Empirical studies on the relationship between affect and creativity often produce conflicting results. This inconsistency has led us to believe that the relationship between affect and creativity may be better understood by looking at potential moderators. Our study looked specifically at trait affect and self-perceived creativity. Using the Affect Infusion Model (AIM) theory with problem clarity as the potential moderator, we hypothesized that when individuals are faced with problems that lack clarity, trait affect has greater sway over their self-perceived creativity. Our results provided evidence that problem clarity moderated the relationship between positive trait affect and self-perceived creativity; the positive relationship between positive trait affect and self-perceived creativity is stronger when problem clarity is low and weaker when problem clarity is high. No moderating effect was found in the relationship between negative trait affect and self-perceived creativity.
