Research has demonstrated that task performance of low self-esteem individuals (low SEs) suffers in the presence of self-focusing stimuli (e.g., a mirror). The present study determined if such stimuli must inevitably have adverse effects on low SEs. It was reasoned that if low SEs were provided with success feedback from a previous task, then the nature of their self-consciousness would be altered on a subsequent task. Specifically, low SEs should attend more to positive and less anxiety-provoking aspects of themselves than would low SEs who received failure feedback from the previous task. Under the former condition, low SEs' subsequent task performance was expected to improve. For high SEs, who typically perform well, success-failure feedback was expected to have little effect on subsequent performance. 90 undergraduates high and low in chronic self-esteem received false success or failure feedback from a task and completed a concept formation task in either the presence or absence of a mirror. Whereas high SEs performed equally well following success or failure, low SEs in the success condition performed significantly better than low SEs in the failure condition. This Self-Esteem × Prior Feedback interaction was significant in the presence of the mirror but not its absence.
