Abstract

We investigate whether diminished competitiveness in depression results from alterations in reward valuation, or social preferences. During a resource-contest paradigm, depressive individuals exhibit intact behavioral and neural valuation of social rewards. A model-derived quantification of guilt, and associated VMPFC activation, suggests altered competitiveness may be attributed to increased inequality aversion.
