Very little is known about the neural circuitry guiding anger, angry rumination, and aggressive personality. In the present fMRI experiment, participants were insulted and induced to ruminate. Activity in the dorsal anterior cingulate cortex was positively related to self-reported feelings of anger and individual differences in general aggression. Activity(More)
Previous measures of aggressive personality have focused on direct aggression (i.e., retaliation toward the provoking agent). An original self-report measure of trait displaced aggression is presented. Exploratory and confirmatory factor analyses provided support for a 3-factor conceptualization of the construct. These analyses identified an affective(More)
Previous work has shown differential amygdala response to African-American faces by Caucasian individuals. Furthermore, behavioral studies have demonstrated the existence of skin tone bias, the tendency to prefer light skin to dark skin. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate whether skin tone bias(More)
Models of stress and health suggest that emotions mediate the effects of stress on health; yet meta-analytic reviews have not confirmed these relationships. Categorizations of emotions along broad dimensions such as valence (e.g., positive and negative affect) may obscure important information about the effects of specific emotions on physiology. Within the(More)
Interpersonal provocation is a common and robust antecedent to aggression. Four studies identified angry rumination and reduced self-control as mechanisms underlying the provocation-aggression relationship. Following provocation, participants demonstrated decreased self-control on an unpleasant task relative to a control condition (Study 1). When provoked,(More)
To assess the effects of adjunctive quetiapine for treatment of refractory symptoms of combat-related post-traumatic stress disorder (PTSD), charts of Vietnam veterans with war-connected PTSD who had been prescribed quetiapine were reviewed. Only patients with symptoms that had not responded to adequate therapy with two or more psychotropic medications(More)
Emerging research suggests that rumination increases risk for negative health outcomes. In the first experiment to investigate cortisol responses during angry rumination, participants were provoked and induced to engage in self-focused rumination, provocation-focused rumination, or distraction. Consistent with social threat theory, self-focused rumination(More)
The manner in which individuals recall negative life events has important affective consequences. The present experiment investigated the effects of emotion regulation strategies on anger experience. One hundred and twenty-one undergraduates recalled an anger-inducing memory and were instructed to engage in either analytical rumination, cognitive(More)
This experiment tested the hypothesis that self-focused attention might increase cortisol release. Social self-preservation theory suggests that social evaluation and associated feelings of shame are associated with cortisol reactivity, whereas one implication of objective self-awareness theory is that self-critical awareness and associated feelings of(More)
Despite the enormous costs associated with unrestrained anger, little is known about the neural mechanisms underlying anger regulation. Behavioral evidence supports the effectiveness of reappraisal in reducing anger, and demonstrates that rumination typically maintains or augments anger. To further understand the effects of different anger regulation(More)
