T73. Altered Reinforcement Learning From Reward and Punishment in Women With Anorexia Nervosa

Abstract

Accumulating evidence suggests anorexia nervosa (AN) is characterized by decreased reward reinforcement learning. Increased punishment sensitivity is also implicated in AN, suggesting that altered learning from both reward and punishment may contribute to maladaptive decision-making and decreased motivation to eat. Since little is known about punishment-based learning in AN, we examined whether AN is associated with altered learning from positive and negative outcomes.
