People seem to think that a unit of some entity (with certain constraints) is the appropriate and optimal amount. We refer to this heuristic as unit bias. We illustrate unit bias by demonstrating large effects of unit segmentation, a form of portion control, on food intake. Thus, people choose, and presumably eat, much greater weights of Tootsie Rolls and(More)
The stigma-producing effects of "before and after" diet advertisements on a healthy weight sample were examined. Subjects (n = 59) were exposed to a presentation containing either a "before and after" diet ad, or solely the "before" or "after" picture embedded in a different ad. Subjects were then given measures to assess negative attitudes and endorsement(More)
OBJECTIVE To determine the relationship between relative weight and school attendance among elementary schoolchildren. RESEARCH METHODS AND PROCEDURES A total of 1069 fourth to sixth graders from nine elementary schools in the inner city of Philadelphia, PA, were part of an ongoing randomized control trial to assess prevention strategies for obesity.

In a prospective longitudinal study, we examined whether the personality trait of self-control protects against weight gain during the transition from childhood to adolescence. We obtained multi-method, multi-source measures of self-control from a socioeconomically and ethnically diverse sample of 105 fifth-grade students. Height and weight were recorded by(More)
OBJECTIVE To discover a scalable method of food-packaging presentation, which can help reduce per occasion food consumption by making portions sizes more salient and segmented. METHODS Two studies of American undergraduates who ate from tubes of potato chips while watching a movie. In each study, participants ate chips that were either identical (the(More)
College students estimated the weight of adult women from either photographs or a live presentation by a set of models and estimated the calories in 1 of 2 actual meals. The 2 meals had the same items, but 1 had larger portion sizes than the other. The results suggest: (a) Judgments are biased toward transforming the example in question to the size and/or(More)
We report that undergraduate females, unlike males, indicate a high degree of discomfort at the prospect of being weighed in the presence of male or female acquaintances. This discomfort is surprising, in that the other people present already have a good sense of the weight of the female by virtue of being able to see her. An analysis of this discomfort and(More)
