Evaluation Concerns and the Köhler Effect

This study examined whether increasing evaluation concerns would increase the magnitude of the Köhler effect (i.e., one type of motivation gain that has been documented to occur in small groups). Evaluation concerns were manipulated by having participants work in the physical presence or virtual presence of their coworker. As anticipated, motivation gains were significantly greater for participants who worked in the physical presence of their coworker. These results suggest that evaluation concerns can potentially increase the magnitude of the Köhler effect. Furthermore, the findings have implications for practitioners and researchers interested in the differential impact that face-to-face and virtual mediums have on motivation in groups or teams.
