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.

The recently published study by Suinn, Jorgensen, Stewart, and McGuirk on the proposition that "fears are attitudes" is criticized on two grounds: (a) inadequate and incorrect data analysis and (b) unjustified conclusions drawn from the results. It is further shown that the converse of their proposition, namely, that attitudes are like fears, has more heuristic value and several important implications for social psychology.
