Abstract

Interpersonal touch plays a key role in creating and maintaining affiliative pair bonds in romantic love. However, the neurocognitive mechanism of interpersonal touch in affiliative pair bonding remains unclear. Here, we hypothesized that interpersonal neural synchronization (INS) during interpersonal touch underlies affiliative pair bonding between romantic couples. To test this hypothesis, INS between heterosexual romantic couples and between opposite-sex friends was measured using functional near-infrared spectroscopy-based hyperscanning, while the pairs of participants touched or vocally communicated with each other. The results showed significantly greater INS between the mentalizing and sensorimotor neural systems of two members of a pair during interpersonal touch than during vocal communication between romantic couples but not between friends. Moreover, touch-induced INS was significantly correlated with the self-reported strength of romantic love. Finally, the results also showed that men's empathy positively modulated the association between touch-induced INS increase and the strength of romantic love. These findings support the idea that INS during interpersonal touch underlies affiliative pair bonding between romantic couples and suggest that empathy plays a modulatory role in the neurocognitive mechanism of interpersonal touch in affiliative pair bonding. © The Author(s) 2020.

人际交往在建立和维持恋爱关系中的亲密关系中起着关键作用。然而,人与人之间的联系在联结配对中的神经认知机制仍然不清楚。在这里,我们假设在人际交往过程中的人际神经同步(INS)是浪漫情侣之间的亲和关系的基础。为了检验这一假设,使用基于功能的近红外光谱的超扫描技术测量了异性恋浪漫情侣之间以及异性朋友之间的INS,而成对的参与者彼此接触或语音交流。结果表明,在人与人之间的接触中,一对两个成员的心理和感觉运动神经系统之间的INS比在浪漫情侣之间(而不是朋友之间)的语音交流过程中更大。此外,触摸诱导的INS与自我报告的浪漫爱情强度显着相关。最后,结果还表明,男人的同理心积极调节了触摸诱导的INS增加与浪漫爱情强度之间的关联。这些发现支持这样的想法,即在人际交往过程中,INS是浪漫情侣之间的亲属配对关系的基础,并表明同理心在亲属配对中的人际交往的神经认知机制中起调节作用。 ©2020作者。牛津大学出版社出版。版权所有。有关权限,请发送电子邮件至:journals.permissions@oup.com。
