声，并与其他群体成员交换这些叫声以保持声音上的联系。我进行了一项回放实验，以检验那些通过发声做出反应的猴子，其回复的声学特征是否与它们所听到的叫声的声学特征相匹配。针对七只雌性猕猴中的每一只，播放了六个到八个在基频成分方面具有不同声学特性的刺激叫声，试图引发受试猕猴的回复。刺激叫声的频率范围与回复的频率范围之间存在显著的正相关。因此，日本猕猴使其回复的一些声学特征与之前叫声的声学特征相匹配，这表明它们可能能够根据其他群体成员先前叫声的特征来改变自身叫声的声学特征。版权所有1998动物行为研究协会 版权所有1998动物行为研究协会。
