Several prior studies have identified impaired feedback learning among individuals with AN, but whether it reflects a disturbance in learning from positive feedback (i.e., reward), negative feedback (i.e., punishment), or both, and the extent to which this impairment is related to severity and duration of illness, has not been clarified.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1355617724000237_as2\">\n                    <jats:title>Method:<\/jats:title>\n                    <jats:p>\n                      Participants were female adolescents with AN (\n                      <jats:italic>n<\/jats:italic>\n                      = 76) and healthy teen volunteers (HC;\n                      <jats:italic>n<\/jats:italic>\n                      = 38) between the ages of 12\u201318 years who completed a probabilistic reinforcement learning task.
