Modulation Of Neural Mechanisms Of Empathy For Social Rejection By Self-other Overlap

As social animals,human beings have the instinctive need of social interaction,love and belonging.Empathy is the tendency to share and understand the feelings of others,and is an essential component of social ability.Everything has a kind of similar emotion,and it has a heart of compassion.It has a certain empathy for the experience of others.Pain empathy is a kind of empathy that is closely related to daily life.It refers to the individual's perception,judgment and emotional response to other Individuals ' pain.With the development of information age,Individuals ' forms of communication and communication environment are also undergoing rapid changes.The frequency of interpersonal communication is more frequent.Individuals growing up in different environments are also colliding with each other.Social exclusion has become a common phenomenon.For individuals,people who tend to empathize people who are close to themselves because they are more similar,with a greater degree of overlap in the neural representation between self and others.When an individual observes rejection by others,how does it react,and how the responses of different subjects are different,it is particularly important to study these issues more extensively and systematically.The present study aimed to investigate how the self-other overlap affected the neural response to empathy for social rejection.We used within-subjects design of two factors.One fact is the degree of self-other overlap.It is divided into three levels,self,friends and strangers.The other factor is the type of stimulation,which is divided into two levels,namely social acceptance and social rejection.The dependent variable is the characteristic wave induced by the rating and reaction time and each condition.We recruited 28 participants and used the self-other overlap scale to measure the overlap between the subjects and their friends,and then used the improved form of the chat room paradigm to simulate the acceptance and rejection scenarios in social interactions.According to the analysis results of the ERP experiment,the main conclusions of this study were as follows:(1)The early stage of social rejection empathy is mainly located in frontal-central region,preferential processing of stimulus types and bottom-up stimulus-driven processing in the early stage of empathy for social rejection,which is manifested by the positive average amplitude of ERP component P2 under the condition of rejection stimulus.(2)When an individual is in a disadvantageous situation to himself,he will pay more attention to himself,and his empathy for social rejection will be weakened.At this time,he will allocate more resources to process rejection stimulus.When he watches his own evaluation feedback,the average amplitude of rejection stimulus is more correct than that of LPP(600-800ms)induced by acceptance.However,when he watches the evaluation feedback of friends and strangers,this kind of response does not occur.(3)When individuals engage in social rejection and empathy for different interpersonal distance objects,they first call the social comparison mechanism and then call the emotion sharing mechanism.The specific performance is as follows:the average volatility of LPP(400-600ms)is very significant when watching feedback from friends,friends and strangers.In LPP(600-800ms),the difference between yourself and friends becomes no longer significant,showing two Different processing modes.The study have shown that empathy for social pain occurs later than physiological pain,empathy for social rejection includes early automated processing and late cognitive control regulation,self-other overlap modulates the late stage of empathy for social rejection.
