In recent years, researchers have used hyperscanning techniques to explore how brains interact during various human activities. These studies have revealed a phenomenon called interpersonal neural synchronization (INS), but little research has focused on the overall effect of INS in close relationships. To address this gap, this study aims to synthesize and analyze the existing literature on INS during social interactions in close relationships. We conducted a meta-analysis of 17 functional near-infrared spectroscopy (fNIRS) hyperscanning studies involving 1149 dyads participants, including romantic couples and parent-child dyads. The results revealed robust and consistent INS in the frontal, temporal, and parietal regions of the brain and found similar INS patterns in couples and parent-child studies, providing solid empirical evidence for the attachment theory. Moreover, the age of children and brain areas were significant predictors of the effect size in parent-child research. The developmental stage of children and the mismatched development of brain structures might be the crucial factors for the difference in neural performance in social and cognitive behaviors in parent-child dyads.
近年来，研究人员利用超扫描技术来探索大脑在各种人类活动中的相互作用。这些研究揭示了一种称为人际神经同步（INS）的现象，但很少有研究关注 INS 在亲密关系中的整体影响。为了解决这一差距，本研究旨在综合和分析亲密关系中社交互动期间 INS 的现有文献。我们对涉及 1149 对参与者的 17 项功能性近红外光谱（fNIRS）超扫描研究进行了荟萃分析，包括浪漫伴侣和亲子对。结果显示，大脑的额、颞和顶叶区域存在强烈而一致的 INS，并且在夫妻和亲子研究中发现了相似的 INS 模式，为依恋理论提供了坚实的经验证据。此外，儿童的年龄和大脑区域是亲子研究中效应大小的显著预测因素。儿童的发展阶段和大脑结构的不匹配发展可能是亲子对子中社会和认知行为神经表现差异的关键因素。
