Reward Prediction Error Signaling during Reinforcement Learning in Social Anxiety Disorder

Description: 48 adult participants (24 diagnosed with SAD and 24 age-, gender-, and education-matched healthy controls (HC)) underwent event-related functional magnetic resonance imaging while learning from probabilistic feedback. Crucially, both groups completed two parallel versions of the task: one in which they learned under scrutiny (social observation) and one in which they learned without being overtly evaluated (non-social control condition).
