摘要: 如何揭示情绪性面孔加工的认知神经机制一直是心理学和社会神经科学的热点课题。以往研究主要采用单独面孔表情作为情绪诱发或呈现方式,但对群体情绪知觉与体验的关注极其缺乏,而群体面孔表情作为群体情绪的主要表达方式,亟待深入关注。因此,本项目将采用群体面孔(面孔群)表情作为群体情绪刺激,拟通过事件相关电位(ERP)、核磁共振(fMRI)以及经颅磁刺激(TMS)等技术结合行为研究,尝试从情绪信息(效价、强度)、朝向信息(正面、侧面、倒置)、完整性(局部呈现、完整呈现)、空间频率信息(完整、高频、低频)等方面探明群体面孔表情加工的时间动态特征和大脑激活模式。这将有助于全面认识和深入了解群体情绪识别的一般规律,对于更好地优化社会互动也具有现实意义。

Abstract: How to reveal the cognitive neural correlates underlying emotional face processing has always been the popular topic for psychology and social neuroscience. Previous studies mainly used single facial expressions as the stimuli to induce and present emotions, whereas still lacking the interest and the investigation for the crowd emotion. Thus, the present project plans to reveal the neural correlates underlying the processing for crow emotional faces through the combination of behavioral, ERP, fMRI, and TMS experiments, in which the emotional information (valence and intensity), face direction (frontal, lateral and inverse view), integrity (partial presentation, complete presentation) and spatial frequency (complete, high frequency, low frequency) will be investigated to reveal the temporal dynamic characteristic and brain activation patterns of crowd facial expressions processing. Finally, our work will be expected to beneficially serve the comprehensive understanding of the general rule for the perception and recognition of crowd emotion, which is also of practical significance towards updating social interactions.

Key words: facial expression, emotional processing, crowd emotion, ensemble perception
