Previous studies on the brain-brain interaction of deception have shown different patterns of interpersonal brain synchronization (IBS) between different genders. However, the brain-brain mechanisms in the cross-sex composition need to be better understood. Furthermore, there needs to be more discussion about how relationships (e.g., romantic couples vs. strangers) affect the brain-brain mechanism under interactive deception. To elaborate on these issues, we used the functional near-infrared spectroscopy (fNIRS)-based hyperscanning approach to simultaneously measure interpersonal brain synchronization (IBS) in romantic couples (heterosexual) and cross-sex stranger dyads during the sender-receiver game. The behavioral results found that the deception rate of males was lower than that of females, and romantic couples were deceived less than strangers. Significantly increased IBS was observed in the frontopolar cortex (FPC) and right temporoparietal junction (rTPJ) of the romantic couple group. Moreover, the IBS is negatively correlated with the deception rate. No significantly increased IBS was observed in cross-sex stranger dyads. The result corroborated the lower deception of males and romantic couples in cross-sex interactions. Furthermore, IBS in the PFC and rTPJ was the underlying dual-brain neural basis for supporting honesty in romantic couples.
以往关于欺骗的脑-脑交互研究表明，不同性别之间存在不同模式的人际脑同步（IBS）。然而，跨性别组合中的脑-脑机制仍需深入了解。此外，对于关系（如浪漫情侣与陌生人）如何在互动欺骗下影响脑-脑机制，还需要更多讨论。为详细阐述这些问题，我们采用基于功能近红外光谱（fNIRS）的超扫描方法，在发送者-接收者游戏过程中，同时测量浪漫情侣（异性恋）和跨性别陌生二人组的人际脑同步（IBS）。行为结果发现，男性的欺骗率低于女性，浪漫情侣比陌生人更不容易受骗。在浪漫情侣组的额极皮层（FPC）和右侧颞顶联合区（rTPJ）观察到IBS显著增加。此外，IBS与欺骗率呈负相关。在跨性别陌生二人组中未观察到IBS显著增加。该结果证实了在跨性别互动中男性和浪漫情侣的欺骗行为较少。此外，前额叶皮层（PFC）和rTPJ中的IBS是支持浪漫情侣诚实行为的潜在双脑神经基础。
