Much ado about something: Violent video game effects and a school of red herring: Reply to Ferguson and Kilburn (2010).

In this article we reply to C. J. Ferguson and J. Kilburn’s (2010) critique of our meta-analysis on violent video game effects (C. A. Anderson et al., 2010). We rely on well-established methodological and statistical theory and on empirical data to show that claims of bias and misinterpretation on our part are simply wrong. One should not systematically exclude unpublished studies from meta-analytic reviews. There is no evidence of publication or selection bias in our data. We did not purposely exclude certain studies; we included all studies that met our inclusion criteria. Although C. J. Ferguson and J. Kilburn believe that the effects we obtained are trivial in size, they are larger than many effects that are deemed sufficiently large to warrant action in medical and violence domains. The claim that we (and other media violence scholars) are attempting to create a false crisis is a red herring. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Nailing the coffin shut on doubts that violent video games stimulate aggression: Comment on Anderson et al. (2010).

Over the past half century the mass media, including video games, have become important socializers of children. Observational learning theory has evolved into social–cognitive information processing models that explain that what a child observes in any venue has both short-term and long-term influences on the child’s behaviors and cognitions. C. A. Anderson et al.’s (2010) extensive meta-analysis of the effects of violent video games confirms what these theories predict and what prior research about other violent mass media has found: that violent video games stimulate aggression in the players in the short run and increase the risk for aggressive behaviors by the players later in life. The effects occur for males and females and for children growing up in Eastern or Western cultures. The effects are strongest for the best studies. Contrary to some critics’ assertions, the meta-analysis of C. A. Anderson et al. is methodologically sound and comprehensive. Yet the results of meta-analyses are unlikely to change the critics’ views or the public’s perception that the issue is undecided because some studies have yielded null effects, because many people are concerned that the implications of the research threaten freedom of expression, and because many people have their identities or self-interests closely tied to violent video games.

Varying forms of husband sexual aggression: Predictors and subgroup differences.

The relationships between two forms of husband sexual aggression (coercion and threatened/forced sex) and husband physical and psychological aggression were examined among a community sample of 164 couples. A stronger relationship between physical and sexual aggression was obtained than in previous research. Husbands' physical and psychological aggression predicted husbands' sexual coercion, but only physical aggression predicted threatened/forced sex. The more severely physically violent subtypes of the A. Holtzworth-Munroe et al. (2000) typology engaged in the most sexual coercion, and the most violent subtype (generally violent/antisocial) engaged in the most threatened/forced sex. In examining C. M. Monson and J. Langhinrichsen-Rohling's (1998) typology, the existence of a sexually violent-only subtype was documented, physically nonviolent husbands were found to engage in sexual coercion, and sexually and physically violent husbands engaged in the highest level of sexual aggression. The utility of using multiple measures, and both spouses' reports, to assess sexual aggression is emphasized. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The curve is still out there: A reply to Bushman, Wang, and Anderson's (2005) "Is the curve relating temperature to aggression linear or curvilinear?"

This article replies to research conducted by B. J. Bushman, M. C. Wang, and C. A. Anderson (2005) and demonstrates that the results of prior research by E. G. Cohn and J. Rotton (1997) do support the existence of a curvilinear relationship between temperature and aggression when time of day is taken into consideration. The shape of the relationship between temperature and aggression also depends on a number of other factors, including season, amount of social interaction, type of violence, and type of setting. It appears that linear relationships between temperature and aggression identified by B. J. Bushman et al. (2005) are less ubiquitous than might be believed and that the curve is still out there.

Television and aggression: A counterargument.

Cites limitations to the L. D. Eron et al (see record 1973-09034-001) study that suggests that TV violence causes aggression. The Eron et al study dealt with Ss' favorite TV programs and the amount of aggression in them rather than with their actual total amount of exposure to TV violence.

Blazing angels or resident evil? Can violent video games be a force for good?

Violent video games have been a source of controversy in the United States and elsewhere for several decades. Considerable concern has been raised in the public and scientific communities about the alleged deleterious effects of violent games. These concerns may coincide with periodic moral panics about media's influence, particularly on youth. This paper argues that the negative effects of violent games have been exaggerated by some elements of the scientific community, fitting with past cycles of media-focused moral panics. By contrast, potential positive effects of violent video game play have been ignored in the debate on violent games. The current paper considers research in several areas, including aggression, but also the nascent research fields of visuospatial cognition, social networking, and use as educational tools. It is argued that the debate on video game violence should be broadened to include both potential negative and positive effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Television violence and aggression: The causal effect remains.

Replies to criticisms by G. Becker (1972), R. M. Kaplan (1972), and H. Kay (1972) on the article by L. D. Eron et al (see record 1973-09034-001) concerning television violence and aggression. There is no reason to change the conclusion that early exposure to TV violence probably has a causal influence on aggression in males.

Parent–child interaction, television violence, and aggression of children.

Summarized and integrated results of 2 large-scale longitudinal studies (L. D. Eron, see PA, Vol 38:2452; Eron et al, in press). The relationship between TV violence and aggression in Ss was corroborated in 2 different geographical areas of the US and was found to hold for both boys and girls. The causal effect is circular, with TV violence affecting S's aggression and aggressive Ss watching more violent TV. Contributing increments to a S's level of overt aggression were popularity, intellectual ability, aggressive fantasy, extent of physical punishment, rejection by parents, and the tendency of parents to endorse attitudes and behaviors often seen in sociopathic individuals. It is shown that it is possible to intervene to attenuate the relationship between TV violence and aggression with simple tuitional procedures that supercede the influence of the parent variables studied. Important intervening variables in the TV violence–aggression relationship are S's identification with aggressive characters and the extent to which S believes TV portrays reality.

Intelligence, personality, and criminal violence: A multivariate analysis.

The L. R. Huesmann et al (1978) Validity (F)?+?Psychopathic Deviate (Pd)?+?Hypomania (Ma) MMPT index of aggression and A. B. Heilbrun's (see record 1979-25100-001) hypothesis regarding the interaction of intelligence and psychopathy in relation to violent behavior were evaluated with 390 adult male offenders, mean age 26.2 yrs. The F?+?Pd?+?Ma composite did not differentiate significantly between inmates who had been classified according to the violent or nonviolent nature of their most recent offenses, although it was positively correlated with Ss' lifetime total number of violent convictions. Nonetheless, this latter correlation was of extremely small magnitude, and the combination of scales F, Pd, and Ma performed no better than Pd alone. Low levels of intellectual functioning were associated with violent crime in all analyses; however, contrary to Heilbrun, the relationship of intelligence and psychopathy to violence was found to be linear and additive rather than interactive, regardless of whether psychopathy was defined as F?+?Pd?+?Ma or as Pd only.

I wish I were a warrior: The role of wishful identification in the effects of violent video games on aggression in adolescent boys.

This study tested the hypothesis that violent video games are especially likely to increase aggression when players identify with violent game characters. Dutch adolescent boys with low education ability (N=112) were randomly assigned to play a realistic or fantasy violent or nonviolent video game. Next, they competed with an ostensible partner on a reaction time task in which the winner could blast the loser with loud noise through headphones (the aggression measure). Participants were told that high noise levels could cause permanent hearing damage. Habitual video game exposure, trait aggressiveness, and sensation seeking were controlled for. As expected, the most aggressive participants were those who played a violent game and wished they were like a violent character in the game. These participants used noise levels loud enough to cause permanent hearing damage to their partners, even though their partners had not provoked them. These results show that identifying with violent video game characters makes players more aggressive. Players were especially likely to identify with violent characters in realistic games and with games they felt immersed in. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Role of cognitive€motional mediators and individual differences in the effects of media violence on aggression.

Two experiments were conducted to test the hypothesis that observation of media violence elicits thoughts and emotional responses related to aggression. In Experiment 1, highly violent videotapes elicited more aggressive cognitions than did a less violent tape. This effect was moderated by the trait of stimulus screening. In Experiment 2, aggressive cognitions increased with the level of violence in the videotape, and physical assaultiveness influenced this effect. Hostility and systolic blood pressure were higher in response to the most violent video than in response to the other two. Hostility was influenced by emotional susceptibility and dissipation–rumination, and systolic blood pressure was influenced by emotional susceptibility and assaultiveness.

Stress-disorder symptoms in Vietnam and Korean war veterans: A commentary on Thienes-Hontos, Watson, and Kucala.

P. Thienes-Hontos et al (see record 1982-28346-001) concluded that stress disorder is neither unique nor particularly frequent among Vietnam veteran patients. However, the present author suggests that a close examination of their Ss and procedures casts serious doubt on the grounds for this conclusion. Although Thienes-Hontos et al note some of the methodological shortcomings in their study, they underemphasize the degree to which the problems prevent a confident interpretation of the results.

Television violence and children's aggression: Testing the priming, social script, and disinhibition predictions.

The effect of television violence on boys' aggression was investigated with consideration of teacher-rated characteristic aggressiveness, timing of frustration, and violence-related cues as moderators. Boys in Grades 2 and 3 (N?=?396) watched violent or nonviolent TV in groups of 6, and half the groups were later exposed to a cue associated with the violent TV program. They were frustrated either before or after TV viewing. Aggression was measured by naturalistic observation during a game of floor hockey. Groups containing more characteristically high-aggressive boys showed higher aggression following violent TV plus the cue than following violent TV alone, which in turn produced more aggression than did the nonviolent TV condition. There was evidence that both the violent content and the cue may have suppressed aggression among groups composed primarily of boys low in characteristic aggressiveness. Results were interpreted in terms of current information-processing theories of media effects on aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Weaknesses in the television-causes-aggression analysis by Eron et al.

Evaluates the L. D. Eron et al (see record 1973-09034-001) study that suggests a relationship between TV violence and later aggression in boys. The data on the girls do not support the conclusion, the validity of the parental aggression data is faulty, and the data on 3rd-grade viewing of violence are of low validity. Also, programs were categorized for violence on the basis of manifest rather than latent content. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Desensitization to media violence: Links with habitual media violence exposure, aggressive cognitions, and aggressive behavior.

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

On television as a cause of aggression.

Criticizes the use of the peer rating instrument in the L. D. Eron et al (see record 1973-09034-001) study that implied a causal relationship between watching TV violence at age 8 yrs and behaving aggressively at age 18 yrs. Contrary to the Eron et al conclusion, the link between TV violence and aggression has not been clearly established. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Validity of physiological measures of pedophilic sexual arousal in a sexual offender population: A reply to Quinsey and Laws.

V. L. Quinsey and D. R. Laws (see record 1991-10127-001) have criticized the study by G. C. Hall et al (see record 1988-20414-001) of the validity of physiological measures of pedophilic arousal on several methodological grounds. However, Hall et al did use standardized procedures which suggested that such physiological measures lack external validity. Moreover, the Hall et al results are consistent with many other recent physiological studies that have used large, representative populations of sexual offenders.

Causal analysis in R-R studies: Television violence and aggression.

Comments on the L. D. Eron et al (see record 1973-09034-001) study that suggests a relationship between 8–9 yr old boys' preference for highly violent TV programs and high peer ratings of aggression at that age and 10 yrs later. Such causal analyses in response–response (R–R) studies can lead to a spuriously high level of confidence in a hypothesis and to a failure to appreciate cause-and-effect directionality.

Child psychopathy and protective factors: IQ and motivation to change.

Psychopathy in children and adolescents has received increased attention over the past decade. Researchers have been particularly interested in identifying who tomorrow's chronic and serious offenders might be. In addition, researchers have been increasingly interested in determining the etiology of the disorder so as to inform treatment programs. Despite this interest, few studies to date have investigated the protective factors for psychopathy in youth. The current study investigated 140 adolescent boys and girls and the potential protective mechanisms of intelligence and motivation to change. Findings indicated that motivation to change served as a protective factor for general and violent offending at varying levels of psychopathy. Motivation to change also served as a compensatory factor for psychopathy when examining high rates of violent offending. These findings suggest that the cognitive factor of motivation to change may very well be critical in examining developmental pathways to offending in youth and a key consideration for those youth scoring high on psychopathy scales and considering violence as a means of gain.
