We contrast 3 theoretical viewpoints concerning the factors affecting social categorization by race: (a) the classical theory of social categorization highlighting the role of a priori accessibility and situational factors, (b) the classical theory augmented by a principle of competitive category use, and (c) competition between race (but not gender) and coalition with race (but not gender) encoded only as a proxy to coalition. Study 1 documents a confound that renders important portions of previous research difficult to interpret. In Studies 2 and 3, race categorization was stronger than categorization by more weakly accessible categories when situational support in terms of topic relevance was comparable across categories. A situational focus on race further increased race categorization. Race categorization was reduced in the presence of strongly cued cross-cutting coalitions. Race categorization also was depressed when situational factors promoted comparative processing of cross-cutting categories while cues to potential coalitional divisions were held constant (Study 4). Accessibility, topic relevance, and cuing cross-cutting coalitions had the same effects on gender categorization as found for race categorization (Study 5). Taken together, the results suggest that classical theories of social categorization have to be augmented by a principle of competitive category use that is not limited to a competition between race and coalition.

This paper presents results of a long-term evaluation of occupant perception of and satisfaction with thermal comfort in two neighbouring office buildings in Freiburg. They were obtained in field surveys by daily questioning and accompanying measurements in high temporal resolution. One office building is conditioned during summer according to a night-time ventilation concept and the second uses concrete core conditioning and a supply/exhaust ventilation system. Based on the survey data and a regression analysis, a model was calculated to predict the comfort temperature depending on the cooling concept employed. Results were compared to the comfort models of DIN EN 15251

Abstract. Researchers have long argued that aggressive individuals automatically tend to perceive hostile intent in others, even when it is in fact absent (hostile attribution bias). Wilkowski and Robinson (2012) recently showed, however, that aggressive individuals were particularly accurate in the identification of subtle cues of facial anger, indicating greater perceptual sensitivity to anger information rather than a biased perception or interpretation. We tested the generality of this finding in four paradigms with different stimuli. As predicted by Wilkowski and Robinson, the more aggressive participants were, the more accurately they identified subtle aggressive information, whereas accuracy in the identification of nonaggressive emotional information was not a function of self-reported aggressiveness. The discussion focuses on the generality and limitations of the findings.
