Personality,Parental, and Media Influences on Aggressive Personality and Violent Crime in Young Adults

Debate remains regarding the interaction between predictor variables for aggression, including family environment, media violence, and personality. The current study examined the contributions of gender and personality, exposure to physical abuse and violence in the family, and exposure to media violence in both television and in video games on violent criminal activity. Data from young adults (n = 355) indicated that personality characteristics and direct physical abuse significantly predicted violent crime. Exposure to television and video game violence were not significant predictors of violent crime. These results elucidate the complex interplay between multiple factors related to the etiology of violent crime. These results also call into question the belief that media violence is involved in the etiology of violent crime.     

Association of television violence exposure with executive functioning and white matter volume in young adult males

Prior research has indicated that self-reported violent media exposure is associated with poorer performance on some neuropsychological tests in adolescents. This study aimed to examine the relationship of executive functioning to violent television viewing in healthy young adult males and examine how brain structure is associated with media exposure measures. Sixty-five healthy adult males (ages 18–29) with minimal video game experience estimated their television viewing habits over the past year and, during the subsequent week, recorded television viewing time and characteristics in a daily media diary. Participants then completed a battery of neuropsychological laboratory tests quantifying executive functions and underwent a magnetic resonance imaging (MRI) scan. Aggregate measures of executive functioning were not associated with measures of overall television viewing (any content type) during the past week or year. However, the amount of television viewing of violent content only, as indicated by both past-year and daily diary measures, was associated with poorer scores on an aggregate score of inhibition, interference control and attention, with no relationship to a composite working memory score. In addition, violent television exposure, as measured with daily media diaries, was associated with reduced frontoparietal white matter volume. Future longitudinal work is necessary to resolve whether individuals with poor executive function and slower white matter growth are more drawn to violent programming, or if extensive media violence exposure modifies cognitive control mechanisms mediated primarily via prefrontal cortex. Impaired inhibitory mechanisms may be related to reported increases in aggression with higher media violence exposure.     

Video game violence: A review of the empirical literature

The popularity of video games, especially violent video games, has reached phenomenal proportions. The theoretical line of reasoning that hypothesizes a causal relationship between violent video-game play and aggression draws on the very large literature on media violence effects. Additionally, there are theoretical reasons to believe that video game effects should be stronger than movie or television violence effects. This paper outlines what is known about the relationship between violent video-game playing and aggression. The available literature on virtual reality effects on aggression is discussed as well. The preponderance of the evidence from the existing literature suggests that exposure to video-game violence increases aggressive behavior and other aggression-related phenomena. However, the paucity of empirical data, coupled with a variety of methodological problems and inconsistencies in these data, clearly demonstrate the need for additional research.     

The effects of violent video games on aggression.

Violent content video games such as Mortal Kombat and Doom have become very popular among children and adolescents, causing great concern for parents, teachers, and policy makers. This study cumulates findings across existing empirical research on the effects of violent video games to estimate overall effect size and discern important trends and moderating variables. Results suggest there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively related to time spent playing the games. Directions for future programmatic research on video games are outlined.     

The effect of video game violence on physiological desensitization to real-life violence

Past research shows that violent video game exposure increases aggressive thoughts, angry feelings, physiological arousal, aggressive behaviors, and decreases helpful behaviors. However, no research has experimentally examined violent video game effects on physiological desensitization, defined as showing less physiological arousal to violence in the real world after exposure to video game violence in the virtual world. This experiment attempts to fill this gap. Participants reported their media habits and then played one of eight violent or nonviolent video games for 20 min. Next, participants watched a 10-min videotape containing scenes of real-life violence while heart rate (HR) and galvanic skin response (GSR) were monitored. Participants who previously played a violent video game had lower HR and GSR while viewing filmed real violence, demonstrating a physiological desensitization to violence. Results are interpreted using an expanded version of the General Aggression Model. Links between desensitization, antisocial, and prosocial behavior are discussed.     

Exposure to violent video games and aggression in German adolescents: a longitudinal analysis

The relationship between exposure to violent electronic games and aggressive cognitions and behavior was examined in a longitudinal study. A total of 295 German adolescents completed the measures of violent video game usage, endorsement of aggressive norms, hostile attribution bias, and physical as well as indirect/relational aggression cross‐sectionally, and a subsample of N=143 was measured again 30 months later. Cross‐sectional results at T1 showed a direct relationship between violent game usage and aggressive norms, and an indirect link to hostile attribution bias through aggressive norms. In combination, exposure to game violence, normative beliefs, and hostile attribution bias predicted physical and indirect/relational aggression. Longitudinal analyses using path analysis showed that violence exposure at T1 predicted physical (but not indirect/relational) aggression 30 months later, whereas aggression at T1 was unrelated to later video game use. Exposure to violent games at T1 influenced physical (but not indirect/relational) aggression at T2 via an increase of aggressive norms and hostile attribution bias. The findings are discussed in relation to social‐cognitive explanations of long‐term effects of media violence on aggression. Aggr. Behav. 35:75–89, 2009. © 2008 Wiley‐Liss, Inc.     

Correlates and consequences of exposure to video game violence: hostile personality, empathy, and aggressive behavior

Research has shown that exposure to violent video games causes increases in aggression, but the mechanisms of this effect have remained elusive. Also, potential differences in short-term and long-term exposure are not well understood. An initial correlational study shows that video game violence exposure (VVE) is positively correlated with self-reports of aggressive behavior and that this relation is robust to controlling for multiple aspects of personality. A lab experiment showed that individuals low in VVE behave more aggressively after playing a violent video game than after a nonviolent game but that those high in VVE display relatively high levels of aggression regardless of game content. Mediational analyses show that trait hostility, empathy, and hostile perceptions partially account for the VVE effect on aggression. These findings suggest that repeated exposure to video game violence increases aggressive behavior in part via changes in cognitive and personality factors associated with desensitization.     

First‐Person Shooters and the Third‐Person Effect

A sample of 118 U.S. 6th and 7th graders was used to examine early adolescents’ views of whether video games negatively influence themselves, others of the same age, and younger others. Six specific games ranging in rating from E for Everyone to M for Mature were listed for the early adolescents to respond to, with questions asked about both potential influence and whether young people should be allowed to play the games. Results support a third‐person perception that grew as the rating of the game became more restrictive and as the “other” group in question became younger. The presence of rules set by parents about video game use was a positive predictor of perceptions of influence on self and others.

This is your brain on violent video games: Neural desensitization to violence predicts increased aggression following violent video game exposure

Previous research has shown that media violence exposure can cause desensitization to violence, which in theory can increase aggression. However, no study to date has demonstrated this association. In the present experiment, participants played a violent or nonviolent video game, viewed violent and nonviolent photos while their brain activity was measured, and then gave an ostensible opponent unpleasant noise blasts. Participants low in previous exposure to video game violence who played a violent (relative to a nonviolent) game showed a reduction in the P3 component of the event-related brain potential (ERP) to violent images (indicating physiological desensitization), and this brain response mediated the effect of video game content on subsequent aggressive behavior. These data provide the first experimental evidence linking violence desensitization with increased aggression, and show that a neural marker of this process can at least partially account for the causal link between violent game exposure and aggression.     

Chronic violent video game exposure and desensitization to violence: Behavioral and event-related brain potential data

Numerous studies have shown that exposure to media violence increases aggression, though the mechanisms of this effect have remained elusive. One theory posits that repeated exposure to media violence desensitizes viewers to real world violence, increasing aggression by blunting aversive reactions to violence and removing normal inhibitions against aggression. Theoretically, violence desensitization should be reflected in the amplitude of the P300 component of the event-related brain potential (ERP), which has been associated with activation of the aversive motivational system. In the current study, violent images elicited reduced P300 amplitudes among violent, as compared to nonviolent video game players. Additionally, this reduced brain response predicted increased aggressive behavior in a later task. Moreover, these effects held after controlling for individual differences in trait aggressiveness. These data are the first to link media violence exposure and aggressive behavior to brain processes hypothetically associated with desensitization.

Non‐violent resistance and violence against siblings

A parent‐training approach to the treatment of violence against siblings according to the principles of non‐violent resistance was developed aiming at resisting the violence, providing protection to the victims and reducing escalation between the parents and the violent child.     

The effects of video game play on young children's aggression, fantasy, and prosocial behavior

From the ecological perspective of human development the emergence of significant media may affect children's behavior. It has been suggested that the home computer has the potential to affect young children's behavior, but no published data currently exist to support this hypothesis. However, home computer games have features similar to television. In that vein, research on television and aggression lends itself as a paradigm for studying the effects of video games on young children's behavior. From past television research it may be hypothesized that exposure to violent video games will increase children's aggressive behavior. Twenty-eight children, age 4 to 6 years were observed in a free play setting at baseline, after watching a violent cartoon and after playing “Space Invaders”. Results indicated significant differences in aggressive behavior, relative to baseline behaviors, after watching television and after playing video games. There was no difference between the television and video game conditions. It was concluded that violent video games arouse children in much the same way as violent television cartoons.     

Is Psychopathology the Key to Understanding Why Some Children Become Aggressive When They Are Exposed To Violent Television Programming?

Children with diagnosed psychopathologies may experience aggravation of those illnesses with their exposure to media violence. Children with the most common, often undiagnosed, form of psychopathology—Disruptive Behavior Disorders (DBDs)—manifested changes in heart rate, heart vagal heart tone and other psychophysiological reactions to media violence. Children without a diagnosis did not manifest these same psychophysiological responses. These reactions, or the absence of them, made determining the effect of violent media on children a more reliable measure than acted out behavior, which can be more susceptible to experimenter interpretation and, thus, experimenter bias. This paper explains why there is a difference in the psychophysiological responses between the two groups. Future research should more carefully examine the putative psychological harm violent television content may impose on children with psychological ailments.     

虚拟化身对攻击性的启动效应:游戏暴力性、玩家性别的影响

虚拟化身是个体在虚拟环境中的自我呈现,化身形象是与特定刻板印象相联系的虚拟化身的外在表象。虚拟化身与攻击性的关系已得到证实,但还有一些问题尚需探讨。本研究通过2个实验,采用线索启动的方法,考察了化身形象、游戏暴力性和玩家性别对化身认同和攻击性的影响,以及化身认同和攻击性之间的关系。实验1结果表明:化身形象与游戏暴力性交互影响化身认同和攻击性。在暴力游戏中,化身形象对化身认同和攻击性有显著影响;在非暴力游戏中,化身形象对化身认同的影响边缘显著,但对攻击性无显著影响。对不同化身形象的认同会诱发不同的攻击性,但受游戏暴力性的影响。实验2结果表明:在暴力游戏中,化身形象与玩家性别交互影响化身认同和攻击性。女性在化身认同方面比男性更易受化身形象影响;男性在攻击性方面比女性更易受化身形象影响。对不同化身形象的认同会导致不同的攻击性,但受性别的影响。     

Predictors of Children's Electronic Media Use: An Examination of Three Ethnic Groups

Predictors of media use of children from 1 to 12 years old were examined for 3 ethnic groups (European American, African American, and Hispanic American). Data from the Child Development Supplement to the Panel Study of Income Dynamics representing 1,819 children were used. Models consisting of child characteristics, demographics, family characteristics, and parental well-being predictors accounted for more of the variation in media use (television and video games) by European Americans and Hispanic Americans than they did for African Americans. Generally, variables predicted total use of television similarly for the 3 ethnic groups tested. Parental education predicted use of educational media only for European Americans. Electronic video game use varied almost exclusively by the age and gender of the child. The very different patterns for television and electronic game use suggest that these media may fulfill different functions for children and families.     

Individual and social correlates of aggressive behavior in Lebanese undergraduates: The role of trait emotional intelligence

This study investigates the relationship between Aggressive Behavior and individual factors, namely trait Emotional Intelligence, personality dimensions, emotion regulation and self-worth, as well as social factors, namely accepting/rejecting parenting styles and exposure to violence. The sample consisted of 252 university students in Lebanon (154 females), from 16 to 30 years old. Results from hierarchical regression analyses (controlling for age and gender and in the presence of social and individual predictors) showed that the Self-control and Emotionality factors of trait Emotional Intelligence were significant negative predictors of Aggressive Behavior while controlling for age and gender and in the presence of social and individual predictors). Exposure to violence and openness to experience also predicted Aggressive Behavior. Implications for future research and limitations of the present study are discussed.     

Effects of exposure to sex-stereotyped video game characters on tolerance of sexual harassment

The violent video game literature has previously not extended to the domain of violence against women. The current investigation tested the effects of exposure to sex-typed video game characters versus images of professional men and women on judgments and attitudes supporting aggression against women. Results showed experimental effects of short-term exposure to stereotypical media content on sexual harassment judgments but not on rape myth acceptance. A significant interaction indicated that men exposed to stereotypical content made judgments that were more tolerant of a real-life instance of sexual harassment compared to controls. Long-term exposure to video game violence was correlated with greater tolerance of sexual harassment and greater rape myth acceptance. This data contributes to our understanding of mass media’s role in socialization that supports violence against women.     

Effects of violent video games on aggressive behavior, aggressive cognition, aggressive affect, physiological arousal, and prosocial behavior: a meta-analytic review of the scientific literature

Research on exposure to television and movie violence suggests that playing violent video games will increase aggressive behavior. A meta-analytic review of the video-game research literature reveals that violent video games increase aggressive behavior in children and young adults. Experimental and nonexperimental studies with males and females in laboratory and field settings support this conclusion. Analyses also reveal that exposure to violent video games increases physiological arousal and aggression-related thoughts and feelings. Playing violent video games also decreases prosocial behavior.
