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.
人际互动对浪漫情侣来说至关重要。了解性别如何在亲密互动过程中影响个体的大脑活动至关重要。本研究使用非侵入性功能性近红外光谱技术（fNIRS），考察了浪漫情侣成员在实时绘画互动过程中氧合血红蛋白（oxy-Hb）变化的性别差异。我们分析了参与互动（即追逐和逃避）和非互动（即单独）绘画环节的浪漫情侣的氧合血红蛋白浓度。我们的研究结果表明，在互动绘画任务中，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域表现出更明显的氧合血红蛋白浓度，这表明在社交互动中目标导向性参与度更高。颞叶区域的氧合血红蛋白量与关系质量指数（QRI）之间存在显著正相关，强调了人际动态在互动任务期间对大脑功能的影响。本研究加深了对社交互动任务中神经机制性别差异的理解，并为亲密关系研究提供了重要见解。
