Examines consensus as a function of group members' decision rule orientations. Finds that for groups that interacted verbally, consensus was more likely between groups composed of members with matching (rather than differing) rule orientations. Discusses implications for group consensus and the decision rule orientation construct. (MM)

Builds a typology of the temporal paths by which decisions develop. Develops a typology with 11 different decision paths in three main groups: unitary sequences, complex sequences, and solution-centered sequences. Finds analysis of this typology supports the multiple sequence model, but also suggests a role for normative unitary models. (MS)

Reconceptualizes groupthink symptoms as observable group interaction patterns. Proposes two coding systems for detecting the illusion of unanimity symptom, detecting both degree of unanimity and degree of the illusory versus substantive nature of that unanimity. (SR)

Compares decision processes of consensus and devil's advocacy within an additive task, a disjunctive task, and a conjunctive task structure. Finds that high-conflict decision processes such as devil's advocacy enhances decision making in disjunctive tasks, retards decision making in additive tasks, but has no effect on decision making in…

In the history of small group studies (in the field of communication theory and research), two factors contributed to the changes that led to Ernest Bormann publishing in 1970 his work questioning the value of the knowledge being reported and the appropriateness of the methods by which it was being generated. First, prior to 1965, a limited amount…

Recent social scientific interest in juror selection has advanced the "voir dire" (jury selection) process beyond Clarence Darrow's formula for choosing a jury likely to be sympathetic to his client. From a communication perspective, generalization to different cases in different sections of the country and under different conditions…

Analyzes how a new computer technology, Group Decision Support System (GDSS), affected how group decisions developed over time. Contrasts decision paths in groups using the GDSS with groups using GDSS procedural structures manually and with groups using no procedural structures. Finds that decision paths varied and were related to consensus…

A study examined the effectiveness of an experiential learning exercise in a speech communication classroom setting. Participants were 62 students in communication classrooms in a large southwestern university. The exercise, entitled "The Ace, Incorporated Hanging Tray Company Exercise" was done as a group communication exercise…

To assess whether communication behaviors differ between high and low consensus groups, a study considered the comparative interaction of the first meetings of high and low consensus groups, the first and final meetings of high consensus groups, and the first and final meetings of low consensus groups. Subjects, 84 students in a small group…

An examination of the impact that process instructions have on jury deliberations was conducted using ten juries of six members each. Five of the juries were given standard jury instructions, while the remaining five were given step-by-step instructions in the deliberation process designed especially for that trial. The results indicated that…

A study tested a model of bargaining rite by examining procedural rituals, organized fantasies, and ritualistic language in teachers' negotiations. Specifically, it sought to identify the communicative forms that create shared consciousness, to describe shared fantasies, to illustrate the role of group fantasy in forming rhetorical visions, and to…

The decisions President Richard Nixon and his closest advisors made in the Watergate coverup were products of what Irving Janis calls "groupthink." Groupthink, a type of decision-making emphasizing unanimity over objective evaluation, develops when the decision makers (1) form a group of marked cohesiveness, (2) insulate themselves from…

To provide a theoretical base for investigating the influence of inferential error on group decision making, current literature on both inferential error and decision making is reviewed and applied to the Watergate incident. Although groups tend to make fewer inferential errors because members' inferences are generally not biased in the same…

Findings suggest, among others, that argumentativeness is an important variable in the perception of leadership, with the highly argumentative individual chosen leader over the moderate or mildly argumentative individual. Highly argumentative individuals were also rated as more influential on the group's decision. (PD)

Focuses on personality as a predispositional factor which is predictive of the direction of both persuasive argumentation by group members and, subsequently, decision shifting. Tends to validate the value theory of polarization by showing that persuasive argumentation can mediate the effect of personality on decisional shifting. (PD)
