Objective: The current research applied the general aggression model (GAM) to explain the relation between negative societal changes (e.g., indicators of a poor economy) on aggression-related outcomes. One correlational and one experimental study tested the relationships between these variables as well as possible mediating mechanisms. Method: In Study 1 (N 193), participants completed several ...

Hostility is associated with an increased risk for cardiovascular disease (CVD). Because central serotonin may modulate aggression, we might expect selective serotonin reuptake inhibitors (SSRIs) to be effective in reducing hostility. Such effects have never been examined in individuals scoring high on hostility who are otherwise free from major Axis I psychopathology according to criteria in t...

BACKGROUND Hostility is associated with a significantly increased risk of age-related disease and mortality, yet the pathophysiological mechanisms involved remain unclear. Here we investigated the hypothesis that hostility might impact health by promoting cellular aging. METHODS We tested the relationship between cynical hostility and two known markers of cellular aging, leukocyte telomere le...

Social hostility is seldom expressed overtly. More often than not, individuals try to get their hostile message across without risking violent altercations. However, subtle and relatively covert hostility is not easy to research. We suggest a novel way with the SoMi paradigm, a social decision making task that offers participants the opportunity to be socially mindful or socially hostile by lea...

BACKGROUND Conflicting findings in the literature with regard to the ability of type A behavior, expressions of anger, or hostility to predict incident coronary heart disease (CHD) have created controversy. In addition, there are no prospective studies relating these characteristics to the development of atrial fibrillation (AF). METHODS AND RESULTS From 1984 to 1987, 3873 men and women, 18 t...

Beginning in sixth grade at an average age of 11.9 years, 416 adolescents and their parents participated in 4 waves of data collection involving family observations and multiple-reporter assessments. Ecological theory and the process-person-context-time (PPCT) model guided the hypotheses and analyses. Lagged, growth curve models revealed that family hostility and peer deviance affiliation predi...

This study investigated the effects of violent video game play and trait hostility on attentional bias towards negatively valenced words. Following video game play, participants completed an emotional Stroop task. Results indicated greater Stroop interference for participants high in trait hostility and for participants playing violent video games. Implications of these findings are discussed w...
