About 90 percent of U.S. kids ages 8 to 16 play video games, and they spend about 13 hours a week doing so (more if you're a boy). Now a new study suggests virtual violence in these games may make kids more aggressive in real life.
Kids in both the U.S. and Japan who reported playing lots of violent video games had more aggressive behavior months later than their peers who did not, according to the study, which appears in the November issue of the journal Pediatrics.
In the new study, Dr. Craig A. Anderson, Ph.D., of Iowa State University in Ames, and his colleagues looked at how children and teen's video game habits at one time point related to their behavior three to six months later.
The study included three groups of kids: 181 Japanese students ages 12 to 15; 1,050 Japanese students aged 13 to 18; and 364 U.S. kids ages 9 to 12.
In every group, children who were exposed to more video game violence did become more aggressive over time than their peers who had less exposure. This was true even after the researchers took into account how aggressive the children were at the beginning of the study -- a strong predictor of future bad behavior.
The findings are "pretty good evidence" that violent video games do indeed cause aggressive behavior, says Dr. L. Rowell Huesmann, director of the Research Center for Group Dynamics at the University of Michigan's Institute for Social Research in Ann Arbor.
There are two ways violent media can spur people to violent actions, said Huesmann, who has been studying violence in media and behavior for more than 30 years. First is imitation; children who watch violence in the media can internalize the message that the world is a hostile place, he explains, and that acting aggressively is an OK way to deal with it. Also, he says, kids can become desensitized to violence. "When you're exposed to violence day in and day out, it loses its emotional impact on you," Huesmann said. "Once you're emotionally numb to violence, it's much easier to engage in violence."
Just another reminder that parents should pay attention to the types of games their kids are playing and to keep a watchful eye for signs of aggressive behavior...
