The influence of violent video games has been associated with aggressive and/or criminal behaviours in several situations. The present research pretends to emphasize an effect of the exposure to a violent car video game on the activation of aggressive response and post-exposure anger levels. For this, a sample of 47 adolescent people was selected and exposed to a violent video game and a non violent one during 30 minutes. Self-reported anxiety and anger levels were measured before and after the video game exposures, moreover the performance in an indirect task of aggression. A main effect of the age and interaction of this with sex, and the kind of video game were found in the aggressive task. Likewise, a pre-postest effect on state anger levels was observed. On the other hand, a predictor model of the aggressive response elicitation was found with the age and pre-exposure anger as factors. In conclusion, it is outstanding the short term priming effect of violent video games on the aggressive behaviour after violent video game exposure. The existence of modulating factors on the effects of violent contents could clarify their features and help to predict criminal behaviours.
