| The floating children in our country have become a huge group which can not be ignored.The social identity of migrant children is an important indicator to predict the social behavior of migrant children and the relationship between urban population.As an important social interaction,cooperation is an important part of the development of individual society.In order to explore the status of social identity of migrant children and its relationship with cooperative behavior,this paper plans to study from the following three aspects.Study on the selection of Lei Peng self compiled the 2012 "social identity questionnaire for migrant children" and Liu Xin 2013 compiled "migrant children in city social identity questionnaire",4-8 grade 3 schools with 692 students in Shanghai as the research object(406 boys and 286 girls),discusses the current situation of social mobility children’s identity.The results showed that:(1)in migrant children identity evaluation,value recognition,emotion and behaviors,the main effect of grade was significant,there are obvious differences in gender;migrant children recognized the value of significant differences;the interaction of migrant children in grade and gender identity to the.(2)the educational level of parents has an impact on the social identity of migrant children,that is,the higher the level of education,the higher the level of social identity of migrant children.In the study two,we used the classic experimental paradigm to simulate the investment experiment,and examines the difference between children’s identity and cooperation behavior of the ingroup outgroup through the inter subject design.The results are as follows:(1)the higher the level of social identity,the level of identity and the level of behavioral convergence,the higher the level of cooperation.(2)there is no significant difference in the level of cooperation between migrant children and the internal and external groups.In the study three,362 students in grade 4-8 were selected as the subjects(male and female,with a total of 141 students),and the scale of trust was compiled by Alberto Voci and translated by Liu Hua in 2008.At the same time,the relationship between the level of social identity,inter group trust and cooperative behavior is explored by using the classical experimental paradigm,which is a simulation experiment.The results are as follows:(1)Identity evaluation,identity adaptation and behavior convergence arepositively related to intergroup trust.(2)there is a significant positive correlation between cooperative behavior and intergroup trust(3)intergroup trust plays an intermediary role between social identity and cooperative behavior. |
