I had to do a pretty big research paper on violence and videogames, so I thought I would share some findings. After enough research, one might think that debate about media violence effects would be over. An historical examination of the research reveals that debate concerning whether such exposure is a significant risk factor for aggressive and violent behavior should have been over years ago (Bushman & Anderson, 2001). Four types of media violence studies provide converging evidence of such effects: laboratory experiments, field experiments, cross-sectional correlation studies, and longitudinal studies (Anderson & Bushman, 2002a; Bushman & Huesmann, 2000). But the development of a new genre-electronic video games-reinvigorated the debate.
Two features of video games fuel renewed interest by researchers, public policy makers, and the general public. First, the active role required by video games is a double-edged sword. It helps educational video games be excellent teaching tools for motivational and learning process reasons. But, it also may make violent video games even more hazardous than violent television or cinema. Second, the arrival of a new generation of ultraviolent video games beginning in the early 1990s and continuing unabated to the present resulted in large numbers of children and youths actively participating in entertainment violence that went way beyond anything available to them on television or in movies. Recent video games reward players for killing innocent bystanders, police, and prostitutes, using a wide range of weapons including guns, knives, flame throwers, swords, baseball bats, cars, hands, and feet. Some include cut scenes (i.e., brief movie clips supposedly designed to move the story forward) of strippers. In some, the player assumes the role of hero, whereas in others the player is a criminal.
The new debate frequently generates more heat than light. Many criticisms are simply recycled myths from earlier media violence debates, myths that have been repeatedly debunked on theoretical and empirical grounds. Valid weaknesses have also been identified (and often corrected) by media violence researchers themselves. Although the violent video game literature is still relatively new and small, we have learned a lot about their effects and have successfully answered several key questions.
Several major gaps remain in the violent video game literature. One especially large gap is the lack of longitudinal studies testing the link between habitual violent video game exposure and later aggression, while controlling for earlier levels of aggression and other risk factors. Indeed, of the four major types of empirical studies mentioned earlier, this is the only type missing. There are such studies focusing on television violence but none on video games.
Another gap concerns potential differences in effect sizes of television versus video game violence. There are theoretical reasons to believe that violent video game effects may prove larger, primarily because of the active and repetitive learning aspects of video games. However, this is a very difficult question to investigate, especially with experimental designs. How does one select violent video game and television stimuli that are matched on other dimensions? On what dimensions should they be equivalent? Number of bodies? Amount of blood and gore? Realism of the images? There are a couple of unpublished correlational studies that have compared the effects of television and video game violence on aggression, using comparable measures of violence exposure. Both yielded results suggesting a larger effect of video game violence. But the issue is still not settled today.
