The False Hope Syndrome of self-change efforts—This is the study of how unrealistic expectations about changing aspects of oneself contribute to the failure of the effort, plus lowered self-esteem and self-image in the person attempting to change. In addition, I am investigating the factors that promote repeated unsuccessful efforts, which include the positive feelings that accompany the initiation of a self-change effort (feeling more in control, feeling that one is doing something about one’s problems), and distorted memories of the initial success that often accompanies a new attempt.
Restrained eating/chronic dieting—I study dieting and its effects on eating and personality, as well as the factors that affect restrained eating. My research has identified chronic dieting as a contributor to binge eating and overeating in response to dysphoria and ego threats, alcohol consumption, anticipated food restriction, anticipated or actual breaking of one’s diet, deprivation of a favorite food (such as chocolate), and overeating by others.
Normal eating behavior—I study social influences on eating, portion size effects, and the effects of emotion on eating. I also study the effects of food restriction in both humans and (occasionally) in rats.
I also study risk factors for eating disorders; individual differences in drug responsiveness; and recognition of emotions in self and others.
Post doctoral fellow(s):
I also generally have 2 fourth year thesis students, and several undergraduate volunteers and work study students doing research in my lab.

People who diet lose touch with their body's natural hunger signals, and often eat based on external cues that have no relationship to how hungry they really are.
