SPID#: 53 A major focus of our research is the ontogeny of macaque screams. These are acoustically distinct calls that elicit support from allies during agonistic encounters and encode specific information about an opponent (such as its relative dominance rank and, in the case of rhesus macaques, its relatedness to the caller) as well as the intensity of the attack. In order for a monkey to use a contextually correct call, it must have knowledge of the network of kinship and dominance relationships within its group. The same is true for an ally hearing the call. Consistent with these requirements, we found gradual attainment of proficiency characterizes both scream usage and production. Individual vocal recognition of callers is critical to this system of agonistic recruitment. Vocalizations are likely to have multiple referents and our analyses of pigtail macaque screams revealed evidence of vocal signatures that characterize and, perhaps, serve to identify, matrilineal kin groups. Thus, in addition to the information screams provide about features of the external agonistic context, these calls can also convey information about kinship. Matrilineal kinship is often a major factor underlying primate agonistic alliance formation and our evidence points to such a recognition system in the recruitment screams of pigtail macaques. Ongoing work involves study of the screams of foster-reared and natural infants in an attempt to establish the developmental origins of these vocal signatures.

SPID编号：53 我们研究的一个主要焦点是猕猴尖叫的个体发生。 这些 是声音上不同的呼叫，在呼叫过程中， 对抗性的遭遇并编码关于对手的特定信息 (such作为其相对优势地位，在恒河猴的情况下， 其与呼叫者的相关性）以及攻击的强度。 为了让猴子使用上下文正确的呼叫，它必须 对内部亲属关系和支配关系网络的了解 其集团。 对于听到召唤的盟友来说也是如此。 一致 有了这些要求，我们发现， 这是使用和生产过程中的一个特点。 个人声乐 对呼叫者的识别对于这种竞争系统至关重要。 招聘 发声可能有多个参照物， 对猪尾猕猴尖叫声的分析显示， 这些特征也许可以用来识别母系亲属 组 因此，除了尖叫声提供的信息外， 外部对抗背景的特征，这些呼叫也可以传达 关于亲属关系的信息 母系亲属关系往往是一个主要因素 我们的证据表明， 到这样一个识别系统在招聘尖叫的辫子 猕猴 正在进行的工作包括研究寄养的尖叫声， 和自然婴儿，试图建立发展的起源 这些声音的特征。
