Abstract
Trait aggression is a personality characteristic that has been associated with reduced executive function, which includes lack of impulse control and decreased emotional regulation. Reduced performance on tasks measuring executive function has reliably been associated with reduced frontal lobe function. The aim of the current research was to extend the capacity model of hostility developed by Holland et al. [1] to apply to trait aggression. Men obtaining high and low scores on the Buss and Perry Aggression Questionnaire completed a cognitive and emotional task, and blood pressure measures were taken before and after completion of the tasks. Analysis of the findings indicated that low trait aggressive men evidenced lower systolic blood pressure (SBP) after competing these tasks. Conversely, highly trait aggressive men evidenced significantly higher SBP after completing the same tasks. This indicative of reduced right frontal lobe inhibitory control of the right temporoparietal regions and provides preliminary support for the application of the capacity model to trait aggression.
