In this article, the authors seek to augment Dean Hewes's (1986, 1996) intriguing bracketing and admirable larger effort to "return to basic theorizing in the study of group communication" by making transparent the foundational, and debatable, assumptions that underlie those models. Although these assumptions are addressed indirectly by Hewes, the…

This article presents the authors' response to Hewes's (1986, 1996, 2009) models of communication effects on small group outcomes. As sophisticated and thoughtful as Hewes's new model is, however, the authors take issue with it. For one, there is reason to question whether his approach is feasible. For another, his models are not founded on solid…

This article presents the author's response to Professor Hewes's "The Influence of Communication Processes on Group Outcomes: Antithesis and Thesis." The author believes that Hewes could have been more helpful to the reader and to those who are apt to find inspiration in the steps he has taken in his essay to promote a "return to basic theorizing…

The purpose of the author's contribution to this colloquy was to spark conversation on the theoretical nature of communication processes and the evidentiary requirements for testing their relationship to group outcomes. Co-discussants have raised important issues concerning the philosophical basis of the socioegocentric model (SM) and dual-level…

An experiment tested hypotheses derived from self-categorization theory's explanation for gender-based language use. Under high or low conditions of gender salience, men and women sent e-mail to an ostensible male or female recipient yielding either an intra- or an intergroup setting. Gender salience was manipulated so that the stereotypically…

Discusses three studies stemming from an investigation designed to demonstrate that group decision-making performance is contingent on the satisfaction of four functional requirements. Claims the studies provide further support for the functional perspective. (JAD)

Seeks empirical data on whether communication is an essential element of effective decision making and whether the variance in group decision making is best accounted for by noninteraction or interaction sources. Shows that group communication is related to group performance independent of the influence of noncommunication factors like group…

Proposes interaction hypotheses involving the social, interpersonal, and intellectual responses of group members collaborating via computer-mediated communication. Finds that some conditions of computer-mediated communication used by geographically dispersed partners rendered effects systematically superior to those obtained in other mediated…

Assesses Persuasive Arguments Theory (PAT) assumptions about argument and argument influence. Reviews and critiques PAT, advancing five hypotheses to test its assumptions. Finds little correspondence between cognitive and discussion arguments in number, content, or persuasiveness. Discusses implications for PAT and for the role of communication in…

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)

Contrary to previous work in which task-related judgments are hypothesized to predict participation in small groups, the current study assumes that participation is both an outcome of and an influence on judgments of task-related ability. In this study, the association between task-relevant judgments and participation was examined at two points in…

Strongly confirmed the hypothesis that groups employing an interacting decision procedure would produce better decisions than groups employing procedures that are either nominal (Delphi) or "staticized" (individual judgments statistically pooled). Provides clear and consistent support for the value of social interaction in small group…

Explores inconsistent findings in earlier brainstorming research. Indicates that variation in the number of high and low apprehensive communicators assigned to a brainstorming group affects member productivity, perceptions of status differentiation, and satisfaction with the group. Supports the conclusion that communication predispositions and…

Investigates whether a member with information critical for making the best group decision positively influences the group's final choice. Examines impact of status differences among members and of communication media (face-to-face versus computer-mediated communication). Finds that mixed-status groups made poorer decisions and fewer references to…
