title: Food cues and perceptual distortion of the female body: implications for food avoidance in the early dynamics of anorexia nervosa.
abstract: The present studies concerned a perceptual mechanism that could partially explain the anorexic's severe eating restraint despite continuing hunger. If a woman values a thin body, unrealistic perception of food's fattening effects should increase the aversiveness of ingesting food and foster restraint in eating. The first study considered the perceived thinness/fatness of women's bodies without and with food cues present. College women who (1) shared the stress-generating personality characteristics of anorexics (AP); and (2) judged models as fatter after food cues were introduced (enhancers) reported more stress than AP non-enhancers; no effect of enhancement upon stress was observed in controls. This moderator effect was replicated in a second study. Thus, women with the personality characteristics and high stress that put them at-risk for anorexia also displayed the perceptual distortion involved in the proposed mechanism. Self-ratings verified the same perceptual mechanism in the high-stress AP woman's perception of her own body.
