日本猕猴（Macaca fuscata）和对照物种（长尾猕猴，长尾猕猴，帽猴）接受食物训练，对一种记录的fuscata叫声有反应，对第二种叫声没有反应。通过将刺激随机呈现给右耳或左耳，并比较两耳的表现（耳优势法）来测量神经侧化。声音来自史蒂文·格林的现场磁带。在实验1中，两个班级分别为Green' s“光滑的早高coos”（SE）和“光滑的晚高coos”（SL）。实验二使用了相同的发声方式，但分为高音和低音两类，即与交流相关的维度垂直。我们发现(a)日本猕猴学习SE-SL辨别比学习音高辨别快；(b)对照组的情况正好相反；(c)日本猕猴在辨别SE-SL时表现出右耳优势（假定为左半球优势），而在辨别音高时则不表现出右耳优势；(d)对照组（除一个例外）在辨别这两种声音时都不表现出耳朵优势。这些对同类型发声的交流相关参数的选择性注意，以及对这些发声的感知中的神经侧化的证明，与人类语言感知中的类似发现相似。
Japanese macaques(Macaca fuscata)and control species (vervet, pigtailed macaque, bonnet macaque) were trained for food to respond to one class of recorded fuscata vocalizations and to not respond to a second class. A measure of neural lateralization was obtained by presenting the stimuli randomly to the right or the left ear, and comparing performance in the two ears (ear advantage method). Vocalizations were from Steven Green''s field tapes. In experiment I, the two classes were Green''s ''smooth early high coos'' (SE) and ''smooth late high coos'' (SL). Experiment II utilized the same vocalizations, but sorted into a high-pitched and a low-pitched class, i.e., orthogonally to the communication-relevant dimension. We found that (a) Japanese macaques learned the SE-SL discrimination faster than the pitch discrimination; (b) the reverse was true for the controls; (c) Japanese macaques showed a right-ear advantage (presumed left hemisphere advantage) for the SE-SL distinction, but not for the pitch discrimination, and (d) controls (with one exception) showed no ear advantage for either discrimination. These demonstrations of selective attention to communication-relevant parameters of conspecific vocalizations, and neural lateralization in the perception of these vocalizations, parallel similar findings in human speech perception.
