Effects Of Perceived Social Mindfulness On Cooperative Performance And Interpersonal Neural Synchronization In Female College Students

Cooperation refers to the behavior of two or more individuals or groups that coo perate and cooperate with each other for common,mutual or some potential benefits^[1].From the perspective of hyperscanning,the factors affecting cooperative behavior inc lude individual characteristics,task setting and task environment.However,the hypersca nning study has not focused on the influence of the donor's behavior on the partner's behavior.It has been found from behavioral research that perception of social mindful ness affects cooperative behavior,and the research has the following shortcomings:?1?It only focuses on the cooperative behavior of one person in the cooperative task,but lacks the real interaction research between the cooperative parties;?2?the brain mech anism of perceived social mindfulness on cooperative behavior is lack.Therefore,This st udy used cooperative games and combined with fNIRS hyperscanning technology to e xplore the effects of perceived social mindfulness on cooperative performance and the underlying brain mechanisms.The mixed experiment design of 2 Perceived social mindfulness?condition:high a nd low?×2 Task type?task:cooperative task and competitive task?was adopted.A total of 52 female college students were randomly divided into 13 pairs of high and low perceived social mindfulness.The adapted object selection game and cooperative game were combined with fNIRS superscan technology to simultaneously record the brain activity of the right prefrontal cortex?rPFC?and right temporoparietal joint area?rTPJ?of the two subjects.The mean response time,the difference of response time,t he average cooperation rate,the change value of cooperation rate and the index of in terpersonal neural synchronization?INS?were analyzed.?1?Retrospective questionnaire results:There are significant differences in the five variables of Willingness to Collaborate,Desire to Meet in real life,Liking,Perceived Se lf Interestedness,and Perceived Social Mindfulness for the high-and low-perceived s ocial mindfulness.?2?Behavioral results of cooperative games:Compared with competi tive tasks,the average response time of cooperative tasks is larger;compared with lo w-perceived social mindfulness,the difference in response time of high-perceived socia l mindfulness is smaller.?3?fNIRS results:In the cooperative task,compared with the low-perceived social mindfulness,the high-perceived social mindfulness had a higher average cooperation rate,and the intertemporal coherence of the right temporal parietal joint area was significantly enhanced.The Anatomical position is the right central ant erior gyrus?channel 16?,right top upper gyrus?channel 17?,and right central posterio r gyrus?channel 19?;In competitive tasks,the index of interpersonal neural synchron ization is not Significant differences.?4?Correlation analysis results:In the cooperative task,there is a positive correlation between Coherence Increase and the difference in response time.Conclusion:In the adapted item selection game,the manipulation of high-and lo w-perceived social mindfulness is effective.Perceived social mindfulness can promote cooperative behavior,and high-perceived social mindfulness perform better than low-p erceived social mindfulness.Cooperative tasks involve more complex psychological con tent and take longer than competitive tasks.In cooperative tasks,subjects with high-pe rceived social mindfulness activated in the right temporal parietal joint area?right cent ral anterior gyrus,right parietal superior gyrus,and right central posterior gyrus?and activated at a neural level.The modulation of interpersonal neural synchronization by perceived social mindfulness improved the cooperation performance of the participants.In the cooperative task,the two subjects were not only closely linked at the behavio ral level,but also enhanced in interpersonal neural synchronization.
