Dissertation Research: The Role of Huh Vocalization in the Foraging Behavior of the Wedge-Capped Capuchin (Cebus Olivaceus)

非人灵长类动物语音交流的研究对于理解人类的言语和意识有着重要的意义。猴子发声经常传递特定信息，这一发现为人类语言能力的进化提供了重要的见解。本项目研究委内瑞拉楔帽卷尾猴(Cebus Olivaceus)最频繁发声的功能。发声的意义将通过记录觅食过程中发出的叫声，并将叫声的声学结构与行为背景相关联来确定。分析将集中在这些呼叫是否告知听者发声者的身份或状态，这些呼叫与不同类型的食物资源的使用如何相关，以及这些呼叫如何表明社会关系。除了提供关于尚未被广泛研究的一种叫声--安静叫声的信息外，该项目还将是第一次在河边森林以外的栖息地对楔冠卷尾猴的行为和饮食进行长期研究。因此，它将提供关于这种适应能力最强、最聪明的新大陆猴子的社会行为和生态的补充信息。

The study of vocal communication in non-human primates has significant implications for the understanding of human speech and consciousness. The discovery that monkey vocalizations frequently communicate specific information has provided important insights into the evolution of human language ability. This project investigates the function of the most frequent vocalization used by the Venezuelan wedge-capped capuchin monkey (Cebus olivaceus). The meanings of the vocalization will be determined by recording calls made during foraging for food and correlating the acoustic structure of the calls with the behavioral context. Analysis will focus on whether the calls inform listeners of the identity or status of the vocalizer, how the calls are related to the use of different types of food resources, and how the calls indicate social relationships. In addition to providing information about a category of call, quiet calls, that has not been extensively studied, this project will be the first long-term study of the behavior and diet of the wedge-capped capuchin to be carried out in a habitat other than riverine forest. As such, it will supply added information about the social behavior and ecology of this most adaptable and intelligent New World monkey.
