      abstract     = {Depression and social anxiety are common disorders that
                      have a profound impact on social functioning. The need for
                      studying the neural substrates of social interactions in
                      mental disorders using interactive tasks has been
                      emphasized. The field of neuroeconomics, which combines
                      neuroscience techniques and behavioral economics multiplayer
                      tasks such as the Ultimatum Game (UG), can contribute in
                      this direction. We assessed emotions, behavior, and
                      Event-Related Potentials in participants with depression
                      and/or social anxiety symptoms (MD/SA, n = 63, 57
                      females) and healthy controls (n = 72, 67 females),
                      while they played the UG. In this task, participants
                      received fair, mid-value, and unfair offers from other
                      players. Mixed linear models were implemented to assess
                      trial level changes in neural activity. The MD/SA group
                      reported higher levels of sadness in response to mid-value
                      and unfair offers compared to controls. In controls, the
                      Medial Frontal Negativity associated with fair offers
                      increased over time, while this dynamic was not observed in
                      the MD/SA group. The MD/SA group showed a decreased P3/LPP
                      in all offers, compared to controls. These results indicate
                      an enhanced negative emotional response to unfairness in the
                      MD/SA group. Neural results reveal a blunted response over
                      time to positive social stimuli in the MD/SA group.
                      Moreover, between-group differences in P3/LPP may relate to
                      a reduced saliency of offers and/or to a reduced
                      availability of resources for processing incoming stimuli in
                      the MD/SA group. Findings may shed light into the neural
                      substrates of social difficulties in these disorders.},
