However, current research gaps remain regarding the specific factors that may impact the expectancy of negative evaluations in SA. More specifically, age and maladaptive emotional regulation strategies, such as self-blame have yet to be explored as moderators of the relationship between SA and negative expectations of performance. The present study aimed to examine factors contributing to the pessimism bias observed in SA individuals in a probabilistic learning task with a total of 255 male and female participants aged 12 to 29 years. The learning task examined whether participants would learn from the exposure to negative or positive feedback and showcase an increase in their negative or positive expectations respectively. Participants completed a personality questionnaire from which we created a social profile for them. They were shown a set of same-gender peers’ profiles and were asked to indicate the profiles they liked the most to derive their top four. Participants were told their top four choices had also rated their profiles. During the learning task, they were asked to indicate whether they expected to be liked or disliked based on each statement on their profile for each peer specifically. Immediately after each statement rating, they were shown the peers’ actual feedback. The task was set on specific probabilities of giving positive, negative, or neutral feedback to the participants. Participants’ age, self-reported SA levels, and self-blame tendencies were examined as potential contributing factors to increased negative feedback expectancy. Results showed that participants with higher reports of SA illustrated higher negative feedback expectancies across all trials. Overall, across all participants, negative feedback expectancies increased significantly in trials with the most negative peer compared to trials with the most positive peer. Similarly, across all participants, positive feedback expectancies decreased significantly in trials with the most negative peer compared to the most positive peer. Furthermore, adult participants reported higher levels of SA. Results showed that increased SA was a significant predictor of increased self-blame tendencies. Interestingly, self-blame was found to be a significant moderating variable in the relationship between SA and negative feedback expectancies across all trials. These results may be considered promising evidence for alternate future research directions and treatment interventions for the pessimism bias observed in SA individuals.Show less

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

Prior research has shown a link between heart rate changes and social rejection and the possible correlation of self-esteem levels to heart rate changes. Here we examined the effect of positive and negative peer feedback on heart rate changes of participants. Fifty participants (mean age = 20.4) took part in the newly developed social evaluation through feedback (SELF)- paradigm where they predicted, then received social evaluative feedback from four peers who differed in their probability of giving social acceptance versus rejection feedback. We hypothesized that social rejection would result in a transient slowing of heart rate and that this effect would be more prominent with unexpected social rejection. We also expected to find a significant difference in heart rate changes towards each different peer. Moreover, we expected self-esteem to influence heart rate reactions to feedback. As predicted, results revealed a more pronounced deceleration of heart rate during unexpected rejection, though this effect was also found with unexpected social acceptance. Difference in heart rate in response to feedback from each different peers was found, namely a transient slowing of heart rate for negative feedback from Peer 1 and positive feedback from Peer 4. Moreover, levels of self-esteem did not explain a significant amount of variance in heart rate changes. Future research should focus on a larger and more diverse sample size in order to confirm the current findings. This study added to current literature by again confirming a brake in heart rate during unexpected social rejection and by finding new results in heart rate during unexpected social acceptance from a more negative peer.Show less
