Group performance and decision making.

  title={Group performance and decision making.},
  author={Norbert L. Kerr and Robert Scott Tindale},
  journal={Annual review of psychology},
Theory and research on small group performance and decision making is reviewed. Recent trends in group performance research have found that process gains as well as losses are possible, and both are frequently explained by situational and procedural contexts that differentially affect motivation and resource coordination. Research has continued on classic topics (e.g., brainstorming, group goal setting, stress, and group performance) and relatively new areas (e.g., collective induction). Group… 

The effects of scale and information distribution on group decision-making processes and outcomes

This dissertation bridges two research streams in the group decision making research: the weighted opinion research stream and social decision scheme research stream. In two experiments, the scale of

Motivated Information Processing in Group Judgment and Decision Making

The MIP-G model integrates the influence of many individual and situational differences and combines insight on human thinking with group-level interaction process and decision making and drives the kind of information group members attend to, encode, and retrieve.

Group decision-making from an evolutionary/adaptationist perspective

Over the 20 years that Group Processes & Intergroup Relations has been in existence, evolutionary theory has begun to play a larger role in our understanding of human social behavior. Theory and

Promoting good decisions: How regulatory focus affects group information processing and decision-making

Decision-making groups often fail to exploit their full potential because they do not integrate all relevant information. We propose to address this issue by interpreting group information processing

The Adaptive Use of Recognition in Group Decision Making

Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance and possible mechanisms underlying the adaptive use of recognition in group decision making are discussed.

Making better decisions in groups

The advantages of group decision-making in overcoming biases and searching the hypothesis space for good models of the world and good solutions to problems are highlighted and means of managing pitfalls are discussed.

The effects of mental model formation on group decision making: An agent-based simulation

We investigated dynamics of group decision making on complex problems when agents can form mental models of others from discussion history. Results indicated that as the agents' memory capacity

Hierarchies and decision-making in groups: Experimental evidence

In this study, I investigate differences in decision-making outcomes for groups under different hierarchies using an experimental approach. Many decisions in firms, households, and other contexts are

Group Decision-Making on an Optimal Stopping Problem

Key findings are that people do not often revise their decisions, but, in the consensus and leadership conditions, are more conservative in their initial decisions, allowing the groups to perform better than their individual members.



The Rank-Order Effect in Group Decision Making

Abstract Many studies indicate that group discussion candisproportionately reflect information known by all group members,at the expense of information known to only one group member, andthis is

Signal-detection analysis of group decision making.

Signal-detection theory is used to model the behavior of groups of human participants in a visual detection task and its specification allows specification of performance efficiency, which is a measure of how closely a group's performance matches the statistically optimal group.

Framing and Group Decision-Making: Do Cognitive Changes Parallel Preference Changes?

Abstract Subjects had their initial frames of reference concerning a decision problem (Asian Disease problem; Tversky & Kahneman, 1981, Science,211, 453–458) manipulated in order to compose

Individual Versus Group Decision Making: Social Comparison in Goals for Individual Task Performance

This experiment compares the decisions of individuals and groups on goals for the performance expected from individuals on a problem-solving or an error-checking task. For both tasks, two versions

Information Sampling in Decision-Making Groups

This study examined the impact of members 'task-relevant status (i.e., prior task experience) on the bias in decision-making groups to discuss more common (shared) than unique (unshared) information.

Group decision and social interaction: A theory of social decision schemes.

This paper proposes a general theory (social decision scheme theory) for many kinds of group decision making and illustrates some special case models with a variety of data from several experimental

Group Decision Making with Responses of a Quantitative Nature: The Theory of Social Decision Schemes for Quantities.

This paper extends and adapts the theory of social decision schemes to apply it to group decisions of a quantitative nature and proposes that the group decision processes related to quantities involve compromise and are characteristically different from the consensus processes for discrete choices.

Teams in organizations: recent research on performance and effectiveness.

This review examines recent research on groups and teams, giving special emphasis to research investigating factors that influence the effectiveness of teams at work in organizations, including group composition, cohesiveness, and motivation.

Recognition of Expertise in Decision-Making Groups

Two studies examined the effects of group size and participation requirements on group performance, expertise, and recognition of group expertise. In Study 1, 324 college students were assigned to
