“…One explanation refer to the different perceptions of the group members: Webster & Wong (2008) found that local members of teams report different perceptions of local and remote members -More positive perceptions of their local than their remote members; Pissarra & Jesuino (2005) claimed that anonymity generated more satisfaction among the group members; Staples & Webster (2007) suggested that differential outcomes for traditional and technology-supported virtual teams evolve from selfefficacy differences; Another explanation refer to the different setting of the computer-mediated groups, such as frequency and distance (Cramton & Webber, 1999), lack of feedback and information about team processes (Geister, Konradt & Hertel, 2006), the difficulty in sharing information (Thompson & Coovert, 2003) and the distance communication tools as a limiting technology (Straus & McGrath, 1994). In terms of group outcome measures, researchers consent that groups using face-to-face channel outperform groups using computer mediated communication (Barkhi, Jacob & Pirkul, 1999, Denton, 2006Potter & Balthazard, 2002).…”
