Effect of trait anger on cognitive processing of emotional stimuli.

In the present experiment, the authors examined whether trait anger was associated with cognitive biases for anger-related semantic stimuli. Fifty-two undergraduate students completed the Trait Anger Scale (TAS; C. D. Spielberger, G. Jacobs, S. Russell, & R. Crane, 1983), and those reporting TAS scores in the upper (n = 17) or lower (n = 13) quartiles of the sample were assigned to high- and low-anger groups, respectively. The 30 participants then engaged in a lexical decision task that presented various emotion words, neutral words, and nonwords. Results indicated that individuals who reported high levels of trait anger displayed facilitative biases in the processing of semantic anger-related stimuli. This predisposition to more readily process anger-related information may underlie their propensity to experience intense feelings of anger when provoked.
