In social species, there is variation in the extent to which individuals within groups use the position or behaviors of those closest to them to inform their own behavior; this is called social responsiveness. While previous research has demonstrated that variation in social responsiveness among individuals in a group influences ways in which the whole group behaves, this research has been through work in laboratories or using computer simulations. In order to better understand this phenomenon and how it relates to the evolution of social behavior, this doctoral dissertation research project examines these relationships in natural settings. The investigators use new tracking technologies and advance the field of biological anthropology by introducing non-invasive, image-based techniques for tracking nonhuman primate movements and interactions in the wild. Through this project the investigators create opportunities for both masters’ and undergraduate thesis projects and develop new educational modules on collective animal behavior targeted toward middle-school students. Collective behavior researchers have proposed that socially responsive individuals follow cues given by neighbors to make inferences about environmental conditions and resource locations, while unresponsive individuals gather information privately through independent investigation of the environment. Theory predicts that the extent of within-group variation in social responsiveness produces group-level traits, such as cohesion and collective decision-making regimes, which in turn have consequences for individual fitness. This project has three specific objectives: (1) identify the contexts in which wild female savannah baboons are socially responsive; (2) examine if variation in social responsiveness affects collective behavior; and (3) test if group composition affects individual fitness according to its expected effects on collective movement. To achieve these objectives, novel data are collected in the field using 3D stereo videography and GPS-accelerometer collars. Long-term demographic and behavioral data collected over five decades of population monitoring are used to contextualize results. Furthermore, by considering the simultaneous “bottom-up” effects of individual variation on collective behavior and the “top-down” effects of collective behavior on individual fitness in a highly social primate, this project offers novel insight into the adaptive value of social responsiveness and its role in patterning group-level phenomena.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.

在社会物种中，群体内的个体利用最接近的人的位置或行为来告知自己的行为的程度存在差异，这被称为社会反应性，而先前的研究表明，个体之间的社会反应性存在差异。一个群体影响整个群体的行为方式，这项研究是通过实验室工作或使用计算机模拟进行的，为了更好地理解这种现象及其与社会行为进化的关系，本博士论文研究项目研究了这些关系。研究人员在自然环境中使用新的追踪技术。通过引入非侵入性、基于图像的技术来跟踪野外非人类灵长类动物的运动和相互作用，研究人员为硕士和本科生论文项目创造了机会，并开发了新的教育模块，从而推动了生物人类学领域的发展。针对中学生的集体动物行为。集体行为研究人员提出，具有社交反应的个体会根据邻居给出的线索来推断环境条件和资源位置，而反应迟钝的个体则通过对环境的独立调查来私下收集信息。程度群体内社会反应能力的差异会产生群体层面的特征，例如凝聚力和集体决策制度，这反过来又会对个体的适应性产生影响。该项目有三个具体内容：（1）确定野生雌性草原狒狒的生存环境。具有社会反应性；（2）检查社会反应性的变化是否影响集体行为；以及（3）根据其对集体运动的预期影响来测试群体组成是否影响个体适应性。 3D立体此外，通过考虑个体差异对集体行为和“自上而下”行为的同时“自下而上”的影响，使用录像和 GPS 加速计项圈收集了 50 年人口监测的长期人口和行为数据。在高度社会化的灵长类动物中，集体行为对个体适应性的“下降”影响，该项目为社会反应的适应性价值及其在群体层面现象模式中的作用提供了新颖的见解。该项目授予 NSF 的法定使命，并被认为值得通过以下方式支持：评估使用基金会的智力价值和更广泛的影响审查标准。
