The international research on teams, which is inspired by the input-process-output model, is mostly empirical. Researchers in this field look for causal explanations between independent (e.g., team size and team composition) and dependent (e.g., team performance) variables. Recently, some critics have pointed to the deficits in this model. Especially, the temporal, contextual, and dynamic aspects of teams need to be investigated further (multilevel approach). Emergent states, such as team cognitions, team emotions, and team hierarchies, comprise a promising field of study that leads to a more comprehensive and holistic understanding of teams. These emergent states offer an opportunity to reconcile former concepts (Lewin’s gestalt, Koestler’s holarchy, and Cattell’s syntality) with topical team research. Therefore, the future of research on teams may partly lie in its past.
