The human brain is fundamentally a social brain, with its perceptual and cognitive systems evolved to support a diverse set of processes aimed at enabling our complex social function. And while in the last decades the field has advanced considerably in understanding the mechanisms by which the perceptual and cognitive faculties support human social behaviour, there remains a lack of knowledge about social information is communicated between individuals. In my work, I have studied nonverbal visual social signalling via faces and eyes. In this article, I summarize the results from three lines of my research which show that (a) limiting face visibility decreases its social value, (b) eyes transmit key social messages, and (c) group size modulates social messages. Together, these data show that visual signals from faces and eyes convey complex social messages and represent an important vehicle for the communication of social information.

人类大脑从根本上说是一种社交大脑，其感知和认知系统进化的目的是支持一系列旨在实现我们复杂社交功能的过程。虽然在过去的几十年里，该领域在理解感知和认知能力支持人类社交行为的机制方面已经取得了相当大的进展，但对于个体之间如何传递社交信息仍然知之甚少。在我的工作中，我研究了通过面部和眼睛进行的非言语视觉社交信号。在本文中，我总结了我研究的三个方面的结果，这些结果表明：（a）限制面部可见度会降低其社交价值；（b）眼睛传递关键的社交信息；（c）群体规模调节社交信息。这些数据共同表明，来自面部和眼睛的视觉信号传达了复杂的社交信息，是传递社交信息的重要载体。
