Cognitive interference due to food cues in childhood obesity.

Investigated specific information-processing biases for food-relevant stimuli in 34 children, Mage = 13 years, SD = 2 years, M = 177% of ideal weight, SD = 24%, who were completing a residential cognitive-behavioral treatment program for severe obesity and 40 matched control children who were not obese, Mage = 13 years, SD = 2 years, M = 103% of ideal weight, SD = 13%. Participants completed a computerized modified Stroop task, which included food words, negative-emotion words, and control words. Results indicated that children in the obesity group displayed a specific interference effect for food words. It is hypothesized that the observed bias in information processing reflects hypersensitivity for food cues, which can initiate or maintain dysfunctional eating behavior.
