Group Identification, Intergroup Perceptions and Collective Action

This chapter examines the impact of group identification on intergroup perceptions and on willingness to take part in collective action. Based on social identity theory, the argument is put forward that strong group identification is associated with intergroup differentiation and stereotypic perception. This in turn has implications for the acceptance of social influence from ingroup and outgroup sources. In addition, group identification facilitates participation in collective action by promoting shared perceptions within the ingroup concerning the desirability and possibility of social change. Participation in collective action feeds back to affect the individual's attitudes and social identity.
