Abstract

Emotional attunement, or emotional co-regulation in a relationship, can manifest as interpersonal neural synchrony, where partners exhibit similar anti-phase or phase-shifted brain activity. In adult romantic relationships, emotional attunement may differ according to relationship satisfaction. No study has examined how relationship satisfaction difference influences interpersonal neural synchrony. This exploratory pilot study on 17 couples (unmarried Chinese undergraduate couples in a Southeast Asian university) investigated whether relationship satisfaction difference influenced interpersonal neural synchrony during a shared emotive experience. Each couple wore an fNIRS cap to measure brain activity in their prefrontal cortex (PFC) while co-viewing seven videos intended to evoke positive, negative or neutral emotions. We found preliminary evidence that relationship satisfaction difference modulated interpersonal neural synchrony in the right ventral PFC regions, including the right ventromedial PFC (involved in the encoding of emotional values to stimuli and emotional regulation), right ventrolateral PFC (involved in voluntary emotional regulation) and the right orbitofrontal cortex (involved in processing of emotional experiences and regulation of emotions). This suggested that couples with mismatched relationship satisfaction displayed greater interpersonal neural synchrony, possibly due to mutual social cognitive processes when viewing emotive videos together. Further studies can replicate the findings with larger, diverse samples.

关系满意度不匹配的恋人在共同观看情感视频时表现出更大的人际神经同步性:一项探索性试点fNIRS超扫描研究。
情感调节,或情感共同调节在一段关系中,可以表现为人际神经同步,其中伴侣表现出类似的反相位或相移的大脑活动。在成人的恋爱关系中,情感调节可能会根据关系满意度而有所不同。目前还没有研究考察关系满意度差异对人际神经同步的影响。本研究以17对夫妇(东南亚一所大学的未婚中国本科生夫妇)为研究对象,探讨了在共同情感体验中,关系满意度差异是否影响人际神经同步。每对夫妇都戴着fNIRS帽子来测量他们前额叶皮层(PFC)的大脑活动,同时共同观看七段旨在唤起积极、消极或中性情绪的视频。我们初步发现,关系满意度差异调节了右腹侧PFC区域的人际神经同步,包括右腹内侧PFC区域(参与刺激的情绪价值编码和情绪调节)、右腹外侧PFC区域(参与自愿情绪调节)和右眶额皮质区域(参与情绪体验加工和情绪调节)。这表明,关系满意度不匹配的夫妻表现出更大的人际神经同步性,这可能是由于在一起观看情感视频时相互的社会认知过程。进一步的研究可以用更大、更多样化的样本来复制这些发现。
