Abstract

Interpersonal interaction is essential to romantic couples. Understanding how gender impacts an individual's brain activities during intimate interaction is crucial. The present study examined gender differences in oxyhemoglobin (oxy-Hb) changes during real-time drawing interactions between members of romantic couples using non-invasive functional near-infrared spectroscopy (fNIRS). We analyzed the oxy-Hb concentrations of romantic couples engaged in interactive (i.e., chase and escape) and non-interactive (i.e., individual) drawing sessions. Our findings indicated that males (vs. females) exhibited more pronounced oxy-Hb concentrations in Broca's area, motor area, sensorimotor cortex, and temporal lobe areas than women in an interactive drawing task, suggesting a heightened goal-oriented engagement in social interaction. Significant positive correlations were found between oxy-Hb volumes of the temporal area and the Quality of Relationship Index (QRI), underscoring the impact of interpersonal dynamics on brain function during interactive tasks. This study deepens the understanding of gender differences in neural mechanisms in social interaction tasks and provides important insights for intimacy research.

人际交往对于浪漫的情侣来说至关重要。了解性别如何影响个体在亲密互动中的大脑活动至关重要。本研究利用无创功能性近红外光谱（fNIRS）检测了浪漫情侣之间实时绘画互动过程中氧血红蛋白（oxy-Hb）变化的性别差异。我们分析了恋爱情侣在互动（即追逐和逃避）和非互动（即单独）绘画过程中的氧血红蛋白浓度。我们的研究结果表明，在交互式绘画任务中，男性（与女性相比）在布罗卡区、运动区、感觉运动皮层和颞叶区的血氧浓度比女性更明显，这表明在社会交往中以目标为导向的参与度更高。研究还发现，颞叶区的氧-血红蛋白量与 "关系质量指数"（QRI）之间存在显著的正相关，这凸显了互动任务中人际动态对大脑功能的影响。这项研究加深了人们对社会互动任务中性别神经机制差异的理解，并为亲密关系研究提供了重要启示。
