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

在这个财政年度，我发表了3篇科学文章，在2个大型国际会议上介绍了我的研究，并收集了几个新项目的数据。我能够分析我的自由放养的马的GPS数据，发现催产素对群体组织的显着影响（群体分化减少，群体更加分散），以及完成了在5个地点收集8个倭黑猩猩群体数据的工作，这是一项关于外群体发声对内群体社会行为影响的国际合作（发现倭黑猩猩在面对感知到的外群威胁时确实倾向于与其内群联合，但程度低于先前研究中的黑猩猩）。我还收集了通过使用眼动跟踪的社交亲密度介导的眼神接触数据，从几个群体中积累了观察数据，并使用无人机进行了一项新的马观察研究，以观察共同喂养（研究催产素如何影响空间组织之外的实际社会行为）。我也开始将这些研究整理成一篇博士论文，准备在本财年毕业。在论文中，这些研究都支持群体间威胁在某些形式的群体意识中的作用，催产素系统也支持这种作用。

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.
