We propose, develop, and analyze a mathematical model of intergroup attitudes in a community that is divided between two distinct social groups (which may be distinguished by religion, ethnicity, or some other socially distinguishing factor). The model is based on very simple premises that are both intuitive and justified by sociological research. We investigate the behavior of the model in var...

BACKGROUND Psychiatric patients showing risk to themselves or others can be involuntarily hospitalised. No data is available on whether following hospitalisation there is a reduction in psychopathological indicators of risk such as suicidality and hostility. This study aimed to assess changes in suicidality and hostility levels following involuntary admission and their patient-level predictors....

Participants completed the Cook-Medley Hostility questionnaire an...

However, little research has been conducted in populations at high risk for cardiovascular disease. The aim of the present study was to assess the relationship between hostility and acute stress responsivity in individuals with Type 2 diabe...

Objective. To date, no studies have directly examined the effects of cognitive trait hostility on prospectively assessed sleep quality. This is important as individuals with heightened trait hostility demonstrate similar patterns of reactivity to perceived stressors as is often reported by poor sleepers. The present study hypothesized that increased trait hostility is associated with poorer sub...

This study investigated the effects of trait-level hostility, interface types, and character identification on aggressive thoughts and overall game experience after playing a violent video game. Results showed that the mapping interface made participants with high trait-level hostility more readily accessible to aggressive contracts, yet it did not have any significant impact for participants w...

Orally-administered surveys were conducted with 117 mothers and 98 fathers for the first year of data collection, and again a year later with 107 mothers and 83 fathers. Path analyses showed that mothers' re...
