Abstract

Researchers have proposed that the contradictions observed between past group support system (GSS) laboratory and field research may be partially accounted for by the ad-hoc nature of the groups that are often used in the laboratory. To examine this, a laboratory experiment examining the influence of group history (i.e., established versus ad-hoc groups) and the level of computer support (i.e., communicating via a computer-mediated system versus face-to-face) was conducted. Dependent variables examined in the research include information-sharing performance, decision quality, and member perceptions. Subjects completed a hidden profile task - a task where some information is held by all group members prior to the meeting, while other information is held only by a subset of the group. As expected, established groups discussed less unique information than ad-hoc groups. In addition, information sharing was positively related to the quality of group decisions. Members of established groups were more satisfie d than members of ad-hoc groups; members using the computer-mediated system were less satisfied than those communicating face-to-face. In addition, group cohesion was positively related to satisfaction and decision quality. The results are discussed in the context of prior theory and research. Opportunities for future research are also described.
