Recent research reveals that playing prosocial video games increases prosocial cognitions and helpful behaviors [Gentile el al., 2009; Greitemeyer and Osswald, 2009; 2010; 2011]. These results are consistent with social-cognitive models of social behavior [e.g., the "General Learning Model," Buckley and Anderson, 2006]. The social-cognitive learning models suggest that in addition to influencin...

This research examines the relationship between childhood physical and sexual abuse and the types of crimes committed by male adult offenders. We use the method of discriminant prediction to determine whether independent and dependent variables are related in ways that theories predict. Our analyses of data from the Survey of Inmates in State and Federal Correctional Facilities suggest that off...

Violent video game (VVG) use has repeatedly been found to be associated with hostile expectations about others, desensitization to violence, decreased empathy and prosocial behavior, and aggressive thoughts and behaviors. Although these research findings have been widely publicized, VVGs remain the most extensively played games and represent a multi-billion dollar industry. Although VVGs are ty...

We examined the psychometric properties of the Novaco Anger Scale-Provocation Inventory (NAS-PI, 1994 version) in Dutch violent forensic psychiatric patients and secondary vocational students. A confirmatory factor analysis of the subscale structure of the NAS was carried out, reliability was investigated, and relations were calculated between NAS-PI scores and other measures of personality tra...

Despite the rising prevalence of online collective behaviors in Mainland China, there is a dearth of research on their categorization and underlying motivations. To fill this gap, we applied grounded theory to identify the major categories of online collective behaviors in China, and conducted a survey study to understand their underlying motivations. Results show Chinese online collective beha...

This article suggests an alternative line of inquiry - an individual psychology of terrorism that explores how otherwise normal mental states and processes, built on characteristic attitudes, dispositions, inclinations, and intentions, might...

The Youth Level of Service/Case Management Inventory-Screening Version (YLS/CMI-SV) is designed to provide a preliminary estimate of the level of risk for antisocial behaviors as well as an indication of areas for intervention in youth offenders. This study examined the predictive validity of the YLS/CMI-SV for violent, nonviolent, and general recidivism in a sample of 3,264 youth offenders wit...

The Moving to Opportunity (MTO) demonstration assigned housing vouchers via random lottery to public housing residents in five cities. We use the exogenous variation in residential locations generated by MTO to estimate neighborhood effects on youth crime and delinquency. The offer to relocate to lower-poverty areas reduces arrests among female youth for violent and property crimes, relative to...

Postictal psychosis is characterized by a fluctuating combination of thought disorder, auditory and visual hallucinations, delusions, paranoia, affective change, and aggression including violent behavior. We present a case of homicide following a cluster of seizures. The patient's history and postictal behavior were his consistent with postictal psychosis. Contributing factors resulting in homi...

Studies have shown that intimate partner violence (IPV) is associated with poor mental health. But, does women's, and specifically mother's, mental health improve after leaving a union marked by IPV? We used two waves of the Fragile Families and Child Well-Being Study (n = 2610) to examine the association between IPV as measured by controlling and violent behaviors, and maternal mental health a...
