Unexpected acute stressors may affect our co-representation with other co-actors when completing the joint tasks. The present study adopted the emergent functional near-infrared spectroscopy (fNIRS)-based hyperscanning method to explore the brain-to-brain synchrony when implementing the Joint Simon Task under acute stress induced in the laboratory. The behavioral results reported that the joint Simon effect (JSE) was found in both the stress group and the control group, but the joint Simon effect in the stress group was significantly lessened than the joint Simon effect in the control group, demonstrating that when completing the joint action task in the state of acute stress, women's ability to distinguishing self- from other-related mental representations was improved, and the strength of women's action co-representation was diminished. The fNIRS results showed that when completing the joint Simon task in the state of the acute stress, the brain-to-brain synchrony at the r-TPJ in the stress group was significantly higher than that in the control group, demonstrating that the increased brain-to-brain synchrony at the TPJ may be served as the critical brain-to-brain neural mechanism underlying the joint action task under acute stress.
意外的急性应激源可能会在我们与其他合作者完成联合任务时影响我们的共同表征。本研究采用基于功能性近红外光谱（fNIRS）的超扫描方法，以探究在实验室诱导的急性应激下执行联合西蒙任务时的脑间同步情况。行为结果表明，应激组和对照组均发现了联合西蒙效应（JSE），但应激组的联合西蒙效应明显小于对照组，这表明在急性应激状态下完成联合动作任务时，女性区分自我与他人相关心理表征的能力得到了提高，且女性动作共同表征的强度减弱。fNIRS结果显示，在急性应激状态下完成联合西蒙任务时，应激组r-TPJ处的脑间同步显著高于对照组，这表明TPJ处脑间同步的增加可能是急性应激下联合动作任务潜在的关键脑间神经机制。
