This study investigates cultural and communication medium effects on conversational argumentation in a decision-making context. Chinese and U.S. participants worked in pairs on two decision-making tasks via face-to-face (FtF) and instant messaging (IM). The analyses showed that Chinese participants tended to engage in potentially more complex…

Builds on previous research with this detailed analysis of multiple decision sequences in two sets of groups: students performing a ranking task and physicians performing a program planning task. Finds support for the Multiple Sequence Descriptive System and isolates types of conflict and idea development patterns. (PD)

Suggests that usurpation of control by a leader causes low-status group members to become dissatisfied with participation, but perceived lack of support causes dissatisfaction with the level of goal attainment. Tables and bibliography. (RW)

Found no single sequence of interaction phases that led to successful or unsuccessful group problem solving. Successful groups, however, tended to begin their discussions by attempting to analyze the problem before searching for solutions; unsuccessful groups immediately began searching for solutions. (PD)

Investigated how majority and minority arguments are positively or negatively responded to by group members and the effects of such responses on the polarization process. Demonstrated that reactions to minority arguments, not the forwarding of minority arguments per se, were significantly correlated with the degree of group polarization. (PD)

Supports the hypothesis that interaction processes connected with the Valence Distribution Model mediated the effect of decision schemes on group decisions. Substantiates the assumptions that interaction is a crucial factor in group decision making. Although input conditions may also have an impact on decision outcomes, they are mediated by…

Found that the discussions of "effective" and "ineffective" groups were distinguished by (1) how the groups examined opinions and assumptions advanced by group members; (2) how the groups evaluated alternative choices; (3) the nature of decisional premises; and (4) the nature of influence exerted by influential members of the group. (PD)

Offers support for the idea that dissonance is aroused only if the consequences of a discrepant action are known in advance and responsibility freely assumed. Graphs, tables, and bibliography. (RW)

Senior level psychology majors and inservice counselors were administered the Rehabilitation Counseling Judgment Scale. A comparison of individual decisions, after sharing their thoughts in group discussion, indicated that group decisions were riskier than individual decisions. Implications of the effects of group interaction on rehabilitation…

Examined the skill and gender of individual group discussants and the sex composition of the group as factors potentially influencing perceptions of emergent leadership. Confirmed that task competence, more than gender, was crucially related to an individual's emergence as the group's leader. (PD)

Studies the sequence of phases in group decision making. Compares the unitary sequence model, which assumes that all groups follow the same sequence of phases, and the multiple sequence model, which assumes that different groups follow different sequences. Results support the latter model and suggest revisions in current decision development. (PD)

After 24 triads of college students discussed hypothetical situations of serious and moderately serious acts of plagiarism by either high or low status individuals, they designated a punishment. The hypothesis was that the severity of the sanction would be a joint function of the severity of the act, the attribution of responsibility for the act,…
