Responses of six squirrel monkey (Saimiri sciureus) mothers to playback of a single call type, the "isolation peep," made by their own infants were tested after mothers and infants had been separated for more than a week. The playback tapes were edited from tapes containing mixed vocal material recorded when infants and mothers could see but not touch each other. Mothers showed recognition of their own infants compared to other familiar infants by increases in four measures of proximity to the speaker. These data provide evidence that maternal recognition of infants by means of acoustic cues is possible when the test stimuli consist of examples of a single call type with demonstrated individuality.
当松鼠猴（Saimiri sciureus）母亲与其幼崽分离一周以上后，我们播放了幼崽发出的单一叫声“隔离鸣叫”（isolation peep），检测了母亲的反应。播放的录音剪辑自当幼崽和母亲可以看到彼此但无法触碰时所录制的混合发声材料的录音带。与其他熟悉的幼崽相比，母亲在靠近扬声器的四个方面的行为增加，这表明她们能识别自己的幼崽。这些数据表明，当测试刺激物由具有个体差异的单一叫声类型的例子组成时，母亲通过声音线索识别幼崽是可能的。
