对手势和发声的复杂分析，包括对其情感效价的评估，有助于群居灵长类动物有效地驾驭他们的社会环境。社会信息处理和情绪调节的缺陷是许多人类精神疾病的重要组成部分，如自闭症，精神分裂症和社交焦虑症。分析社会信息处理和情绪调节的神经生物学需要多学科的方法，从人类和动物模型的比较研究中受益。然而，在处理社会刺激时，视觉注意和唤醒之间的关系仍然存在许多问题。使用非侵入性红外眼动跟踪方法，我们测量了成年雄性恒河猴（Macaca mulatta）观看社交和非社交视频时的视觉社会注意力和生理唤醒（瞳孔直径）。我们发现，与非社交视频相比，社交视频能吸引更多的视觉注意力，特别是如果视频中描绘的社交信号是针对对象的。主题为导向的社会线索和非社会性质的纪录片镜头，相比，视频显示同种从事自然主义的社会互动，产生较大的瞳孔直径（表明提高交感神经唤醒）。这些发现表明，恒河猴会积极参与观看各种视频。此外，红外眼动跟踪技术提供了一种机制，用于灵敏地测量所呈现的刺激的社会兴趣。成年雄性恒河猴的视觉注意和生理唤醒并不总是朝着同一个方向发展，并且可能受到特定视觉刺激的内容和新奇的影响。这项实验为未来的实验奠定了坚实的基础，这些实验将研究非人类灵长类动物中负责社会信息处理的神经网络。这些研究可能提供有价值的信息，解释人类精神疾病，如自闭症，精神分裂症和社交焦虑症的神经缺陷。
The sophisticated analysis of gestures and vocalizations, including assessment of their emotional valence, helps group-living primates efficiently navigate their social environment. Deficits in social information processing and emotion regulation are important components of many human psychiatric illnesses, such as autism, schizophrenia and social anxiety disorder. Analyzing the neurobiology of social information processing and emotion regulation requires a multidisciplinary approach that benefits from comparative studies of humans and animal models. However, many questions remain regarding the relationship between visual attention and arousal while processing social stimuli. Using noninvasive infrared eye-tracking methods, we measured the visual social attention and physiological arousal (pupil diameter) of adult male rhesus monkeys (Macaca mulatta) as they watched social and nonsocial videos. We found that social videos, as compared to nonsocial videos, captured more visual attention, especially if the social signals depicted in the videos were directed towards the subject. Subject-directed social cues and nonsocial nature documentary footage, compared to videos showing conspecifics engaging in naturalistic social interactions, generated larger pupil diameters (indicating heightened sympathetic arousal). These findings indicate that rhesus monkeys will actively engage in watching videos of various kinds. Moreover, infrared eye tracking technology provides a mechanism for sensitively gauging the social interest of presented stimuli. Adult male rhesus monkeys' visual attention and physiological arousal do not always trend in the same direction, and are likely influenced by the content and novelty of a particular visual stimulus. This experiment creates a strong foundation for future experiments that will examine the neural network responsible for social information processing in nonhuman primates. Such studies may provide valuable information relevant to interpreting the neural deficits underlying human psychiatric illnesses such as autism, schizophrenia and social anxiety disorder.
