Abstract: Social identity threat refers that, in comparison to an out-group, the individual in a particular group failed to identify his/her group status and showed a sense of alienation, deprivation and inferiority. Consequences of social identity threat included three categories: dissociation from the particular group, changing the state of the particular group and reception of the consequences of negative social identity. The explicit measuring of social threat was mainly made up of surveys. Meanwhile, systolic blood pressure and mean arterial pressure were taken as indices in the implicit methods. The experimental research of social identity threat divided the group into inner-group and out-group, manipulated the difference of group status and explored social identity threat and the physical reaction of the group with simulated society game. The following issues will draw great attention in future researches: the conceptual construction of social identity threat, cross-cultural research and analyses of the implicit processes

Key words: social identity threat, social creativity, social competition, group status, antisocial behavior
