“The whole is greater than the sum of its parts” – Ideally this statement is true when we work in teams. However, as probably most of us know from experience, team cooperation does not happen naturally. Instead, teams sometimes have destructive meeting dynamics or face challenges related to leadership, diversity, timing, and performance. Our research focuses on gathering insights into the positive and negative aspects of team work and providing evidence-based management strategies to tackle the potential problems of team cooperation in work teams, (senior) management teams and supervisory boards. We study from a psychological perspective a range of temporal team processes such as interaction patterns, the creation of shared mindsets, or emergent affective states. We seek to generate rigorous insights that are relevant both for research and for practice to ultimately help teams, at all levels of the organization, to become more effective.
