title: Relationships between hostility, affective ratings of pictures, and state affects during task-induced stress.
abstract: The authors examined the relationship of hostility with (a) affective ratings of pictures and (b) state affects evoked by task-induced stress in 95 healthy men and women 22-37 years of age. Pictures were from the International Affective Picture System (IAPS; P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Stressors included a startle task, mental arithmetic task, and choice-deadline reaction time task. The circumplex model of affect was used to structure the self-reported state affects. The authors found that hostility was associated with displeasure, high arousal, and low dominance ratings of IAPS pictures. Hostility was related to unpleasant affect and unactivated unpleasant affect during the experiment, and subscale paranoia was related to activated unpleasant affect. Findings suggest that participants scoring high on hostility are prone to negative emotional reactions.
