Nowadays,the individual development of mobile children is getting more and more attention,and the most important one is the psychological development of mobile children.Children who move from rural areas to cities will face many challenges in life and academic life.This study argues that social exclusion will affect the flow of children’s prosocial behavior,and just world belief as part of the individual belief system,and plays a role of intermediary regulation between the two.This paper USES the questionnaire method to investigate the social exclusion,pro-social behavior and the belief of the world in mobile children.Compared with non-mobile children,the social rejection of mobile children is significantly higher.The level of pro-social behavior of mobile children is significantly lower than that of non-mobile children,in both anonymous and altruistic terms.There was a significant difference in pro-social behavior among mobile children of different genders,and women were higher than men in all projects.The level of impartiality of children in mobile children is significantly lower than that of non-mobile children,in terms of social justice and peer justice.On the gender dimension,men scored higher than women in all dimensions except natural justice.Social exclusion is closely related to pro-social behavior and just world belief.The belief of the fair world is a mediating variable in social exclusion and pro-social behavior.Conclusion: the results show that social exclusion affects the pro-social behavior of mobile children,and the impartiality of world belief plays an intermediary role.Therefore,to improve the pro-social behavior of mobile children,it is necessary to reduce their perceived social exclusion and help it establish a stable and high level of just world belief. |
