Perfectionism, low self-esteem, and family factors as predictors of bulimic behavior.

A previous study found that self-reported body dissatisfaction, depression, and peer pressure to maintain a thin body shape were significant predictors of bulimic behavior in college women, but that family functioning was not a significant predictor [Eat. Behav. 2 (2001) 323]. The current study examined whether perfectionism, low self-esteem, and a more specific family variable--perceived pressure from the family to be thin--predicted any additional variance in eating-disordered behavior after significant variables from the previous study had been taken into account. As in the previous study, self-reported body dissatisfaction, depression, and peer pressure to maintain a thin body shape were significant predictors of bulimic behavior. Perceived weight-related pressure from the family was also a significant predictor. In contrast, high parental expectations were found to predict lower levels of bulimic behavior and to moderate the effects of peer influence on bulimic behavior. The variables found in this study to be related to bulimic behavior may be useful targets for clinical intervention for women with disturbed eating patterns.

Individual differences in working memory capacity predict visual attention allocation.

To the extent that individual differences in working memory capacity (WMC) reflect differences in attention (Baddeley, 1993; Engle, Kane, & Tuholski, 1999), differences in WMC should predict performance on visual attention tasks. Individuals who scored in the upper and lower quartiles on the OSPAN working memory test performed a modification of Egly and Homa's (1984) selective attention task. In this task, the participants identified a central letter and localized a displaced letter flashed somewhere on one of three concentric rings. When the displaced letter occurred closer to fixation than the cue implied, high-WMC, but not low-WMC, individuals showed a cost in the letter localization task. This suggests that low-WMC participants allocated attention as a spotlight, whereas those with high WMC showed flexible allocation.
