  • Are the effects of unreal violent video games pronounced when playing with a virtual reality system?
  • 2008
  • Ingår i: Aggressive Behavior. - 0096-140X .- 1098-2337. ; 34:5, s. 521-538

    • This study was conducted to analyze the short‐term effects of violent electronic games, played with or without a virtual reality (VR) device, on the instigation of aggressive behavior. Physiological arousal (heart rate (HR)), priming of aggressive thoughts, and state hostility were also measured to test their possible mediation on the relationship between playing the violent game (VG) and aggression. The participants—148 undergraduate students—were randomly assigned to four treatment conditions: two groups played a violent computer game (Unreal Tournament), and the other two a non‐violent game (Motocross Madness), half with a VR device and the remaining participants on the computer screen. In order to assess the game effects the following instruments were used: a BIOPAC System MP100 to measure HR, an Emotional Stroop task to analyze the priming of aggressive and fear thoughts, a self‐report State Hostility Scale to measure hostility, and a competitive reaction‐time task to assess aggressive behavior. The main results indicated that the violent computer game had effects on state hostility and aggression. Although no significant mediation effect could be detected, regression analyses showed an indirect effect of state hostility between playing a VG and aggression.

  • Violent computer games and their effects on state hostility and psychophysiological arousal
  • 2006
  • Ingår i: Aggressive Behavior. - 0096-140X .- 1098-2337. ; 32:2, s. 146-158
  • Tidskriftsartikel (refereegranskat)abstract
    • An experimental study was conducted to investigate the impact of violent computer games on state hostility, state anxiety and arousal. Participants were undergraduate students, aged from 18 to 25 years. Before the experimental sessions, participants filled in self-report measures concerning their video game habits and were also pre-tested for aggressiveness and trait anxiety. Physiological responses (heart rate and skin conductance) were measured during the experiment. After playing, information about state hostility and state anxiety was collected. The results showed that participants who played the violent game reported significantly higher state hostility, and support the assumption that an aggressive personality moderates the effect of playing a violent game on state hostility.

  • Poor motor skills : a risk marker for bully victimization
  • 2013
  • Ingår i: Aggressive Behavior. - : John Wiley & Sons. - 0096-140X .- 1098-2337. ; 39:6, s. 453-461

    • Children who are clumsy are often bullied. Nevertheless, motor skills have been overlooked in research on bullying victimization. A total of 2,730 Swedish adults (83% females) responded to retrospective questions on bullying, their talents in physical education (i.e., coordination and balls skills) and school academics. Poor talents were used as indicators of poor gross motor skills and poor academic skills. A subset of participants also provided information on educational level in adulthood, childhood obesity, belonging to an ethic minority in school and socioeconomic status relative to schoolmates. A total of 29.4% of adults reported being bullied in school, and 18.4% reported having below average gross motor skills. Of those with below average motor skills, 48.6% were bullied in school. Below average motor skills in childhood were associated with an increased risk (OR 3.01 [95% CI: 1.97-4.60]) of being bullied, even after adjusting for the influence of lower socioeconomic status, poor academic performance, being overweight, and being a bully. Higher odds for bully victimization were also associated with lower socioeconomic status (OR 2.29 [95% CI: 1.45-3.63]), being overweight (OR 1.71 [95% CI: 1.18-2.47]) and being a bully (OR 2.18 [95% CI: 1.53-3.11]). The findings indicate that poor gross motor skills constitute a robust risk-marker for vulnerability for bully victimization. Aggr. Behav. 39:453-461, 2013. (c) 2013 The Authors.

  • Predictors and outcomes of persistent or age-limited registered criminal behavior : a 30-year longitudinal study of a Swedish urban population
  • 2009
  • Ingår i: Aggressive Behavior. - New York, N.Y. : John Wiley & Sons. - 0096-140X .- 1098-2337. ; 35:2, s. 164-178
  • Tidskriftsartikel (refereegranskat)abstract
    • This study uses data from the longitudinal research program Individual Development and Adaptation, where an entire school-grade cohort of children in a middle-size Swedish city (n∼1.300) has been followed from ages 10 to 43 and 48 for women and men, respectively. Our findings indicate that the patterns of offending across the life-course differ between genders, where males seem to initiate their offending earlier than females. Further, there are very few women on a persistent offending-trajectory. Focusing on precursors to as well as consequences of offending as indexed in official registers, our results indicate that individuals in the persistent offender group have the most pronounced adjustment problems in school- as well as in middle age. Individual characteristics and behaviors (e.g., aggression, hyperactivity, antisocial behavior) vary systematically between individuals with different developmental offending patterns. The combination of an unstable upbringing and own antisocial behavior seems to be especially predictive for criminality. For persistent offenders, the prevalence of alcohol and psychiatric problems at adult age is high for males and extremely high for females (nine out of ten and six out of ten for each of the two problem types for females). Further, the importance for adjustment of the two-dimensional variation in the number of crimes committed during adolescence and adult age seems to have been surprisingly well captured by the “crude” division into the four offender groups that were used.

  • A multifaceted risk analysis of fathers' self-reported physical violence toward their children
  • 2017
  • Ingår i: Aggressive Behavior. - : Wiley-Blackwell. - 0096-140X .- 1098-2337. ; 43:4, s. 317-328
  • Tidskriftsartikel (refereegranskat)abstract
    • Existing research has shown that child maltreatment is carried out by both mothers and fathers. There is also an extensive body of literature analyzing reasons for mothers' violent behavior. Among fathers, reasons are less well studied, resulting in the lack of a comprehensive picture of paternal child abuse. In this study, 20 child-, parent-, and family-related factors have been included in a combined analysis to assess which of these may pose a risk for fathers' severe violent behavior toward their children. The study is based on merged data from Finland and Sweden, in which an anonymous survey was answered by parents, based on representative samples of parents with 0-12-year-old children. The merged data set included 679 fathers and analyses were carried out using logistic regression models. Six percent of the fathers had committed severe violent acts, that is, slapped, hit, punched, kicked, bit, hit/tried to hit their child with an object or shook (under 2-year-old) their child at least once during the 12 months preceding the survey. Corporal punishment experienced by the fathers when they were children, or used by the father as a method of discipline, strongly increased the likelihood of severe violent acts. The findings emphasize the importance of preventing all forms of corporal punishment in seeking to minimize the occurrence of severe physical violence by fathers toward their children. Aggr.

  • Soccer Referees' Experience of Threat and Aggression : Effects of Age, Experience, and Life Orientation on Outcome of Coping Strategy
  • 2002
  • Ingår i: Aggressive Behavior. - Malden, MA : John Wiley & Sons. - 0096-140X .- 1098-2337. ; 28:4, s. 317-327
  • Tidskriftsartikel (refereegranskat)abstract
    • The present study examined the circumstances pertaining to threat and aggression during soccer matches as experienced by 107 provincial Soccer Association referees. Three sources of aggression were identified—soccer players, coaches/trainers, and spectators—and the main measures included threat and physical and verbal aggression. Several outcomes, including prematch worry and effects on concentration, performance, and motivation, were affected by the incidence of threat and aggression, and these outcomes were found to be affected by the age, degree of experience, and life orientation of the referees. Younger referees were shown to be the most prone to threat and aggression. Referees with a generally pessimistic orientation experienced less motivation, worse performance, and greater problems coping with aggressive behavior from the spectators compared with referees with a generally optimistic orientation.

  • Aggressive Behavior, Related Conduct Problems, and Variation in Genes Affecting Dopamine Turnover
  • 2010
  • Ingår i: Aggressive Behavior. - 0096-140X .- 1098-2337. ; 36:3, s. 158-176
  • Tidskriftsartikel (refereegranskat)abstract
    • A number of dopamine-related genes have been implicated in the etiology of violent behavior and conduct problems. Of these genes, the ones that code for the enzymes that influence the turnover of dopamine (DA) have received the most attention. In this study, we investigated 12 genetic polymorphisms in four genes involved with DA functioning (COMT, MAOA and MAOB, and D beta H in 179 incarcerated male Russian adolescents and two groups of matched controls: boys without criminal records referred to by their teachers as (a) "troubled-behavior-free" boys, n = 182; and (b) "troubled-behavior" boys, n = 60. The participants were classified as (1) being incarcerated or not, (2) having the DSM-IV diagnosis of conduct disorder (CD) or not, and (3) having committed violent or nonviolent crimes (for the incarcerated individuals only). The findings indicate that, although no single genetic variant in any of the four genes differentiated individuals in the investigated groups, various linear combinations (i.e., haplotypes) and nonlinear combinations (i.e., interactions between variants within and across genes) of genetic variants resulted in informative and robust classifications for two of the three groupings. These combinations of genetic variants differentiated individuals in incarceration vs. nonincarcerated and CD vs. no-CD groups; no informative combinations were established consistently for the grouping by crime within the incarcerated individuals. This study underscores the importance of considering multiple rather than single markers within candidate genes and their additive and interactive combinations, both with themselves and with nongenetic indicators, while attempting to understand the genetic background of such complex behaviors as serious conduct problems.

  • The association between childhood maltreatment, mental health problems, and aggression in justice-involved boys
  • 2015
  • Ingår i: Aggressive Behavior. - Hoboken, USA : Wiley-Blackwell. - 0096-140X .- 1098-2337. ; 41:5, s. 488-501
  • Tidskriftsartikel (refereegranskat)abstract
    • The link between childhood maltreatment and adolescent aggression is well documented; yet, studies examining potential mechanisms that explain this association are limited. In the present study, we tested the association between childhood maltreatment and adolescent aggression in boys in juvenile justice facilities (N = 767) and examined the contribution of mental health problems to this relationship. Data on childhood maltreatment, mental health problems, and aggression were collected by means of self-report measures and structural equation models were used to test mediation models. We found that mental health problems mediated the link between maltreatment and aggression. Results demonstrated different pathways depending on the type of aggression examined. The association between childhood maltreatment and reactive aggression was fully mediated by a variety of mental health problems and for proactive aggression the association was partially mediated by mental health problems. We also found that reactive and proactive aggression partially mediated the association between maltreatment and mental health problems. These findings suggest that a transactional model may best explain the negative effects of childhood trauma on mental health problems and (in particular reactive) aggression. In addition, our findings add to the existing evidence that reactive and proactive aggression have different etiological pathways.

  • Five-Year-Olds Punish Antisocial Adults
  • 2015
  • Ingår i: Aggressive Behavior. - 0096-140X .- 1098-2337. ; 41:5, s. 413-420
  • Tidskriftsartikel (refereegranskat)abstract
    • The human tendency to impose costs on those who have behaved antisocially towards third parties (third-party punishment) has a formative influence on societies, yet very few studies of the development of this tendency exist. In most studies where young children have punished, participants have imposed costs on puppets, leaving open the question as to whether young children punish in real third-party situations. Here, five-year-olds were given the opportunity to allocate desirable or unpleasant items to antisocial and neutral adults, who were presented as real and shown on video. Neutral individuals were almost always allocated only desirable items. Antisocial individuals were instead usually allocated unpleasant items, as long as participants were told they would give anonymously. Most participants who were instead told they would give in person did not allocate unpleasant items, although a minority did so. This indicates that the children interpreted the situation as real, and that whereas they genuinely desired to punish antisocial adults, they did not usually dare do so in person. Boys punished more frequently than girls. The willingness of preschoolers to spontaneously engage in third-party punishment, occasionally even risking the social costs of antagonizing an anti-social adult, demonstrates a deep-seated early-developing punitive sentiment in humans.
