Eating Concerns and Compulsivity

This study uses a computational task to examine differences in adaptive learning to both rewards and punishments between three groups: those who have recovered from anorexia nervosa, those who score highly on the EAT-26 (Eating Attitudes Test - 26 item version; an eating disorder symptom scale), and healthy controls. This task also allows the examination of pupil response (thought to reflect norepinephrine activity) in response to expected and unexpected wins and losses.
