Abstract

Social avoidance refers to the tendency to be alone and non-participating to social interactions, which is considered to hamper health interpersonal relationship. However, the neural underpinnings of social and emotional interactions among social avoidant individuals have not been fully studied. In the present study, we used EEG hyperscanning technology to investigate the brain activity and its synchronization of 25 socially avoidant dyads and 28 comparison dyads during an emotional communication task. The emotional communication task consisted of the emotional processing stage and emotional interaction stage. Event-related potentials (ERPs) of the senders during the emotional processing stage and the interbrain synchrony (IBS) of the dyads during the emotional interaction stage were analyzed. Results showed that (1) socially avoidant group showed higher beta, theta and gamma IBS in the negative condition than in the positive and neutral condition; (2) in positive condition, the N1 and LPP amplitudes during the emotional processing stage of socially avoidant individuals were negatively correlated with the IBS within dyads during the emotional communication stage. The findings suggest that the dysfunctional emotional interaction of social avoidant individuals may be attributed to the negative impact of emotional stimuli processing during emotional communication.

社交回避与渴望理解的悖论:社交回避者在表达负面情绪时脑间同步性升高
社交回避指的是倾向于独处和不参与社交互动,这被认为会妨碍健康的人际关系。然而,社交回避者的社交和情感互动的神经基础尚未得到充分研究。在本研究中,我们使用脑电图超扫描技术研究了 25 个社交回避者和 28 个对比者在情感交流任务中的大脑活动及其同步性。情感交流任务包括情感处理阶段和情感互动阶段。研究分析了情感处理阶段发送者的事件相关电位(ERP)和情感互动阶段双人的脑间同步(IBS)。结果显示:(1) 社交回避群体在消极状态下的β、θ和γ脑间同步电位高于积极和中性状态下的β、θ和γ脑间同步电位;(2) 在积极状态下,社交回避个体在情绪处理阶段的N1和LPP振幅与情感交流阶段的双人脑间同步电位呈负相关。研究结果表明,社交回避者的情感互动功能障碍可能是由于情感交流过程中情感刺激处理的负面影响造成的。
