The purpose of this study was to demonstrate that the Approach-Avoidance Simulation method outlining the behavioral tendency towards the representation of chosen objects can portray an evaluation undetectable in explicit attitudes. The assumption that overweight persons approach more strongly the representation of food than persons in the norm of a scale and that persons suffering from anorexia avoid representation of food was confirmed. Similarly overweight persons were headed more strongly for the representation of slim but not emaciated body than persons in the norm of a scale, whereas persons suffering from anorexia were avoiding such a silhouette. The explicit attitude showed the weakest preference of the slim body in the group of overweight persons and the strongest amongst persons suffering from anorexia. The incremental validity of behavioral tendency in the prediction of pertaining to the groups with eating disorders was also demonstrated.
