Abstract: The purpose of the present study was threefold: (1) an examination of the effects of the external rewards of money and verbal reinforcement on the intrinsic motivation to eat; (2) a comparison of these effects between normal weight Individuals and individuals who were between 15%-50% overweight; and (3) an examination of the relationships among intrinsic motivation to eat, the dimension of internal versus external locus of control orientation, and body size. A total of 60 female undergraduates were equally divided into two experimental groups and one control group. Half the subjects in each of the three groups, or 10 subjects per group, were of normal weight and the other half were between 15%-50% overweight. One experimental group was the monetary reward group; the second experimental group was the verbal reinforcement and positive feedback group.
