Guarding against hostile thoughts: trait anger and the recruitment of cognitive control.

Trait anger is a robust predictor of the angry and aggressive response to hostile situational input, but it is important to better understand the mechanisms underlying this dimension of personality. The present two studies (total N=106) examined the possibility that individuals low in trait anger systematically recruit cognitive control resources within hostile contexts. These resources would likely be useful in facilitating emotion regulation operations. In support of this cognitive control framework, Experiment 1 found that low (but not high) trait anger individuals exhibited superior response-switching abilities in a hostile stimulus context. Experiment 2 conceptually replicated this pattern using a different cognitive control measure related to flanker interference effects. The convergence of findings across studies provides one likely mechanism for the reduced levels of reactivity at low levels of trait anger. Findings are discussed in relation to broader theories of trait anger and emotion regulation.
