Research related to neuropsychological evaluation on eating disorders (ED) has produced diverse results, being more abundant those which study attention, specifically using Stroop Test, both in the standard and the modified versions, using words related to food and body shape. In most of the cases, different clinical groups have not been used in the same research. Studies have not used other tests which evaluate cognitive areas besides those evaluated by Stroop Test; and most of researchers who have measured attention with Stroop Test have focused on measuring latency and not interference. Some studies have found deficits in attention, executive functions, and memory in patients with ED; however, other studies have not found deficits in attention. Because of this evidence, the present study proposed that patients with ED would show deficits in selective attention, perseverative thinking, working memory, and executive planning, compared to a control group without ED. Participants included 26 female patients with bulimia nervosa (BN) and 10 female patients with anorexia nervosa (AN), matched in age and education by the control group (n = 36). All patients met eating disorders criteria, and did not have a history of neuropsychological evaluation. Four neuropsychological tests were individually administered in two sessions with a counterbalanced approach: 1. Wisconsin Card Sorting Test, 2. Stroop Colors Test (developed in the program E-Prime with words related to food and body shape), 3. Rey-Osterriet
