“…Manifest to some degree among all groups is the existence of cohesion. The perceived worth of cohesion as a mediator of group formation, maintenance, and productivity has led it to be considered by some social scientists as the most important of group variables (Bollen & Hoyle, 1990; Golembiewski, 1962; Griffin & Pennscott, 1991; Lott & Lott, 1965). Evidenced by the numerous studies conducted since the 1950s (e.g., Festinger, Schachter, & Back, 1950), cohesion is linked to a range of variables across a variety of disciplines, for example, work group effectiveness and performance barriers in organizational teams (Tesluk & Mathieu, 1999), work peer appraisals (Urch-Druskat & Wolff, 1999), collaboration groups in virtual education programs (Gonzalez, Burke, Santurzzi, & Bradley, 2003), group membership duration (McPherson & Smith-Lovin, 2002), and attitude projection (Holtz, 2004).…”
