In this special issue, we trace the evolution of group cohesion research from the past to the present day. We are reprinting four classic articles on group cohesion that all mark important turning points in the literature, and we conclude with a modern day review of cohesion in the sports context. Together, these articles span the decades of cohesion research, providing interesting insights into how cohesion has been viewed at different points in time, how the field has developed, and how research on group cohesion still can grow.

Past research examining group cohesion and performance was reviewed using metaanalysis. The results indicated a positive relationship with the average cohesive group performing 18 percentile points above the average noncohesive group. Given the nature of the studies used here (all studies had been previously published), caution is suggested in generalizing these results to" real" work groups.
