This project will test experimentally a set of hypotheses about monkeys' social knowledge and decisionmaking criteria. One set of experiments will focus on the issue of tactical deception-a phenomenon that has been well documented among apes and some Old World monkeys but virtually never reported in New World primates. Specifically, white-faced capuchins, a New World primate species, will be tested to see whether they find alarm calls less credible when they follow a simulated social situation in which the alarm caller would have a motive to deceive-specifically, a motive to distract the attention of higher-ranking monkeys engaged in an aggressive coalition against him or her. The other set of experiments will focus on the criteria involved in males' decisions about whether to respond aggressively to vocal threats by extra-group males. The project builds on the knowledge that has been gained in observational studies by using playbacks of vocalizations. The investigator will spend several months in Costa Rica conducting observations and collecting the recordings needed for conducting playback experiments. The social relationships and social cognition of capuchin monkeys are an interesting domain of inquiry because of current interest in the evolution of primate intelligence. Capuchins have the largest brains, relative to their bodies, of any nonhuman primates and therefore represent a key data point in the debate about whether the principal driving force behind primate brain expansion was selective pressure for spatial memory and extractive foraging dexterity or for the ability to solve complex social problems. This project will contribute valuable data on social cognition and social relationships in New World primate species that can be compared to the already extensive array of data on such issues in Old World primates. This award will enable the investigator to learn new technical skills, specifically bioacoustic analysis and playback experiment protocols. It will also provide funds for the investigator to conduct experiments to test the feasibility of her approach to the study of the evolution of intelligence.

这个项目将通过实验测试一系列关于猴子的社会知识和决策标准的假设。 一组实验将集中在战术欺骗的问题上--这种现象在猿和一些旧大陆的猴子中有很好的记录，但在新大陆的灵长类动物中几乎从未报道过。 具体来说，白脸卷尾猴，一种新大陆灵长类动物，将被测试，看看他们是否发现报警电话不太可信时，他们遵循一个模拟的社会情况下，报警电话将有动机欺骗-具体来说，动机是为了分散上级的注意力另一组实验将集中在雄性决策的标准上关于是否要积极回应来自群体外雄性的威胁。 该项目建立在观察研究中通过使用发声回放获得的知识基础上。 调查员将在哥斯达黎加进行几个月的观察，并收集进行回放实验所需的录音。 卷尾猴的社会关系和社会认知是一个有趣的研究领域，因为目前对灵长类动物智力进化的兴趣。 卷尾猴的大脑相对于它们的身体来说是所有非人类灵长类动物中最大的，因此在关于灵长类动物大脑扩张背后的主要驱动力是空间记忆和提取觅食灵活性的选择性压力还是解决复杂社会问题的能力的争论中，卷尾猴代表了一个关键的数据点。 该项目将为新世界灵长类动物的社会认知和社会关系提供有价值的数据，这些数据可以与旧世界灵长类动物在这些问题上已经广泛的数据进行比较。 该奖项将使研究人员能够学习新的技术技能，特别是生物声学分析和回放实验协议。 它还将为研究人员提供资金进行实验，以测试她研究智力进化的方法的可行性。
