摘　　要：超扫描技术可同时记录多名被试在同一认知活动中的脑活动,并通过分析脑间活动同步及其与行为指标间的关系描述社会互动的脑机制。本文总结了近十多年超扫描研究对社会互动脑机制的研究成果,在其基础上指出脑间活动同步可作为社会互动的神经标记,刻画社会互动中感知运动、信息传递与加工、思维决策等三大层面上的互动情形,并阐述了超扫描技术研究的局限性及其研究展望与应用潜能。Hyperscanning approach is a type of neuroimaging technique. It refers to the measuring of neural activities simultaneously from two or more agents involved in the same social interactions. Then inter-brain coupling(or interpersonal neural synchronization, INS) is analyzed and used to explain brain-to-brain neural correlates of social interactions in the perspective of group level. During the past decade, hyperscanning approach has become more and more popular, and has been a powerful approach to elucidate intrinsic property of higher cognition with social interactions in condition of higher ecological validity, such as cooperation/competition, behavioral synchrony/imitation, interpersonal communication and economic decision-makings, etc. In this paper, we first review and summarize the previous hyperscanning studies over the past decade, which are followed by limitations and future studies on other research fields with social interaction.First, stronger interpersonal neural synchronization(INS) emerges in prefrontal cortex(PFC) and/or right temporal-parietal junction(TPJ) with better coordination performances during singing, instrument playing and game of charades. More interestingly, several pieces of evidence show INS is correlated with the empathy and shared knowledge. Second, enhanced prefrontal INS is also observed in the interpersonal communication task(faceto-face verbal communication task, emotional transmission and so on). Further, INS can predict verbal and/or non-verbal communication quality, such as teacher-student interactions during teaching, leader emergence during a non-leader group discussion task. Third, enhanced INS is consistently obtained in PFC and/or TPJ during two participants performing both the concurrent cooperation task(such as joint key-press task) and the turn-taking cooperation/competition task(such as disk-game task), while no or much lower INS is found in control conditions. Such evidence indicates that INS can serve as a neuromarker to depict the cooperation and competition behav
