The evolution of group-mindedness: Comparative perspectives with humans' evolutionarily and socially closest species

在本财年，我发表了3篇科学文章，在2次大型国际会议上发表了我的研究，并收集了几个新项目的数据。我能够分析我的自由范围的马匹GPS数据，发现催产素对群体组织的显著影响(群体分化减少，群体更分散)，并完成了从5个地点的8个矮黑猩猩群体收集数据，这是一个关于外群体发声对内群体社会行为影响的国际合作(发现矮黑猩猩在面对感觉到的外群体威胁时确实倾向于与其内部群体团结，但程度低于之前的研究中的黑猩猩)。我还使用眼神跟踪技术收集了通过社交亲近传递的眼神接触数据，积累了几个群体的观察数据，并使用无人机进行了一项新的马匹观察性研究(研究催产素如何影响空间组织以外的实际社交行为)。我还开始将这些研究汇编成一篇博士论文，准备在本财年毕业，其中的研究集中在支持在催产素系统的支持下，群体间威胁对某些形式的群体意识的作用。

In this fiscal year I published 3 scientific articles, presented my research at 2 large international conferences, and collected data on several new projects. I was able to analyze my free-ranging horse GPS data, finding significant effects of oxytocin on group organization (decreased group differentiation and more diffuse groups), as well as finishing collecting data from 8 bonobo groups at 5 sites in an international collaboration on the effect of outgroup vocalizations on ingroup social behaviour (finding bonobos do tend to unite with their ingroup in the face of perceived outgroup threat, but to a lesser degree than chimpanzees in the previous study). I also collected data on eye contact as mediated through social closeness using eye-tracking, accumulated observational data from several groups, and conducted a new horse observational study using drones to observe co-feeding (examining how oxytocin affects actual social behaviour beyond spatial organization). I also began to assemble the studies into a doctoral thesis to graduate this fiscal year, where the studies converge to support a role of intergroup threat on certain forms of group-mindedness as supported by the oxytocin system.
