Preference for high frequency sounds in human infants are found by other researchers. The purpose of this study is to examine whether nonhuman primates also have the same tendency as human infants. It is important to consider language origins. Two types of tape recorded coo calls, contact calls, with high and low fundamental frequencies were played back as stimuli for two groups of Japanese macaques (Macaca fuscata). The result showed that the animals of both groups preferred high frequency sounds. To ascertain whether other species also have the same tendency as the Japanese macaques, a playback experiment similar to that for Japanese macaques was conducted for one group of ringtailed lemurs (Lemur catta). Tape recorded mew calls, contact calls, were used as stimuli. The results showed that ringtailed lemurs also preferred high frequency sounds. Moreover, it was clarified by an additional playback experiment for one group of Japanese macaques that animals had an affective preference for high frequency sounds. These results suggest that nonhuman primates have a consistent tendency to prefer high frequency sounds.
其他研究人员发现人类婴儿对高频声音有偏好。本研究的目的是检验非人类灵长类动物是否也具有与人类婴儿相同的倾向。考虑语言起源很重要。将两种具有高、低基频的录音咕咕叫声（联络叫声）作为刺激物播放给两组日本猕猴（食蟹猕猴）。结果表明，两组动物都更喜欢高频声音。为了确定其他物种是否也具有与日本猕猴相同的倾向，对一组环尾狐猴（狐猴）进行了与日本猕猴类似的回放实验。使用录音的喵喵叫声（联络叫声）作为刺激物。结果表明，环尾狐猴也更喜欢高频声音。此外，通过对一组日本猕猴进行的额外回放实验表明，动物对高频声音有情感偏好。这些结果表明，非人类灵长类动物有一致的倾向更喜欢高频声音。
