One benefit of working in groups is that group members can learn from each other how to perform the task, a phenomenon called group-to-individual transfer (G-I transfer). In the context of quantitative judgments, G-I transfer means that group members improve their individual accuracy as a consequence of exchanging task-relevant information. This…

Collaborative problem solving (CPS) is a 21st-century skill essential for learning gains, workplace success, and tackling increasingly complicated global problems. Group diversity plays a vital role during collaborative activities, especially in a digital space. Although CPS involves dynamic communication behaviors, few studies have considered the…

Engineering ethics education typically focuses on decisions by individual engineers and case studies of disasters. This does not reflect the everyday decisions that practicing engineers must make, and neglects the fact that most engineers work on teams rather than alone. The focus on safety and disaster prevention leaves little time for discussing…

The purpose of this mixed-methods study was to explore students' reactions to a case involving peer rating. We asked undergraduate and graduate students at a Midwestern liberal arts university to rate the performance of a close friend. To explore how role might impact the students' decisions, we randomly assigned participants to one of two rating…

The use of data for educational decision making has never been more prevalent. However, teachers and school leaders need support in data use. Support can be provided by means of professional development in the form of "data teams". This study followed the functioning of 4 data teams over a period of 2 years, applying a qualitative case…

Group decision making should be particularly beneficial when group members share unique information, because then a group can make a better decision than each group member alone. This study examined how elementary-school children share unique information during group decision making. Seventy-nine groups of 3 same-sex and same-age 7- and 9-year-old…

Analyzed group discussions associated with 68 high-quality and 29 low-quality decisions made by comparably informed groups using cross-contact comparison. Found vigilance, second-guessing, and accurate information processing associated with high-quality decisions; faulty information processing and improbable fantasy chains with low-quality…

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…

Goldstein and Gigerenzer (2002) [Models of ecological rationality: The recognition heuristic. "Psychological Review," 109 (1), 75-90] found evidence for the use of the recognition heuristic. For example, if an individual recognizes only one of two cities, they tend to infer that the recognized city has a larger population. A prediction…

A study investigated whether the interaction patterns of high consensus groups differed significantly from the patterns of low consensus groups in the final stage of a decision-making task. Eighty-four college students placed into 19 groups were told to select a social problem, investigate it, and develop a solution. At the end of the three-week…

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…

Based on existing theory and research on cooperation and competition and on process studies of group decision making, a two-part study was conducted on the communication patterns in four groups of college students. In the first part of the study groups one and three were induced to behave competitively and groups two and four were induced to…

Comparisons were made of attitudes and behavior between single- and multiperson teams in business simulation games. Multiperson games gave rise to higher initial goals for business success, but lower individual feelings of responsibility for outcome. (CMV)

A study explored the relationship between creative problem solving and group decision making techniques as measured by the outcome variables identified in earlier studies. Subjects, 46 undergraduate students enrolled in communication courses at 2 midwestern universities, were divided into 3 groups, a Nominal Group Technique (NGT), Unstructured…
