Identifying Mechanistic Pathways to Rigidity Associated with Obsessive-Compulsive Personality Disorder Traits Using a Novel Decision-Making Paradigm

We examined decision-making disruptions underlying rigidity in Obsessive-Compulsive Personality Disorder (OCPD) using a novel translational paradigm. Patterns of reward selectivity and accelerated behavioral adaptation were associated with OCPD traits, showing similarities and distinctions with other disorders (e.g., anorexia nervosa). Findings underscore unique pathways to rigidity, informing future mechanistic research.
