Mood and Creativity over Time in a Bipolar Participant

When depression alternates with mania, as in a bipolar affective disorder, creativity might be enhanced. To investigate this, we employed a single-subject design, looking at both affective space and the spectral covariation of mood and creativity in a participant presenting with bipolar affective disorder. The study was conducted over a period of 54 days, and employed a standard measure of mood (the Brief Mood Introspection Scale) and a standard task of creativity (Alternative Uses Task). Both positive affect and negative affect appear to be somewhat undifferentiated for this participant, and her mood space does not conform to that described by the accepted major dimensions of Arousal and Pleasure. Conceivably, this is because of her rapid mood fluctuations. A 2.7-day periodicity was found for Tired, Peppy, Nervous, and Calm, on the one hand, and ideational fluency, ideational flexibility, and originality, on the other. In addition, a 9-day periodicity was common to Happy, Sad, and Gloomy—all three affects clustering in the same affective space—together with both ideational flexibility and originality. This finding brings into question the relationship between creativity and both positive and negative mood.
