The purpose of this study is to investigate areas of the brain responsible for avoidance learning in adults with eating disorders using brain imaging techniques, computer tasks, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 78 women with an eating disorder (26 with anorexia nervosa \[AN\], 26 with bulimia nervosa \[BN\]) and 26 healthy controls (HC) aged 18-39. Aim 1: Evaluate behavioral differences in active and passive avoidance learning in eating disorders and associations with symptoms. Aim 2: Evaluate whether corticostriatal and limbic-prefrontal fMRI BOLD response associated with avoidance learning differs in eating disorders relative to healthy controls and relates to symptoms. Aim 3: Evaluate whether functional connectivity of avoidance learning neural circuity differs in eating disorders relative to healthy controls.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
