ONTOGENY & FUNCTION OF PRIMATE VOCAL SIGNATURES

SPID号：53 我们研究的一个主要焦点是猕猴尖叫的个体发育。这些 是声学上不同的呼声，可以在 竞技性相遇和编码关于对手的特定信息 (例如，它的相对优势度等级，就恒河猴而言， 它与呼叫者的关联性)以及攻击的强度。 为了让猴子使用上下文正确的调用，它必须具有 关于内部亲属关系和支配关系网络的知识 它的团体。听到呼唤的盟友也是如此。一致 有了这些要求，我们发现逐渐达到了熟练程度 具有尖叫声使用和生产的特点。个人声乐 对呼叫者的识别对于这一激励性的系统至关重要 招聘。发声很可能有多个参照物，我们的 对辫子猕猴尖叫声的分析揭示了声音特征的证据 这是母系亲属的特征，也许还可以用来识别 组。因此，除了尖叫提供的信息外， 外部竞争环境的特征，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。 潜在的灵长类竞争联盟形成和我们的证据 到了这样一个识别系统，在招聘的尖叫声中扎起了辫子 猕猴。正在进行的工作包括研究寄养家庭的尖叫声 和自然婴儿，试图确定发育的起源 这些声音签名。

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.
