Violent Video Games Linked to Child Aggression
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 shouldn't play games where hunting down and killing people is the goal, says one expert.

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.
The researchers specifically tried to get to the root of the chicken-or-egg problem -- do children become more aggressive after playing video games or are aggressive kids more attracted to violent videos?
It's a murky -- and controversial -- issue. Many studies have linked violence in TV shows and video games to violent behavior. But when states have tried to keep under-18 kids from playing games rated "M" for mature, the proposed restrictions have often been challenged successfully in court.
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.
The U.S. children listed their three favorite games and how often they played them. In the younger Japanese group, the researchers looked at how often the children played five different violent video game genres (fighting action, shooting, adventure, among others); in the older group they gauged the violence in the kids' favorite game genres and the time they spent playing them each week.
Japanese children rated their own behavior in terms of physical aggression, such as hitting, kicking or getting into fights with other kids; the U.S. children rated themselves too, but the researchers took into account reports from their peers and teachers as well.
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.
