Psychology has long been interested in both intergroup and intragroup contacts, and how such inevitable liaisons can lead to cooperation or conflict. However, despite the proliferation of research on intergroup dynamics in psychology, intragroup dynamics remain relatively undertheorized, especially in the context of Indigenous diaspora communities who maintain ties with both newly settled communities as well as their homelands. Reviewing findings from a qualitative study on Indigenous decolonial activism in Guåhan, this presentation will explore the value of an intragroup perspective to understand the complex negotiations of identity, place, and belonging in diasporic Indigenous CHamoru activists. Discussion will examine how unique experiences of Indigenous diaspora groups have the potential to expand our understanding of intragroup and acculturation processes, with implications for strategies to promote group cohesion and transnational Indigenous identity.
