Shared Experience of Social Exclusion Increases Female's Cooperative Tendency:An fNIRS-Based Hyperscanning Study
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.
