| Summary | The purpose of this study is to investigate areas of the brain responsible for 'liking', 'wanting', and learning in adults with eating disorders using brain imaging techniques, computer tasks, a test meal, 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 252 women with an eating disorder (63 AN-restricting type (AN-R), 63 AN-binge eating/purging type (AN-BP), 63 bulimia nervosa (BN)) and 63 healthy controls (HC) aged 18-39. Aim 1: To examine neural differences in 'liking' and 'wanting' in ED relative to HC. Aim 2: To examine differences in instrumental learning for reward and punishment in ED relative to HC. Aim 3: To examine how 'liking' and ' |
