Both atteníional bias (using the tuodified Stroop Task) ami autonomic reactivity (skin conductance level) to food-aud body-related information v.'ere assessed in 25 patients with eating disorders (15 patients with anorexia, 10 patients with bulimia) amI 18 women controis. Patients with anorexia showed Ihe greatest inrerference in color-naming foodrelated words. However, on Ihis occasion there were no difierences in body condition, probably because of heterogeneity of clinical samples and because the control group were staff members, so the target information was very familiar to them. The groups differed in their autonomic reacíivity while performing Ihe Stroop. Ihe patients with anorexia responded wiíh higher 5km conductance (p < .036). The discussion focuses on the differential prohíes shown by samples and on the relationship between cognitive biases and autonomic arousal reactivity.

Las anoréxicas mostraron la mayor interferencia al nombrar el color de las palabras relacionadas con la comida, aunque las diferencias no resultaron significativas en cuanto a las palabras relacionadas con el cuerpo. Probablemente este resultado puede deberse tanto a la heterogeneidad de las muestras clínicas como a que el grupo control estaba compuesto por personal del hospital, por lo que la información presentada era igualmente familiar para todos ellos. Los grupos se mostraron diferentes en su reactividad autonómica mientras realizaban la tarea Stroop, siendo las anoréxicas las que mostraron una mayor activación (p < .036). Se analizan los perfiles diferenciales exhibidos por las distintas muestras, así como la relación entre sesgos cognitivos y reactividad autonómica.

A French adaptation of the Stroop colour-naming task was used to investigate selective processing of information related to eating and the body in 92 female subjects: 18 with restricting-type anorexia nervosa (RAs), 25 with binge-eating-type anorexia (BAs), 20 with bulimia nervosa (BNs), and 29 controls (Cs). All participants were significantly slower in colour-naming words related to eating and the body. This suggests that eating and body Stroop effects were not diagnostic category effects. Eating Stroop effect was significantly stronger in eating disordered patients than in Cs, but very similar in RAs, BAs, and BNs. It did not correlate with the body mass index nor with Eating Disorder Inventory (EDI) scores. Body Stroop effect did not differ significantly between groups. However some of our results suggested a tendency for this effect to be higher in BNs, corroborating previous literature data. Body Stroop effect correlated with EDI score in RAs, and with the "body dissatisfaction" subscale score in BNs and BAs. It did not correlate with the body mass index. Further studies are currently being carried out to determine whether inpatient treatment for anorexia nervosa induces significant changes in eating and/or body Stroop effect, and whether such changes might be predictive of clinical outcome.
