Productivity loss in brainstorming groups: Toward the solution of a riddle.

Abstract: We conducted four experiments to investigate free riding, evaluation apprehension, and production blocking as explanations of the difference in brainstorming productivity typically observed between real and nominal groups. In Experiment 1, we manipulated assessment expectations in group and individual brainstorming. Although productivity was higher when subjects worked under personal rather than collective assessment instructions, type of session still had a major impact on brainstorming productivity under conditions that eliminated the temptation to free ride. Experiment 2 demonstrated that inducing evaluation apprehension reduced productivity in individual brainstorming. However, the failure to find an interaction between evaluation apprehension and type of session in Experiment 3 raises doubts about evaluation apprehension as a major explanation of the productivity loss in brainstorming groups. Finally, by manipulating blocking directly, we determined in Experiment 4 that production blocking accounted for most of the productivity loss of real brainstorming groups. The processes underlying production blocking are discussed, and a motivational interpretation of blocking is offered. In his influential book, Osborn (1957) suggested brainstorming as a method of group problem solving that considerably increases the quality and quantity of ideas produced by group members. Brainstorming groups are traditionally given instructions designed to free the individual members from the inhibiting effects of self-criticism and the criticism by others during the problem-solving session. The rules behind brainstorming are as follows: keep in mind that the more ideas the better and the wilder the ideas the better, improve or combine ideas already suggested; and do not be critical. Osborn (1957) claimed that if these rules are followed "the average person can think up twice as many ideas when working with a group than when working alone" (p. 229).

Group performance and decision making.

Abstract: 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 decision making research has focused on preference combination for continuous response distributions and group information processing. New approaches (e.g., group-level signal detection) and traditional topics (e.g., groupthink) are discussed. New directions, such as nonlinear dynamic systems, evolutionary adaptation, and technological advances, should keep small group research vigorous well into the future.

Design Thinking for Social Innovation

Abstract: DESIGNERS HAVE TRADIIONALLY FOCUSED ON ENHANCING THE LOOK AND FUNCTIONALITY OF PRODUCTS. RECENTLY, THEY HAVE BEGUN USING DESIGN TOOLS TO TACKLE MORE COMPLEX PROBLEMS, SUCH AS FINDING WAYS TO PROVIDE LOW-COST HEALTH CARE THROUGHOUT THE WORLD. BUSINESSES WERE FIRST TO EMBRACE THIS NEW APPROACH—CALLED DESIGN THINKING—NOW NONPROFITS ARE BEGINNING TO ADOPT IT TOO.

Hedonic tone and activation level in the mood-creativity link: toward a dual pathway to creativity model.

Abstract: To understand when and why mood states influence creativity, the authors developed and tested a dual pathway to creativity model; creative fluency (number of ideas or insights) and originality (novelty) are functions of cognitive flexibility, persistence, or some combination thereof. Invoking work on arousal, psychophysiological processes, and working memory capacity, the authors argue that activating moods (e.g., angry, fearful, happy, elated) lead to more creative fluency and originality than do deactivating moods (e.g., sad, depressed, relaxed, serene). Furthermore, activating moods influence creative fluency and originality because of enhanced cognitive flexibility when tone is positive and because of enhanced persistence when tone is negative. Four studies with different mood manipulations and operationalizations of creativity (e.g., brainstorming, category inclusion tasks, gestalt completion tests) support the model.
