Selective processing of eating-, shape-, and weight-related words in persons with bulimia nervosa.

Abstract

The Stroop color-naming task was used to investigate selective information processing in people with bulimia nervosa. Three cards were used: a target card consisting of words related to eating, weight, and shape; a control word card; and the standard conflicting-color card. Thirty-six patients with bulimia nervosa were compared with a group of age-matched female controls. It was found that the amount of disruption caused to color naming by the target card was significantly greater in the bulimia nervosa group than in the female control group, whereas that caused by the color card was similar in the two groups. The Stroop color-naming task may be a useful objective measure of one aspect of the cognitive disturbance of patients with bulimia nervosa.
