ABSTRACT
Computer-mediated small group research has focused efforts on the medium of electronically networked text-based messages. An experiment which instead combines a synchronous text-based messaging medium with two-dimensional interactive computer graphics is detailed. Three-person groups participated in a risk-taking choice-dilemma task involving a discussion of the dilemma and consensus attainment. The groups' prediscussion and postdiscussion opinions were collected. Two conditions, one where groups received graphics-based feedback of their individual prediscussion opinions, and a second, which included a graphical representation of the prediscussion average, were coupled with a text-based communication medium. The text-based medium, without interactive graphics, served as control. In the condition involving the graphical prediscussion opinions and average, groups sent proportionately more messages containing persuasive-style arguments and proportionately fewer messages containing normative-style arguments. In the graphical condition without the average, roughly the inverse was found to occur. In the control, the discussion parameters fell proportionately between the two graphics conditions. In both graphics conditions, the first discussant to advocate a decision proposal had a stronger influence on the group decision than in the control. The data suggests that the inclusion of two-dimensional graphics can either augment or inhibit normative and informational forms of social influence during the group decision-making process.
