Mosier, Donna J., Dubrovsky, Vitaly J. and Clapper, Danial L. (1995): Effects of Network Pattern and Status Congruence on Computer-Mediated Group Decision Making. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 834-838.

“Classic experimental studies on restrictive communication networks concluded that network patterns and status congruency affect efficiency, satisfaction, and leadership of group decision making. This experiment had a two-fold purpose: (1) to determine if computer-mediated communication would effect the results of these studies; and (2) to assess centrality of network position as a context cue of social status. The results suggested that network pattern retained its influence in computer-mediated groups, while influence of status congruence was weakened by the equalization effects of the computer media. The results also indicated that a center position in the computer network did serve a social-context cue of status: a high-status person exerted status influence only occupying the hub position. Thus, assignment of group members to network positions of equal or different centrality can be used as means of controlling influence of status and authority in computer-mediated groups.”

Dubrovsky, Vitaly J., Kiesler, Sara and Sethna, Beheruz N. (1991): The Equalization Phenomenon: Status Effects in Computer-Mediated and Face-to-Face Decision-Making Groups. In Human-Computer Interaction, 6 (2) pp. 119-146.

“New computer-based communications technologies make possible new or expanded forms of group work. Although earlier researchers suggest that scant social information in these technologies might cause status equalization in groups, no experimental test of this phenomenon has been made. In a laboratory experiment, we compared face-to-face communication with electronic mail in decision-making groups whose members differed in social status. We examined status in two ways: by varying the external status of group members, and by varying the decision task to manipulate expertise. When the groups made decisions in face-to-face meetings, the high-status member dominated discussions with the three low-status members. Also, the high-status member more often was a "first advocate" in the face-to-face discussions, and first advocates were more influential than advocates. These status inequalities in face-to-face decision making were pronounced just when the high-status member's expertise was relevant to the decision task. When the same groups made comparable decisions using electronic mail, status and expertise inequalities in participation were reduced. A striking and unexpected result was that "first" advocacy was shared by high- and low-status members in discussions using electronic mail. This behavior resulted in increased equality of influence across status and expertise. We discuss the implications of these results for research and for design of new communication technologies.”

Dubrovsky, Vitaly J. (1987): Social Exchange in Group Consensus Development: Face-to-Face versus Electronic Mail. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 701-705.

“A sequence of experimental studies (Kiesler et al., 1984; Siegel et al., 1986) revealed that computer media had an unexpected inflammatory effect on group discussions. E.g., in comparison with face-to-face, computer-mediated groups exhibited more uninhibited verbal behavior (such as swearing and name calling). In this study we attempted theoretical explanation of each case of uninhibition encountered in content analysis of group discussion obtained during a recently conducted experiment. The social exchange model (Dubrovsky, 1986) was used for this purpose. The model was empirically specified for group consensus development by means of a special questionnaire. Its predictions were then tested against available experimental group discussions material. This study offers theoretical explanation to most of the observed cases of uninhibited verbal behavior in computer-mediated discussions. It contributes to our understanding of a group consensus development process. It increases the validity of the social exchange model.”
