Heterosocial perceptual organization: application of the choice model to sexual coercion.

Luce's (1959, 1963) choice model was used to characterize individual differences in men's perception of women's affect as friendly, sexually interested, sad, or rejecting. Women's clothing styles were associated with differences in the model's parameters. Sensitivity to sadness, rejection, and friendliness declined when women were dressed provocatively, whereas sensitivity to sexual interest increased. Provocative clothing was also associated with an increased bias to assume that positive affect was sexual interest rather than friendliness. Men at risk for perpetrating sexual aggression were less sensitive to women's affect than low-risk men were. They were also more likely than low-risk men to associate provocative clothing with sexual interest, and conservative clothing with friendliness. Results indicate that heterosocial perception may help to predict sexually coercive behavior and may be an important target for intervention.

Illusory correlation for body type and happiness: covariation bias and its relationship to eating disorder symptoms.

OBJECTIVE: The current study investigates covariation bias (illusory correlation) in the perceived association between happiness and body type, as well as the association between covariation bias and eating disorder symptoms. METHOD: Undergraduate women (n = 186) rated pictures of women on a variety of attributes, including happiness, degree of overweight, and attractiveness. Later, they were asked to judge the level of covariation between these attributes that was present in the stimuli that they had rated. Participants also completed the Eating Disorder Examination-Self-Report Questionnaire (EDE-Q). RESULTS: Participants reported that there was a negative association between weight and happiness in the stimuli that they had rated, even though the true correlation in the data was zero. This covariation bias was stronger among participants with higher levels of eating disorder symptoms. DISCUSSION: The results suggest a cognitive bias that may play a role in maintaining and enhancing concerns about shape and weight in symptomatic women.

Short-term outcome of psychiatric inpatients with anorexia nervosa in the current care environment.

OBJECTIVE: The current study describes the short-term outcome of 61 inpatients with anorexia nervosa (AN), utilizing a standardized protocol that could be completed by most patients within the typical length of stay (LOS) in an academic medical center in our geographic area. METHOD: Patients were placed on disorder-specific and medication clinical pathways and completed questionnaires at admission and discharge. Diagnostic, historical, demographic, and treatment-related information was obtained. RESULTS: Treatment was sufficient to resolve acute medical problems, initiate refeeding, and interrupt compensatory behaviors, but continued intensive treatment will be critical to full recovery. Patients were discharged at an average of 85% of ideal body weight (IBW). Twenty patients were discharged against medical advice (AMA). Clinical and demographic variables poorly predicted AMA status. DISCUSSION: Attainable inpatient treatment goals in our care environment appear to be > or = 80% IBW at discharge, resolution of acute medical problems, and interruption of compensatory behaviors. Future research should examine whether shorter LOS increases readmission rates or long-term costs.

Assessing clinically relevant perceptual organization with multidimensional scaling techniques.

Multidimensional scaling (MDS) techniques provide a promising measurement strategy for characterizing individual differences in cognitive processing, which many clinical theories associate with the development, maintenance, and treatment of psychopathology. The authors describe the use of deterministic and probabilistic MDS techniques for investigating numerous aspects of perceptual organization, such as dimensional attention, perceptual correlation, within-attribute organization, and perceptual variability. Additionally, they discuss how formal quantitative models can be used, in conjunction with MDS-derived representations of individual differences in perceptual organization, to test theories about the role of cognitive processing in clinically relevant phenomena. They include applied examples from their work in the areas of eating disorders and sexual coercion.

Modeling individual differences in perceptual and attentional processes related to bulimic symptoms.

Attentional and perceptual differences between women with high and low levels of bulimic symptoms were studied with techniques adapted from cognitive science. Stimuli were pictures of young women varying in body size and facial affect. A multidimensional scaling analysis showed that the high-symptom women were significantly more attentive to information about body size and significantly less attentive to information about affect. In prototype classification tasks, the high-symptom women used significantly more information about body size and significantly less information about affect. There were strong associations between individual differences in attention in the similarity task and decision making in the classification tasks. The study shows the potential utility of cognitive science methods for the study of cognitive factors in psychopathology.
