It has been suggested that a positive mood enhances creative performance. However, there is insufficient research considering individual differences in creativity. The purpose of this study was to clarify the relationship between the influence of mood on task performance and individual differences in creativity. In the experiment, participants were asked to complete the Alternative Uses Task after evaluating their impression of wall colors and induced mood. We analyzed the relationship between a positive mood’s influence on task performance and individual differences in creativity, and found that individuals with a high correlation between positive mood and creativity were significantly more original than others. These results suggested that the influence of mood on creativity relates to height of creativity.
