This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. It is frequently hypothesized that primate cognition has evolved in response to selective pressures for the ability to process complex social information (e.g., Tomasello & Call, 1997). The social complexity hypothesis suggests that central insights into the structure and function of primate cognition will be achieved through the study of social cognition; however, few neurobehavioral studies of primate cognition have made use of social stimuli. There is therefore a critical need for studies of social cognition in primates. Historically, one of the issues retarding the development of such studies in monkeys is the difficulty in presenting animals with experimentally-controlled social stimuli. Our objective in this project is to develop a new behavioral paradigm for studying primate social cognition that permits reliable experimental control of social stimuli by using digitally-edited video clips of monkeys interacting. We have collected a library of primate social behavior videos at the field station using monkeys in Dr. Mark Wilson's laboratory. We have filmed 14 individual monkeys engaged in a variety of social behaviors and have edited many of these clips together to make realistic artificial social interactions. A group of 6 monkeys have been successfully trained to make dominance discriminations using these video clips. A variety of probe tests have revealed that the monkeys' performance is not controlled entirely by dominance information, however, and further probes are currently being run in an effort to determine what other information the monkeys may attend to in these videos. Other probes have demonstrated that the monkeys do remember individuals seen in the videos, and their relative rank.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 人们经常假设，灵长类动物的认知是为了应对处理复杂社会信息的能力的选择压力而进化的（例如，Tomasello & Call，1997）。社会复杂性假说认为，通过对社会认知的研究，可以对灵长类认知的结构和功能有更深入的了解;然而，很少有灵长类认知的神经行为研究利用社会刺激。因此，对灵长类动物社会认知的研究是非常必要的。从历史上看，阻碍在猴子中进行此类研究的问题之一是难以向动物提供实验控制的社会刺激。我们在这个项目中的目标是开发一种新的行为范式，用于研究灵长类动物的社会认知，通过使用数字编辑的猴子互动视频剪辑，允许可靠的实验控制社会刺激。 我们已经收集了一个图书馆的灵长类动物的社会行为的视频在外地站使用猴子在马克威尔逊博士的实验室。我们拍摄了14只猴子的各种社会行为，并将其中的许多片段编辑在一起，以制作逼真的人工社会互动。一组6只猴子已经成功地训练使用这些视频剪辑进行优势辨别。然而，各种探测测试表明，猴子的表现并不完全受优势信息的控制，目前正在进行进一步的探测，以确定猴子在这些视频中可能会注意到哪些其他信息。其他的研究表明，猴子确实记得在视频中看到的个体，以及它们的相对排名。
