Abstract

Ethnic dance serves not only as a form of artistic expression but also as a psychological mechanism that cultivates group identity, social cohesion, and emotional regulation. This study investigates the role of Bai ethnic dance in Yunnan Province as a psychosocial tool that strengthens collective emotional experiences and interpersonal trust. Adopting a qualitative case study approach, the research examines Bai dance performances—specifically those held during the Raosanling Festival and Deng Ga Gan Zhou—focusing on their function in activating psychological processes such as emotional contagion, cognitive reinforcement, and synchronised movement. The study employs secondary data, archival research, and thematic analysis to explore how Bai dance reinforces community bonds and emotional resilience. The findings reveal that Bai ethnic dance promotes social cohesion through synchronised movement and collective participation, thereby enhancing psychological resilience and group attachment. The dance fosters emotional bonding, reduces social isolation, and encourages intergenerational interaction, thereby maintaining community unity. In contrast to many cultural performances that have been adapted for commercial purposes, Bai dance retains its psychological significance as a mechanism for social connection and emotional regulation. This study makes a valuable contribution to cultural psychology and social behaviour research, offering insights for policy, education, and community initiatives that leverage traditional dance to promote social integration and psychological well-being.
