Conducted among parents of young ice hockey players, this field experiment tested if making salient increasingly popular social norms that promote sportspersonship, learning, and having fun in sports, increases parents’ own self-determined endorsement of these behaviors and values, improves their psychological well-being, and impacts on their children’s on-ice behaviors. Hockey parents were randomly assigned to the experimental condition vs. control condition. Parents’ motivations for encouraging their child to learn and to have fun in hockey were then assessed. Score sheets for (...) the games that followed the study provided access to their children’s on-ice behaviors, as indicators of sportspersonship. Parents in the experimental condition reported higher self-determination for encouraging their child to learn and have fun in hockey compared to parents in the control condition. Furthermore, children of parents in the experimental condition had more assists. A mediation model revealed that the dynamic norms manipulation increased parents’ self-determined motivation for encouraging their child to learn and to have fun in hockey, which in turn, predicted higher psychological well-being. Together, these results provide support for the contention that highlighting increasingly popular social norms that promote sportspersonship, learning, and fun in sports, represents a promising strategy for creating positive social change in this life context.

This article proposes that all psychologists-and all psychologies-are innately concerned with justice, and yet there is no consensually defined discipline of psychology, and no consensual understanding of social justice. Adopting an intergroup and identitybased model of what is and what should be, we will describe the mechanisms whereby identities and perceptions of justice are formed, contested, and changed over time. We will argue that psychological research and practice have implications for social justice even where-and perhaps especially when-these are not made (...) explicit. Psychology is considered as the product of diverse groups with distinct and evolving identities, and with differential access to resources and power, which dynamically contest different normative perceptions of justice.

Whitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.
