COOPERATIVE VERSUS COMPETITIVE EFFORTS AND PROBLEM-SOLVING

The impacts of cooperative and competitive efforts on problem solving were compared. In order to resolve the controversy over whether cooperation promotes higher- or lower-quality individual problem solving than does competition, 46 studies, published between 1999 and 1993, were examined. The findings from these studies were classified in 4 categories according to the type of problem solving measured: linguistic (solved through written and oral language), nonlinguistic (solved through symbols, math, motor activities, actions), well-defined (having clearly defined operations and solutions), and ill-defined (lacking clear definitions, operations, and solutions). The 63 relevant findings that resulted were subjected to a meta-analysis for purposes of integration. Members of cooperative teams outperformed individuals competing with each other on all 4 types of problem solving (effect sizes = 0.37, 0.72, 0.52, 0.60, respectively). These results held for individuals of all ages and for studies of high, medium, and low quality. The superiority of cooperation, however, was greater on nonlinguistic than on linguistic problems.
