Distinctions Between Two Expectancies in the Prediction of Maladaptive Eating Behavior

In this longitudinal study, the authors provide support for the validity of the claim that differences in the nature of the reinforcement that adolescent girls expect from eating contribute to the development of different forms of maladaptive eating. The learned expectancy that eating is pleasurable and rewarding predicted higher levels of social/celebratory overeating across the first year of middle school but did not predict higher levels of clinical binge eating. In contrast, the expectancy that eating helps one manage negative affect predicted higher levels of binge eating but not of social/celebratory overeating across the same time period (n = 394). The results also supported a reciprocal model in which binge eating predicted higher levels of the expectancy that eating will manage negative affect but not that eating is pleasurable and rewarding; conversely, social/celebratory overeating predicted higher levels of the expectancy that eating is pleasurable and rewarding but not that eating will manage negative affect.     

Negative urgency: a personality predictor of externalizing behavior characterized by neuroticism, low conscientiousness, and disagreeableness

Negative urgency, the tendency to act rashly when distressed, is characterized by high Neuroticism, low Conscientiousness, and low Agreeableness. Because of this set of characteristics, the authors hypothesized that (1) negative urgency (NU) is a particularly important predictor of externalizing dysfunction; (2) traits that reflect primarily high Neuroticism predict internalizing dysfunction; and (3) traits that reflect primarily low Conscientiousness predict those types of externalizing dysfunction that include intense affect less strongly than does NU. In three studies, the authors showed that negative urgency concurrently predicted alcohol dependence symptoms in disordered women, drinking problems and smoker status in preadolescents, and aggression, risky sex, illegal drug use, drinking problems, and conduct disordered behavior in college students. High Neuroticism traits predicted internalizing dysfunction but predicted none of these externalizing criteria beyond negative urgency. Low Conscientiousness did not add to prediction from negative urgency, except in a few cases. The tendency toward affect-driven rash action may underlie many externalizing behaviors.     

Exploring the social aspects of goose bumps and their role in awe and envy

Both awe and envy are emotions that can result from observing a powerful other, but awe should stabilize social hierarchies while envy should undermine them. Three studies explored how the physiological reaction of goose bumps might help in understanding these distinctive reactions to powerful others, as goose bumps should be associated with awe rather than envy. In Study 1, participants kept a four-week journal and made a detailed entry each time they experienced goose bumps. Goose bumps resulting from the emotion of awe were the second most frequently occurring type after reactions to cold. Consistent with understanding awe as an emotional reaction to powerful or superior others (Keltner and Haidt in Cogn Emot 17:297?C314, 2003), many of these experiences had social triggers. In Study 2, accounts of goose bumps resulting from exposure to powerful or superior others contained greater awe than envy. Also, the intensity of goose bumps was positively correlated with awe and negatively correlated with envy. In Study 3, accounts of awe contained more goose bumps than accounts of envy, and goose bumps were positively correlated with awe.
