Introduction In the study Neural Basis of Impaired Cognitive Flexibility in Patients with Anorexia Nervosa by SatoY, Saito N, Utsmi A, Aizawa E, Shoji T, et al. (2013), patients with anorexia nervosa were tested on how well their cognitive flexibility, the ability to stop thinking about one concept and be able to transition and think about another. In the study Cognitive Remediation Therapy for Adolescents with Anorexia Nervosa-Treatment Satisfaction and the Perception of Change by Dahlgren C and Stedal K (2017), anorexia nervosa participant’s thoughts on how they liked the treatment and how they perceived it along with the actual net change, results, were investigated. Anorexia nervosa (AN) is defined as a psychiatric disease characterized

Those of which fifteen had AN and the other fifteen were normal women that matched the IQ and age of those who had AN. Of the fifteen women with anorexia nervosa, nine had ANR, while the other six had ANBP. All thirty women were tested using the Wisconsin Card Sorting Test (WCST) to determine their cognitive flexibility and, indirectly, the neural activity in different parts of the brain through an MRI, magnetic resonance imaging. In the WCST there were four reference cards on the screen, one in each corner. Each reference card had elements of color, shape, and number: “three red stars” or “five blue squares”. There was then a test card in the center of the screen and the participant had a controller in their right hand to select which reference card she thought it to go best with elemental wise. Once the participant determined what she thought to be the better selection, an “O” would pop up on the screen if they had answered correctly according to whichever rule was applied. If an “X” were to appear, it meant that the participant got the answer wrong compared to what was being asked by the rule applied. However, to insure a true test in cognitive flexibility none of the participants were told the rules being used prior to the test. There were three rules for matching the cards; color, shape, and number. After five correct responses, the rule would change to a new
