“…Research into shared mental models is based on the proposition that if team members share similar mental models of the abilities, skills, and processes of the group, they will be able to communicate and coordinate with one another more effectively and, ultimately, perform better (BarTal, 1990; Cannon-Bowers, Salas, & Converse, 1993;Salas, Dickinson, Converse, & Tannenbaum, 1992). The empirical research not only supports this proposition (Argote, 1989;Marks, Zaccaro, & Mathieu, 2000;Mathieu, Goodwin, Heffner, Salas, & Cannon-Bowers, 2000;Peterson, Mitchell, Thompson, & Burr, 2000;Walsh, Henderson, & Deighton, 1988) but suggests that other forms of homogeneity also are beneficial for group performance and well-being. For example, homogeneity in attitudes and affect has been found to be associated with lower group conflict, higher member satisfaction, and more prosocial behavior (Barsade, Ward, Turner, & Sonnenfeld, 2000;Krebs, 1975).…”
