Mood and the quantity and quality of ideas

Two positions concerning positive mood and its relation to creative problem solving have been taken. The general position (GP) postulates that there is a consistent positive relation between positive mood and creative problem solving. The qualified position (QP) states that the relation is a contingent one. This study explores one possible limitation to the GP, by testing Weisberg's (1994) suggestion that positive mood facilitates productivity but not quality of ideas. Self-reported mood was measured by positive, negative, and arousal scales. Divergent thinking tasks scored for fluency, flexibility, originality, and usefulness were used as criterion variables. A perfect theoretically predicted rank order between positive mood and degree of solution constraint measured by the divergent thinking indices emerged. Positive mood was significantly related to an idea quantity factor but not to an idea quality factor. Although this evidence is not conclusive, it supports the QP and indicates that the GP should be modified to include task type and degree of solution constraint.
