[Correction Notice: An erratum for this article was reported in Vol 43(4) of Journal of Experimental Social Psychology (see record 2007-08759-020). The publisher regrets that some of the authors’ corrections were not incorporated. The legend to Fig. 2 should read: “Heart rate at baseline, after playing a video game, and while watching filmed real-life violence for violent and nonviolent video game players. Mean heart rates for violent and nonviolent video game players during the viewing of filmed real-life violence were 70.7 and 68.5, respectively. All means are adjusted for gender. Capped vertical bars denote 1 SE.” Some of the means in Fig. 3 do not correspond to the means in the text, and the legend is missing some information. Fig. 3 should be replaced with the figure and legend given in the erratum. On page 494, in the first paragraph, two F-tests are misreported. The fourth to the last sentence should be replaced with: “Furthermore, nonviolent game participants had a slight (nonsignificant) increase in GSR change while viewing the film, F(1,127)=.52, p>.05, d=.13, whereas violent game participants showed a decrease in GSR, F(1,113)=7.19, p<.05, d=.50.”] 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 20min. 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.
