The present study investigated the influence of self-threat on creativity on the one hand and the (creative) self-concept on the other hand. Self-threat leads to self-protection-strategies, which are linked to a decreased cognitive accessibility when dealing with negative self-related information. The decreased accessibility is traced back to an error in information processing called mnemic neglect. Self-threat was supposed to lead to a decreased self-esteem and also to a negative mood, which should further influence the creative performance negatively. After finishing a creativity test 93 participants received either a self-threatening feedback, a self-enhancing feedback, or no feedback to their performance at all. Following the threat manipulation participants performed another creativity test and a list of self-related attributes (creativity and personality items) in terms of how typical the personality traits are for themselves. For the latter task the reaction times were additionally recorded. The results of the study showed, that self-threat had no significant impact on self-esteem, creativity performance and mood. The results acknowledged that people reacted faster to positive items than to negative ones. Mainly after receiving a positive feedback the reaction time to positive creativity items was by trend faster than in the other two feedback conditions. Finally two moderations were detected: After self-threat participants with low trait self-esteem showed slower reaction times on positive personality items than did persons with high trait self-esteem. Also after self-threat people with low trait creativity referred themselve less positive creativity items than did people with high trait creativity. These results lead to the assumption that both trait self-esteem and trait creativity moderate the outcome of feedback.
