Perceptual experiences in anorexia nervosa and obesity.
There is increasing evidence suggesting that the perceptual-cognitive experiences of people with anorexia nervosa and juvenile onset obesity may differ from those of people without eating disorders. The research related to several perceptual-cognitive dimensions is critically examined. These include body image perceptions; perception of hunger and satiety cues; perception of external cues; and certain personality variables which may be related to self-perception. The implications of these perceptual-cognitive variables for the treatment of anorexia nervosa and obesity are discussed. The relative efficacy of some behavioural and medical therapies may be related, in part, to their effects on perceptual-cognitive parameters. Recommendations are also made for investigations to further delineate the role of perceptual-cognitive difficulties in people with eating problems.
