Movement Synchrony Influences Intergroup Relations in a Minimal Groups Paradigm

Studies show that synchronizing movements with others encourages a collective social identity, leading to increased cooperation within a group. The current study investigated whether movement synchrony impacts social categorization and cooperation across intergroup boundaries. Two 3-person groups were brought together under movement synchrony conditions designed to emphasize different social categorizations of the aggregate: all individuals moved to the same beat, each minimal group moved to a different beat, or each individual moved to a different beat. Results demonstrate that movement synchrony influenced social categorization and cooperation across intergroup boundaries. Implications for approaches to intergroup relations using movement synchrony are noted.
