It is often accompanied by fear of negative evaluation and instable self-esteem. This study used a SELF- speech task and looked at the discrepancy trait of perfectionism specifically to examine how individuals with this trait update their feelings about the self, with the expectation that they would show a negativity bias. Additionally, it was hypothesized that these individuals would show differences in brain activity (mid-frontal theta oscillations) caused by negative feedback. Ninety-five participants, out of which fifty-two were in the high discrepancy group, gave a speech about themselves and received positive and negative feedback about their performance. Results of this study show that individuals learn differently from negative and positive feedback. More specifically, both groups showed a positivity bias indicating that they update their feelings about the self more after receiving positive than negative feedback. Differently than expected, the high discrepancy group did not show negativity bias and had learning rates similar to the low discrepancy group. This study also found that theta power activity was not correlated to the mismatch or valence of the feedback received after the task. Furthermore, no group differences in theta power activity were found. These findings indicate that the discrepancy between one’s expectations and self-perception is not related to a negativity bias or increased mid-frontal theta power oscillations. Future research should focus on other classifications of perfectionism to confirm these findings.Show less
