Chen, Zhang, Zhang, Wang, Yin, Li, Liu, Liu, Li (2020) Neural alignment during face-to-face spontaneous deception: Does gender make a difference? Human brain mapping 41(17) 4964-4981
This study investigated the gender differences in deception and their neural basis in the perspective of two-person neuroscience. Both male and female dyads were asked to perform a face-to-face spontaneous sender-receiver deception task, while their neural activities in the prefrontal cortex (PFC) and right temporal parietal junction (rTPJ) were recorded simultaneously using functional near-infrared spectroscopy (fNIRS)-based hyperscanning. Male and female dyads displayed similar deception rate, successful deception rate, and eye contact in deception trials. Moreover, eye contact in deception trials was positively correlated with the success rate of deception in both genders. The fNIRS data showed that the interpersonal neural synchronization (INS) in PFC was significantly enhanced only in female dyads when performed the deception task, while INS in rTPJ was increased only in male dyads. Such INS was correlated with the success rate of deception in both dyads. Granger causality analysis showed that no significant directionality between time series of PFC (or rTPJ) in each dyad, which could indicate that sender and receiver played equally important role during deception task. Finally, enhanced INS in PFC in female dyads mediated the contribution of eye contact to the success rate of deception. All findings in this study suggest that differential patterns of INS are recruited when male and female dyads perform the face-to-face deception task. To our knowledge, this is the first interbrain evidence for gender difference of successful deception, which could make us a deeper understanding of spontaneous face-to-face deception. © 2020 The Authors.

本研究从两人神经科学的角度研究了欺骗的性别差异及其神经基础。男性和女性二元组都被要求执行面对面的自发发送者-接收者欺骗任务，同时使用功能近红外光谱法同时记录他们在前额叶皮层（PFC）和右颞顶叶连接（rTPJ）中的神经活动。基于（fNIRS）的超扫描。在欺骗试验中，男性和女性二元组显示出相似的欺骗率，成功欺骗率和目光接触。此外，欺骗试验中的眼神交流与两种性别的欺骗成功率均呈正相关。 fNIRS数据显示，执行欺骗任务时，PFC中的人际神经同步（INS）仅在女性双胞胎中显着增强，而rTPJ中的INS仅在男性双胞胎中增加。这样的INS与两个双子中的欺骗成功率相关。 Granger因果关系分析表明，在每个对偶中，PFC（或rTPJ）的时间序列之间没有明显的方向性，这可能表明发送方和接收方在欺骗任务中起着同等重要的作用。最后，雌性二元组PFC中增强的INS介导了眼神交流对欺骗成功率的贡献。这项研究中的所有发现表明，当男性和女性二元组执行面对面的欺骗任务时，会募集不同的INS模式。据我们所知，这是成功欺骗的性别差异的第一个人际关系证据，这可以使我们对自发的面对面欺骗有更深的了解。 ©2020作者。人脑图谱由Wiley Periodicals LLC发布。
