Abstract: | Collective action is one of the core mechanisms of social change, and thus of major importance to social scientists, practitioners, and policy-makers. Our goal in editing this issue is to bring together recent advances on the social and psychological dynamics of collective action among members of disadvantaged as well as advantaged groups. This article introduces the contributions to this issue after a brief review of the major psychological perspectives on collective action (social identity, relative deprivation, and resource mobilization theories), and a discussion of the considerable diversity in collective action research in terms of contexts, populations, and measures. We hope that this issue contributes to a more multi-faceted and integrative understanding of the social and psychological dynamics of collective action in terms of theory, research, policy, and practice. |
