PRT performance, working memory, and pre\u2010task blood glucose were assessed. Group differences were tested using ANOVA and repeated\u2010measures GLM.

Discriminability changed across blocks, but similarly across groups. Accuracy and reaction times did not differ. In AN, blood glucose was positively associated with change in response bias, and this association remained significant after correction. Follow\u2010up regression showed that blood glucose explained 46.7% of the variance in change in response bias.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Findings do not support generalized diagnostic differences in reward\u2010based response bias in AN or BN.
