Abstract
ABSTRACT: The hypothesis that the effects of positive and negative mood on creative problem solving may differ as a consequence of the degree of constraint on the solution space of the task was tested. Sixty-eight participants were divided into positive mood, negative mood, and control conditions. Mood was experimentally induced by showing selected film clips, and performance on four different idea production tasks was recorded across a time interval of 4 min for each task. Results showed a significant mood-production time interaction. Positive mood led to the highest number of scores in early idea production and the lowest number in late production, whereas both control and negative mood led to relatively superior task performance in late production. Alternative interpretations of the results are discussed, and suggestions for further studies are offered.
