Abstract: Social comparison is central in human life and can be especially challenging in depression and social anxiety. We assessed event-related potentials and emotions when receiving feedback on both their own and a co-player’s performance, in participants with depression and/or social anxiety (n=63) and healthy controls (n=72). Participants reported more negative emotions for downward (being better than someone else) and upward (being worse) comparisons vs. even outcomes, with these effects being stronger in depression and social anxiety. At the Medial Frontal Negativity, both controls and depressed participants showed enhanced negativity for upward (participant wrong, co-player correct) comparison vs. both the participant and co-player performing wrong. Socially anxious subjects showed the opposite effect, possibly due to greater expectations about being worse than others. The P300 decreased for downward and upward comparisons compared to even outcomes, which may relate to the higher levels of conflict of social inequality. Depressed and socially anxious subjects showed a blunted P300 increase over time in response to the task outcomes, suggesting deficits in allocating resources for the attention of incoming social information. This may relate to difficulties in these disorders in learning how to deal with the cognitive/emotional demands of social comparison.
