Avalanche studies have undergone a transition in recent years. Early research focused mainly on environmental factors. More recently, attention has turned to human factors in decision making, such as behavioural and cognitive biases. This article adds a "social" component to this human turn in avalanche studies. It identifies lessons for…

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…

Two organizational problem situations were worked on by 61 teams in 4 conditions: (1) controls, (2) traditional process (goal clarity, commitment, decision making), (3) team learning (assumption surfacing, dialog, reflection), and (4) combined 2 and 3. Team learning produced significantly more double-loop learning. Controls achieved more…

Identifies six major factors that exerted influence on the decision-making process that led to the launch of the space shuttle, Challenger, on January 28, 1986. Concludes that decision to launch Challenger resulted from complex interplay among a number of cognitive, psychological, and social forces constituting the decision environment. (Author/NB)

We examined need for cognition, social desirability, and communication apprehension for their influence on the mention and repetition of shared and unshared information in 8-person decision-making groups. Both need for cognition and social desirability influenced the discussion of shared and unshared information in decision-making groups. The…

This study examines the impact of one important task characteristic for the process by which groups solve problems. The principal comparison is between a generative problem and a choice task, and whether or not the differences between these types of tasks affect the group's methods for arriving at a decision. Two types of analysis are conducted of…

Subjects responded to risk and caution life-dilemma problems in either a group discussion or a control procedure. Before and after experimental treatment, subjects filled in a questionnaire involving whether or not the character in the dilemma should take the risk. Results are discussed. (Author)

Two studies examined certain discrepancies which have been considered important evidence in support of interpersonal comparison (value-adherence) explanations of group induced shifts in choice. (Editor)

Satisfaction is a construct that is important to the development of intrinsic motivation and the continuing effort to learn. Research that helps to identify those factors that contribute to satisfaction is useful in the design of electronic support systems for individuals and groups. This paper investigates the impact of "need for…

The concept of complexity in decision-making can be found in several lines of conceptualization in the area of national and international decision-making. One derives from the classic works on authoritarianism and dogmatism (Adorno, et al., 1950; Rokeach, 1960). Another approach relies on the variables that pertain to group dynamics and to…

Mock juries of six females each listened to a tape-recording of facts in a courtroom trial. Twelve juries heard guilt-appearing facts, and twelve heard innocent-appearing facts. In half the juries hearing each type of trial, jurors heard the facts in the same (Homogeneous) order; in the remaining juries, each of the six jurors heard the facts in a…

Mathematical models have been used extensively to describe the judgmental processes and strategies of individual decision makers, but rarely have the procedures been extended to describe the judgmental strategies of decision-making groups. The present study attempts to extend the procedures for the purposes of describing group decision-making…
