The ability to determine gaze direction is vital to many social behaviors. This project will study the morphological factors influencing individuals' abilities to detect gaze direction. Using human and nonhuman primates in a comparative framework, the researchers will study the relationship between eye morphology and gaze perception. The research will provide a better understanding of how the appearance of the eye influences gaze perception across the primate lineage. Outreach activities will include the project team giving interactive presentations on primate behavior and conservation to high school students and community members, with a particular focus on students and community members belonging to groups underrepresented in STEM fields. The project will also develop a primate behavior module at an under-resourced high school; the students will learn about primates and conduct observational studies at a local zoo. The team will train a postdoctoral associate, as well as undergraduate students, in primate behavior, conservation, and management.Gaze perception is of fundamental importance to social cognition but our understanding of the ways in which eye morphology impacts it is limited. This project will examine the relationship between gaze perception and eye morphology to determine whether conspicuous eye morphology facilitates gaze perception while inconspicuous eye morphology conceals gaze perception. It will manipulate eye morphology and examine its impact on gaze perception in humans as well as other primates. After presenting subjects with photographic arrays of faces that have systematically manipulated eye morphology, it will instruct subjects to detect faces with specific gaze directions. It will monitor the eye movements of subjects to track their gaze behavior during the task. The results of this study will help elucidate the evolutionary significance of eye morphology on gaze perception across primate species.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

确定凝视方向的能力对许多社会行为至关重要。本项目将研究影响个体检测凝视方向能力的形态学因素。研究人员将在比较框架中使用人类和非人类灵长类动物，研究眼睛形态和凝视感知之间的关系。这项研究将更好地理解眼睛的外观如何影响灵长类动物的凝视感知。外展活动将包括项目团队向高中生和社区成员进行关于灵长类动物行为和保护的互动演讲，特别关注属于STEM领域代表性不足群体的学生和社区成员。该项目还将在一所资源不足的高中开发一个灵长类动物行为模块；学生们将学习灵长类动物，并在当地动物园进行观察研究。该团队将在灵长类动物行为、保护和管理方面培训一名博士后助理和本科生。凝视感知对社会认知至关重要，但我们对眼睛形态影响凝视感知的方式的理解有限。本项目将研究凝视感知与眼睛形态之间的关系，以确定是否显眼的眼睛形态促进了凝视感知，而不显眼的眼睛形态掩盖了凝视感知。它将操纵眼睛形态，并研究其对人类和其他灵长类动物凝视感知的影响。在向受试者展示经过系统操作的眼睛形态的面部照片阵列后，它将指导受试者检测具有特定凝视方向的面部。它将监测受试者的眼球运动，追踪他们在任务过程中的注视行为。本研究结果将有助于阐明眼形态对灵长类动物凝视感知的进化意义。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
