Current and vestigial effects of overweight among women: Fear of fat,attitudinal body image,and eating behaviors

College females completed multiple, standardized measures of their fear of fat, attitudinal body image, and binge eating and dieting. Situational weigh-in measures were taken, including latency to get on the scale and anxiety while being weighed. Based on current weight and a structured weight history questionnaire, three groups were constructed: normal-weight subjects without an overweight history (NW; n=24), normal-weight subjects who were formerly overweight (FOW; n=16), and those currently overweight (OW; n=24). Group comparisons revealed, as expected, that OW females, relative to their NW peers, had more weight-related anxieties, more negative body experiences, and more frequent past-year dieting. Consistent with Stunkard's original proposition, the FOW group regarded their bodies as fatter and less affectively satisfying and expressed more weigh-in anxiety than NW participants. Currently normal-weight FOW subjects seldom differed from the currently OW individuals. Clinical and research implications are considered, particularly with regard to the psychological sequelae of weight loss.     

The effect of context during word perception in schizophrenic patients

Hospitalized chronic and acute schizophrenics were compared with age- and social-status-matched controls on word perception tests to measure the effect of context on recognition thresholds. In Experiment 1 the method of J. Morton (1964, British Journal of Psychology, 55, 165-180) was adopted to see how related and unrelated contexts influenced word recognition thresholds when both context and stimulus word were presented visually. Experiment 2 was an auditory analog of Experiment 1 and in addition the chronic schizophrenics were selected on the basis of a presence or absence of auditory hallucinations. The influence of context on perceptual thresholds was quite normal in all schizophrenics. However, analysis of the incorrect responses elicited showed that some schizophrenic subjects do produce bizarre or irrelevant responses or perseveration to a greater extent than their controls. These results are explained in terms of automatic and strategic modes of information processing. The automatic processes responsible for the adjustment of perceptual thresholds operate normally in schizophrenics but response production which demands strategic selection and editing of responses is prone to malfunction which results in the observed deviations in the normal use of language.     

Generality and topic specificity of cognitive styles

A multitrait-multimethod strategy was used to assess eight structural properties of cognition applied to several classes of objects by 88 university students in Boulder, Colorado, United States, and 80 university students in Kyoto and Otsu, Japan. Each cognitive style was found to display some degree of generality over object classes and also some degree of class specificity. It is concluded that cognitive style depends on the subject, the class of objects considered, and an interaction between the two.     

Group shift to caution at the race track

Group and individual riskiness were compared on $2 “win” best at the race track. Using the standard pretest-posttest risk-shift design, group discussion to unanimous decision was found to produce a cautious shift in group bets.     

Effects of prefeeding on performance with body weight held constant

Two experiments are reported in which rats received either no prefeeding, nutritive substance prefeeding, or nonnutritive substance prefeeding prior to running in a straight alley. The running-speed data supported body weight as an overall measure of hunger drive. Performance was a function of body weight but not stomach weight or associated stomach bulk.
