Contributions of group identification and emotional synchrony in understanding collective gatherings: A meta-analysis of 13 studies

The present research aims to explore the relationship between group identification and emotional synchronization in a series of collective gatherings and evaluate their respective effects on key social-psychological variables. Thirteen studies were conducted in highly varied contexts, studying naturally happening phenomena, and focusing on a wide range of collective gatherings (N = 2,260 participants). The results of factor analyses and a random-model meta-analysis strongly support the idea that group identification and emotional synchronization constitute two differentiated constructs that are systematically positively associated. At the aggregate level, results of multilevel models show that both group identification and emotional synchronization are significant predictors of key social-psychological variables. These findings suggest that an integrative approach is most needed to capture the experience of collective gatherings.
