Challenging
Andrew White et al.
Journal of Personality and Social Psychology, forthcoming
Abstract:
Humans have perennially faced threats of violence from other humans and have developed functional strategies for surviving those threats. Five studies examined the relation between threats of violence and agreeableness at the level of nations, individuals, and situations. People living in countries with higher military spending (Study 1) and those who chronically perceive threats from others (Study 2) were more agreeable. However, this threat-linked agreeableness was selective (Studies 3-5). Participants primed with threat were more agreeable and willing to help familiar others but were less agreeable and willing to help unfamiliar others. Additionally, people from large families, for whom affiliation may be a salient response to threat, were more likely than people from small families to shift in agreeableness. Returning to the national level, military spending was associated with increased trust in ingroup members but decreased trust in outgroups. Together, these findings demonstrate that agreeableness is selectively modulated by threats of violence.

Abstract:
Utilizing a 2 (lyrics: present or absent) × 2 (images: present or absent) design, this study examined the unique effects of sexually degrading music videos and music lyrics on males' aggressive behavior toward women, as well as males' endorsement of rape myths and sexual stereotypes. Under the guise of a media memory study, 187 male undergraduate students were randomly assigned to one of four conditions. Despite the many psychological theories predicting an effect, the presentation of sexually degrading content in a visual or auditory medium (or combination thereof) did not significantly alter the participants' aggression and self-reported endorsement of rape myths and sexual stereotypes. The null findings challenge the many corporate and governmental restrictions placed on sexual content in the media over concern for harmful effects.

Another cost of being a young black male: Race, weaponry, and lethal outcomes in assaults
Richard Felson & Noah Painter-Davis
Social Science Research, September 2012, Pages 1241-1253
Abstract:
We examine the effect of the race, age, and gender of victims of assault on the offenders' use of weapons and lethal intent. Evidence from the National Incident Based Reporting System (NIBRS) suggests that offenders are particularly likely to use guns against young black men - a three-way interaction - and to kill black males and young black adults. Black offenders respond more strongly to the victim's race than do white offenders. As a result of these effects, a violent incident between two young black men is about six times more likely to involve a gun than a violent incident between two young white men. We suggest that adversary effects, i.e., an offender's tactical response to the threat posed by adversaries, help explain why violence in black communities tends to be much more serious than violence in white communities.

Journal of Research in Personality, forthcoming
Abstract:
Past research indicates that men are more physically aggressive than women, but very little research has examined mediators of this gender difference. Indeed, the only established finding to date is that one plausible mediator - namely trait anger - shows no reliable gender difference whatsoever. Drawing on sexual selection theory and social learning theories, we predicted that revenge may mediate this gender difference even though anger does not. Three studies using both personality questionnaires (Studies 1 & 2) and objective laboratory measures of aggression (Study 3) provided support for this contention. The results provide some of the first evidence for a reliable mediator of gender difference in physical aggression.

The personality of "aggressive" and "non-aggressive" dog owners
Deborah Wells & Peter Hepper
Personality and Individual Differences, forthcoming
Abstract:
The relationship between pet-keeping and owner personality has attracted considerable attention. Little focus, however, has been directed towards the personality of pet owners in relation to the type of pet owned. This study therefore explored the personality of pet owners in relation to the type of dog breed owned, focusing specifically on owners of breeds widely considered to be "aggressive" versus those more generally perceived as "non-aggressive". One hundred and forty seven owners of "aggressive" (German shepherd dogs, Rottweilers) or "non-aggressive" (Labrador retrievers, Golden retrievers) dog breeds completed the Eysenck Personality Questionnaire short scale. Breed of dog owned was significantly related to owners' psychoticism scores, with people who kept "aggressive" dogs having significantly higher scores on this trait than owners of "non-aggressive" dogs. Dog breed ownership was not significantly related to neuroticism, extraversion or lie scale scores, although male owners of "aggressive" dogs were found to be significantly less neurotic than women who kept "aggressive" or "non-aggressive" dogs. Overall, findings suggest that there is a significant relationship between dog breed ownership and specific personality traits, with owners of breeds widely considered to be "aggressive" harbouring more psychotic tendencies than people who choose to keep dogs with a reputedly less aggressive temperament.

Group Processes & Intergroup Relations, July 2012, Pages 457-470
Abstract:
Ostracism involves two parties: The group doing the exclusion (i.e., sources) and the target of the exclusion. Research on social exclusion has often focused on the targets. The current study, however, considers the experiences of both sources and targets. Members of four-person groups were randomly assigned to the roles of targets or sources of exclusion, and then interacted in a face-to-face setting. Participants' perceptions of themselves and other group members were then evaluated and also compared with control group members. Although targets were negatively affected by exclusion, the sources of exclusion also suffered negative consequences. In addition, these interactions (which were videotaped) were coded by independent judges. The observational data revealed that people use a variety of behaviors to exclude a target, and more stringent forms of exclusion corresponded to more negative outcomes.

Factors Associated With Physical Aggression Among US Army Soldiers
Michael Shayne Gallaway et al.
Aggressive Behavior, forthcoming
Abstract:
There are a growing number of studies that have approximated levels of aggression and associated outcomes among combat veterans returning from Iraq and Afghanistan using brief screening assessments. However, further research to evaluate the relative role of combat exposures and overt physical behaviors is required to further elucidate potential associations between military service, combat deployment, and overt physical aggression. The purpose of the current study was to assess the prevalence of self-reported physical aggression in a sample of US Army soldiers using an adaptation of the Revised Conflict Tactics Scale (CTS2), and examine factors associated with higher levels of aggression. A population-based cross-sectional study was conducted at a single US Army Installation within a sample of active duty US Army soldiers (n = 6,128) from two large units. Anonymous surveys were collected 6 months following deployment to measure overt aggressive behaviors, posttraumatic stress disorder, anxiety, depression, traumatic brain injury, and misuse of alcohol. There were a relatively higher number of minor and severe physical overt aggressive actions reported among soldiers who previously deployed, notably highest among deployed soldiers reporting the highest levels of combat intensity. Soldiers screening positive for the misuse of alcohol were also significantly more likely to report relatively higher levels of physical aggression. This study quantified overt aggressive behaviors and associated factors, showing increasing combat exposures may result in increased physical aggression. Clinicians treating service members returning from combat may consider assessing relative levels of combat.

Bullying and Suicidal Behaviors Among Urban High School Youth
Lisa Hepburn et al.
Journal of Adolescent Health, July 2012, Pages 93-95
Purpose: To determine whether involvement in bullying as a perpetrator, victim, or both victim and perpetrator (victim-perpetrator) was associated with a higher risk of suicidal ideation or suicide attempts among a multiethnic urban high school population in the United States.
Methods: In 2008, a total of 1,838 youth in 9th-12th grades attending public high school in Boston, MA, completed an in-school, self-reported survey of health-related behaviors. Logistic regression was used to evaluate the relationship between bullying behaviors and self-reported suicidal ideation and suicide attempts within the 12 months preceding the survey.
Results: Students who reported having been involved in bullying as a perpetrator, victim, or victim-perpetrator were more likely than those who had not been involved in bullying to report having seriously considered or attempted suicide within the past year. When age, race/ethnicity, and gender were controlled, students who were victim-perpetrators of bullying were at highest risk for both suicidal ideation and suicide attempt.
Conclusions: Urban youth who have been bullied as well as those who have bullied others are at increased risk of suicidal ideation and suicide attempts.

Patterns of adolescent bullying behaviors: Physical, verbal, exclusion, rumor, and cyber
Jing Wang, Ronald Iannotti & Jeremy Luk
Journal of School Psychology, August 2012, Pages 521-534
Abstract:
Patterns of engagement in cyber bullying and four types of traditional bullying were examined using latent class analysis (LCA). Demographic differences and externalizing problems were evaluated across latent class membership. Data were obtained from the 2005-2006 Health Behavior in School-aged Survey and the analytic sample included 7,508 U.S. adolescents in grades 6 through 10. LCA models were tested on physical bullying, verbal bullying, social exclusion, spreading rumors, and cyber bullying behaviors. Three latent classes were identified for each gender: All-Types Bullies (10.5% for boys and 4.0% for girls), Verbal/Social Bullies (29.3% for boys and 29.4% for girls), and a Non-Involved class (60.2% for boys and 66.6% for girls). Boys were more likely to be All-Types Bullies than girls. The prevalence rates of All-Types and Verbal/Social Bullies peaked during grades 6 to 8 and grades 7 and 8, respectively. Pairwise comparisons across the three latent classes on externalizing problems were conducted. Overall, the All-Types Bullies were at highest risk of using substances and carrying weapons, the Non-Involved were at lowest risk, and the Verbal/Social Bullies were in the middle. Results also suggest that most cyber bullies belong to a group of highly aggressive adolescents who conduct all types of bullying. This finding does not only improve our understanding of the relation between cyber bullying and traditional bullying, but it also suggests that prevention and intervention efforts could target cyber bullies as a high-risk group for elevated externalizing problems.

Abstract:
The purpose of this study was to examine two aspects of context for peer aggression: national individualism and distributions of socioeconomic status in the school. School administrators for each school reported on their perceptions of the frequency of bullying and violence in their school. The sample comprised 990 school principals/headmasters from nationally representative samples of schools in 15 countries surveyed as part of the larger IEA Civic Education Study (Torney-Purta, Lehmann, Oswald, & Schulz, 2001). A national context of individualism was associated with violence but not bullying. Schools with high socioeconomic diversity had more bullying than homogeneously low or high socioeconomic status schools. In addition, diverse schools had more violence than affluent schools. Results suggest that bullying and violence should be investigated as separate constructs. Furthermore, contexts, such as national culture and school socioeconomic diversity, are important in understanding the prevalence of bullying and violence in schools internationally.

Perceived Justice and Reactions to Coercive Computers
Daniel Shank
Sociological Forum, June 2012, Pages 372-391
Abstract:
Sociology and justice theories indicate that coercive behavior creates a sense of injustice, but what if a computer is the proximal source of this coercion? I argue that people attribute justice to computers, but do so differently than to humans - people may perceive computers' behavior as unjust, but not as unjust as the same behavior by humans. Likewise, individuals resist and retaliate against coercive behavior, but do so less if the coercer is a computer. These hypotheses are extended from justice studies in social exchange. Specifically, I expand on Molm et al.'s (1993) laboratory experiment of coercion in social exchange, adding a human versus computer identity condition. I conduct a laboratory experiment (N = 121) that replicates Molm et al.'s study and supports the hypotheses on justice, resistance, and retaliation to coercive computers.

Sensory realism and mediated aggression in video games
Eui Jun Jeong, Frank Biocca & Corey Bohil
Computers in Human Behavior, forthcoming
Abstract:
This study investigated whether sensory realism cues in violent games - blood color (red vs. blue), screams of pain (on vs. off), and player perspective (first-person vs. third-person) - affect players' physiological arousal (i.e., skin conductance levels), spatial presence (i.e., sense of being physically "there"), and state aggression in a popular violent game (Half-Life 2), controlling for users' prior game experiences. A path model (N = 160) was examined to see the mediation effects of arousal and presence between realism cues and state aggression. In line with the general aggression model, results showed that realistic blood color and screams increased arousal, but no effect was found for first-person perspective. Presence significantly affected users' state aggression. However, contrary to our expectation based on the excitation transfer theory, arousal did not show any significant effect on aggression. In addition, presence mediated the influence of realistic blood color on state aggression. In the effects of graphic realism of violence on user aggression, presence did a crucial role. Implications and future studies were discussed.

Does exposure to violent video games increase moral disengagement among adolescents?
Alessandro Gabbiadini, Luca Andrighetto & Chiara Volpato
Journal of Adolescence, forthcoming
Abstract:
Several studies have repeatedly shown that violent/action video games increase aggressive tendencies. The present study provides preliminary evidence that exposure to these games also affects the process of moral disengagement. High school students (N = 385) were recruited, and the impact of both recency and frequency of their exposure to the video game Grand Theft Auto IV (GTA; 2008) on moral disengagement was explored. Results showed that exposure to GTA predicted higher levels of moral disengagement. Recency of exposure had a primary impact on the considered mechanisms of moral disengagement. These findings provide insights into a relevant detrimental effect of exposure to video games, to our knowledge not explored yet. Future research is needed to provide evidence of the causal link in the observed relationships.

Research in Developmental Disabilities, November-December 2012, Pages 1905-1913
Abstract:
The present study aimed to examine differences between American juvenile offenders with and without intellectual disability (ID) in offense type and risk factors. The sample consisted of adolescents with ID (n = 102) and without ID (n = 526) who appeared before the courts for a criminal act and for whom the Washington State Juvenile Court Assessment (WSJCA) was completed. Results showed that adolescents with ID had committed more offenses against persons compared to adolescents without ID. Few differences in risk factors were found between juvenile offenders with and without ID in the domains of school, family and use of free time. Juvenile offenders without ID more often had problems in the relationship and alcohol/drugs domain, whereas juveniles with ID more often experienced problems in the domains of attitude, aggression and skills.

Aggressive Behavior, forthcoming
Abstract:
The present two-wave longitudinal study addressed the role of affective empathy and parental support in aggressive and delinquent behavior in a sample of 323 adolescents (158 boys, 165 girls). Self-report questionnaires were used to assess affective empathy, perceived support from parents, delinquency, and aggression. Guided by theories on children's differential susceptibility to socialization, we expected adolescents with different levels of empathy to vary in their responsiveness to parental support. In agreement with our hypothesis, empathy moderated the relation of perceived parental support with aggressive and delinquent behavior. Controlling for the effect of gender and for the stability of aggression and delinquency, higher perceived parental support was predictive of lower levels of aggression at age 15, but only for adolescents high in empathy. Remarkably, adolescents low in empathy not only appeared to benefit less from parental support, but even showed more aggression and delinquency at age 15 when they perceived their parents to be more supportive at age 14.

The role of oxytocin and oxytocin receptor gene variants in childhood-onset aggression
A.I. Malik et al.
Genes, Brain and Behavior, July 2012, Pages 545-551
Abstract:
Aggressive antisocial behaviours are the most common reasons why adolescents are referred to mental health clinics. Antisocial behaviours are costly in social and financial terms. The aetiology of aggressive behaviours is unknown but growing evidence suggests it is heritable, and certain genetic variants have been implicated as contributing factors. The purpose of this study was to determine whether genes regulating the hormone oxytocin (OXT) were associated with aggressive antisocial behaviour. The case-control study sample consisted of 160 cases of children displaying extreme, persistent and pervasive aggressive behaviour. This case sample was compared with 160 adult controls. We used polymerase chain reaction (PCR) to determine the genotype for three oxytocin gene (OXT) single nucleotide polymorphisms (SNPs): rs3761248, rs4813625 and rs877172; and five oxytocin receptor gene (OXTR) SNPs: rs6770632, rs11476, rs1042778, rs237902 and rs53576. Genotypic analyses were performed using stata, while differences in haplotypic and allelic frequencies were analysed using Unphased. We also performed within-case analyses (n = 236 aggressive cases) examining genotypic and allelic associations with callous-unemotional (CU) scores (as measured by the psychopathic screening device). OXTR SNPs rs6770632 and rs1042778 may be associated with extreme, persistent and pervasive aggressive behaviours in females and males, respectively. These and haplotype results suggest gender-specific effects of SNPs. No significant differences were detected with respect to CU behaviours. These results may help to elucidate the biochemical pathways associated with aggressive behaviours, which may aid in the development of novel medications.
