Media violence and the self: The impact of personalized gaming characters in aggressive video games on aggressive behavior

A recent development in video games is that players can design and personalize their own in-game characters. It was predicted that this innovation could lead to elevations in the intensity of the psychological effects of video games. The present study confirmed this hypothesis, revealing that participants who played an aggressive video game using their own, personalized character exhibited higher levels of aggressive behavior than participants who played an aggressive game with a non-personalized character. The aggressive behavior levels of the own-character players also exceeded those of individuals who played a non-aggressive game, regardless of whether or not they used a personalized character. Process analyses revealed that participants playing a violent video game with a personalized game character experienced more arousal and self-activation than they did when playing with an impersonal, default game character, which in turn increased aggressive responses.     

The different effects of personality on prosocial and aggressive driving behaviour in a Chinese sample

Dangerous driving behaviours, as a direct cause of accidents and death, are the focus of considerable research attention. However, unlike unsafe driving behaviours, few studies have explored safe driving behaviours and their effects on road traffic. This study aims to verify the Chinese version of the Prosocial and Aggressive Driving Inventory (PADI) and then investigate the relationship between personality and aggressive/prosocial driving behaviours. A total of 303 licensed drivers were recruited, and they voluntarily and anonymously completed the PADI, the Driving Behaviours Questionnaire (DBQ), and personality scales (anger, sensation-seeking and altruism). The results of this research confirmed the reliability and validity of the Chinese PADI. Most importantly, it was found that different relationships between different personalities and aggressive/prosocial driving behaviours. Specifically, individuals with high altruism exhibited more prosocial driving behaviours, while individuals with high sensation seeking presented more aggressive driving behaviours. The importance of these findings lies in two main potential implications: developing an effective measurement of prosocial driving behaviours in China and providing favourable evidence to guide drivers toward more prosocial driving behaviours.     

Cross-national evidences of a school-based universal programme for promoting prosocial behaviours in peer interactions: Main theoretical communalities and local unicity

The purpose of this study was to evaluate the role of prosocial behaviour against aggression in a school-based universal intervention adapted in two different (non-Western) countries, Colombia and Chile. Using a randomised pretest–post-test design (and controlling for participants' gender and parents' level of education), current results highlighted different effects of a similar programme in both sites. First, the school-based universal programme designed for promoting prosocial behaviours in the peer context obtained a positive cross-national effect on prosocial behaviour rated by three informants (i.e. self, peer and teacher reports). In Colombia, this effect was moderated by the initial level of prosociality of the participants and their level of education. Mediational two-wave model corroborated that the improvement on prosocial behaviours in both countries (moderated in the case of Colombia) predicted significantly lower level of physical aggression. Characteristics of the implementation considering different cultural and historical backgrounds were discussed.     

Prosocial behaviour mediates the relation between empathy and aggression in primary school children

ABSTRACT

The negative association between empathy and aggression has been widely investigated in the literature. However, the role of potential mediators and the extent to which their effects are gender-specific have been given considerably less attention. The present cross-sectional study was therefore aimed at examining the direct and indirect relations between empathy (differentiated into perspective taking and empathic concern), prosocial behaviour and aggression in a sample of 240 primary school children between 8 and 12 years of age. The results showed that perspective taking and empathic concern had indirect (rather than direct) negative effects on aggression by enhancing prosocial behaviour. These indirect paths applied equally well to boys and girls, although significant gender differences were observed in empathic concern, prosocial behaviour and aggression. Possible explanations and differences with previous studies are discussed.     

Aggression in the Laboratory: Problems with the Validity of the Modified Taylor Competitive Reaction Time Test as a Measure of Aggression in Media Violence Studies

Many laboratory studies of aggression use a measure known as the modified Taylor Competitive Reaction Time Test (TCRTT), for which validation studies are lacking. Using sound blasts administered by the participant against a fictional human opponent, the TCRTT also allows for multiple methods of measuring aggression. The validity of the TCRTT was tested in 53 college student participants. Participants took a self-report measure of aggressiveness as well as neuropsychological measures of frontal lobe functioning predictive of aggression. Results were not supportive of the TCRTT's validity and indicated concerns regarding the use of the TCRTT as a measure of aggression. Results suggest that labaratory studies of media violence using the TCRTT are of questionable validity.     

Media violence exposure in aggressive and control adolescents: differences in self‐ and parent‐reported exposure to violence on television and in video games

The purpose of present study was to investigate differences in media violence exposure between groups of adolescents with and without Disruptive Behavior Disorders with Aggressive Features, using a case‐controlled design and multimethod assessment. Samples of 27 adolescents aged 13‐17 with Disruptive Behavior Disorder with Aggressive Features and 27 age‐gender‐IQ matched controls completed a semistructured interview about exposure to violence on television and video games; parents completed a corresponding questionnaire measure. Moderate intercorrelations were found between most self‐ and parent‐report television and video game violence exposure measures. Compared to control adolescents, adolescents with Disruptive Behavior Disorder with Aggressive Features had higher aggregate media violence exposure, higher exposure to video game violence, and higher parent‐reported exposure to television violence. Results show that adolescents and parents agree about the adolescent's level of media violence exposure, that exposure to violence on television tends to be accompanied by exposure to violence in video games, and that the association between media violence exposure and Disruptive Behavior Disorder with Aggressive Features is not due to a spurious effect of gender or IQ.

Peer victimization as a risk factor for schizotypal personality in childhood and adolescence

There has been no prior research on peer victimization and child or adolescent schizotypal personality. This study tests the hypothesis that increased peer victimization is associated with increased schizotypal personality. Schizotypy was assessed using the SPQ-C (Schizotypal Personality Questionnaire-Child) in 3,508 male and female schoolchildren aged 8 to 16 years. All forms of peer victimization (physical, verbal, social manipulation, attack on property) were associated with schizotypal personality in both males and females across all age groups. Significant victimization more than doubled schizotypy scores. It is hypothesized that peer victimization may predispose to paranoid ideation, social anxiety, and lack of close friends, and consequently heightened schizotypal personality.     

Exposure to violence and suicide risk in adolescents: a community study

The prevalence of violence exposure is relatively unexplored in adolescents in European communities, and reports on the association between exposure to community violence and suicidal behavior are rare. The aim of this study was to investigate (1) the prevalence of community violence in a European urban adolescent sample, (2) the relationship between exposure to community violence and suicidal ideation/deliberate self-harm, and (3) the influence of depressive symptoms and aggressive behavior on this relationship. Self-report surveys were administered to a representative school-based sample of 1509 adolescents in Antwerp (Belgium). The prevalence rate of violence exposure was still high but lower than that reported in U.S. communities. Suicidal ideation and deliberate self-harm were both related to violence exposure. The gender-specific influence of depressive symptomatology and aggressive behavior on the association between exposure to violence and suicidal behavior suggests the need for further research.     

Hopelessness as a risk factor for post-traumatic stress disorder symptoms among interpersonal violence survivors

Post-traumatic stress disorder often co-occurs with depression, and they may share common risk factors. One possible common cognitive risk factor is hopelessness. Thus, we examined whether hopelessness was related to symptoms of post-traumatic stress disorder. Participants were 202 female survivors of interpersonal violence. Relationships between self-reported and interviewer-rated measures of hopelessness gathered at 2 weeks post-trauma and self-reported and interviewer-rated symptoms of post-traumatic stress disorder gathered at 2 weeks and 3 months post-trauma were examined. Hierarchical, simultaneous regression analyses that co-varied trauma type revealed that hopelessness was related to self-reported symptoms of post-traumatic stress disorder, both concurrently and prospectively. Follow-up analyses revealed that relationships between hopelessness and symptoms of post-traumatic stress disorder were due almost entirely to shared variance with depression. No relationships were found between hopelessness and interviewer-rated symptoms of post-traumatic stress disorder.     

Intimate partner violence and alcohol use: Exploring the role of drinking in partner violence and its implications for intervention

A large and growing empirical literature reveals a robust relationship between alcohol use and the occurrence of intimate partner violence (IPV). However, the role of alcohol use and intoxication in episodes of IPV, particularly with respect to alcohol's potential causal or facilitative function in the occurrence of partner aggression, remains a source of much controversy and considerable debate. The purpose of this review is to (a) describe briefly IPV and the types of behaviors subsumed under this label, (b) examine evidence for the link between alcohol use and IPV, (c) explicate factors (e.g., antisocial personality disorder) that may moderate this relationship, and (d) discuss the primary conceptual models put forth to explain this association. Recommendations for interventions that consider the relationship between alcohol use and IPV are also provided.     

Digit ratios and preferences for aggressive content in entertainment

Digit ratios (2D:4D) contain information concerning an individual’s propensity towards aggression. Our study adds the first clue to better understanding the relationship between 2D:4D and exposure to aggressive contents in entertainment products. Our findings suggest that individuals with low 2D:4D prefer aggressive contents such as action films, sports telecast, killing and achieving games, hip-hop music, and erotic video clips rather than do individuals with high 2D:4D. Also individuals with low 2D:4D tend to demonstrate less preference for romance films than individuals with high 2D:4D. In addition, we found that low 2D:4D was associated with a preference for sports instead of other genres of entertainment products. Therefore, 2D:4D (a putative correlate of prenatal sex steroids) helps us to better understand the rationale of individuals’ preferences for media violence.     

Lead exposure and child maltreatment as models for how to conceptualize early-in-life risk factors for violence

Although rates of violent crime have been on the decline in the United States for the past two decades, young people—and particularly young men—continue to commit and fall victim to alarmingly high rates of violence. Effective prevention requires data on what the determinants of violence are and when in the life course they emerge. The goal of this review was to identify early-in-life risk factors for violence and to describe (a) who is most affected and (b) effect mechanisms. I focus on abuse and neglect and exposure to lead as risk factors for violence that disproportionately affect young children and that are likely to have causal effects on development. I conclude with future directions for research and intervention.     

Media violence, physical aggression, and relational aggression in school age children: a short-term longitudinal study

Many studies have shown that media violence has an effect on children's subsequent aggression. This study expands upon previous research in three directions: (1) by examining several subtypes of aggression (verbal, relational, and physical), (2) by measuring media violence exposure (MVE) across three types of media, and (3) by measuring MVE and aggressive/prosocial behaviors at two points in time during the school year. In this study, 430 3rd-5th grade children, their peers, and their teachers were surveyed. Children's consumption of media violence early in the school year predicted higher verbally aggressive behavior, higher relationally aggressive behavior, higher physically aggressive behavior, and less prosocial behavior later in the school year. Additionally, these effects were mediated by hostile attribution bias. The findings are interpreted within the theoretical framework of the General Aggression Model.     

Perpetrator and victim perceptions of perpetrator's masculinity as a risk factor for violence: A meta-ethnography synthesis

Men are over-represented as both perpetrators and victims of violence. The purpose of this systematic review was to examine the relationship between masculinity and violence from the perspectives of the perpetrators and victims. In order to provide the best available scientific evidence, four databases were searched and a Critical Appraisal Skills Programme tool was used to evaluate 10 studies. A meta-ethnography approach was also employed to synthesize the selected studies. The analysis revealed a number of reciprocal themes that act as risk factors for violence. This included a masculinization process, available resources, ethnic minority identification and alcohol and substance abuse. This review highlights the need for further research exploring different reciprocal themes and their association with masculinity and violence. Further research in this field could help clinicians improve their practice by helping clinicians widen their discussions about the violence committed by some males. Additional investigations could also improve offender treatment programs, which, in turn, could assist offenders by helping them challenge schemas and cognitive distortions that may precipitate their violence.
