The special issue of the American Psychologist (May-June 2018) is devoted to the science of teamwork, with 20 articles addressing the history and foundation of teamwork research and highlighting the importance of teamwork in aviation, military, business, space exploration, academic, and health care settings. Articles that address factors influencing team performance and evaluation of interventions with teams are also included. The editors of the special issue direct attention to key areas in teamwork research that would benefit from further inquiry. That is, a call is made for research that focuses on teamwork measurement and assessment tools, explores multi-team systems, and bridges the gap between theory and practice. The special issue is a gem, likely to advance teamwork research in the years to come. Missing, however, is discussion of research related to sport teams and the sport psychology literature, although a sport team is featured on the cover of the science of teamwork special issue.
