Abstract:

The shared experience of social exclusion promotes cooperation, but the neural mechanisms, particularly interpersonal ones, are unclear. In the present study, 82 female participants (41 pairs) were recruited to investigate the effects of shared experience of social exclusion on the cooperative tendency from an interbrain perspective using cyberball and prisoner’s dilemma paradigm. The results showed that the group who experienced shared social exclusion significantly exhibited higher level of cooperative tendency and increased interpersonal brain synchronization (IBS) in the right medial prefrontal gyrus(r-MFG) compared to the control group. Furthermore, a significant positive correlation was observed between cooperative tendency and IBS in the r-MFG. This suggests that the increase in the r-MFG IBS during cooperation may be an interbrain neural mechanism for increasing the cooperative tendency through the shared experience of social exclusion. This finding provides new evidence for understanding the interbrain neural basis of cooperative behaviour which provides implications for team management.

Key words: social exclusion, cooperative tendency, fNIRS, hyperscanning, interpersonal brain synchronization (IBS)

摘要:

共同经历社会排斥促进合作,但其神经机制并不清楚,尤其是人际神经机制。本研究招募女性被试82名(41对),采用网络掷球及囚徒困境范式,从双脑视角考察共同经历社会排斥对合作倾向的影响。结果显示,共同经历社会排斥组的合作倾向及右侧额中回脑间同步性均显著高于控制组;并且,右侧额中回脑间同步性与合作倾向显著正相关。这表明合作过程中,右侧额中回脑间同步性的提高,可能是共同经历社会排斥提高合作倾向的脑间神经机制。这一发现为理解合作行为的脑间神经基础提供了新证据,对团队管理具有一定借鉴意义。
