摘要： 通过同时记录社会互动中多名个体的脑信号，超扫描研究普遍观测到个体间脑活动信号的同步性（inter-brain synchronization, IBS）。然而，如何解释IBS是研究者面临的普遍问题。本文总结了IBS的含义和度量方法，分析了产生IBS的驱动因素、认知机制和其神经生理学基础。我们提出IBS主要受互动类型与强度、任务情境、人际关系、个体特征与状态的影响，并推测IBS在人际动作协调、语言交流和建立社会联结方面具有功能性意义。后续研究可深入探究“共同表征”与“相互预测”机制的关系、人际“去同步”、跨脑可塑性和不同交互形式的异同等问题。

Abstract: By simultaneously recording brain signals from multiple individuals during interpersonal communication, hyperscanning studies have consistently observed inter-brain synchronization (IBS). However, the interpretation of IBS remains challenging. In this paper, we analyze the driving factors, cognitive mechanism and neurophysiological basis of inter-brain synchronization, and point out that inter-brain synchronization is mainly affected by interaction type and intensity, task context, partnership, individual characteristics and states, and speculate that inter-brain synchronization has functional significance in interpersonal motor coordination, verbal communication and social bonding. Further research can explore the relationship between "co-representation" and "mutual prediction" mechanisms, interpersonal "de-synchronization", cross-brain plasticity, and the comparison of different forms of interaction.
