Team meetings are affect-laden environments where team members may motivate and energize, or frustrate and agitate each other. The importance of affect in teams generally and in team meetings particularly has led to a growing body of research that focuses on group affect. Existing conceptual and empirical work has contributed to our understanding of the nature of group affect and its implications for critical organizational phenomena, including emotion convergence and divergence, emotional contagion, emotional norms, and leadership. In this chapter, we review and integrate this literature and suggest directions for future research on affective dynamics during team meetings. We first briefly review contemporary research that has used a compositional approach to group affect. We highlight the need for a dynamic approach to group affect and call for more research in this area. We assess what has been learned and discuss suggestions for future theoretical development and methodological approaches for meetings researchers invested in this important interpersonal, dynamic construct.
