在发育的过程中，新热带蝙蝠的幼崽似乎适应了它们的孤立叫声，以适应它们母亲的指示叫声的声音特征。然而，在受控的实验条件下，迄今为止，除了人类之外，还没有发现任何陆生哺乳动物具有听觉-声乐学习能力。在目前的研究中，一组蝙蝠幼崽在没有同种鸣叫的情况下被人工饲养，而一种不变的、数字化存储的母指令鸣叫在每次喂食前反复呈现给第二组的幼崽。与未受刺激的对照组相比，回放组的动物适应了这种外部声学参考信号的隔离呼叫结构。
IN the course of development, pups of the neotropical bat Phyllostomus discolor seem to adapt their isolation calls to the vocal signature of their mother's directive calls. Under controlled experimental conditions however, audio-vocal learning so far has not been demonstrated in any terrestrial mammal except man. In the present study one group of bat pups was hand-reared in the absence of conspecific vocalizations, whereas an unvarying, digitally stored maternal directive call was repeatedly presented to the juveniles of a second group prior to each feeding. In contrast to the unstimulated controls, the animals of the playback group adapted their isolation call structure to this external acoustic reference signal.
