Modification of caloric intake in anorexia nervosa: an experimental analysis

The effects of feedback, reinforcement, and increased food presentation on caloric intake were sequentially examined in an experimental single-case design with an anorexia nervosa patient. Although feedback on weight and a point-reinforcement system for weight gains led to increased consumption, augmenting the amount of food presented in combination with feedback and reinforcement resulted in the most dramatic change in caloric intake.
