It may be a platitude for you folks. A recent research operated by Dr. Craig A. Anderson (Ph.D. of Iowa State University in Ames) suggests that violent games make children more aggressive, reported by cnn.
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 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."
But Dr. Cheryl K. Olson, co-director of the Center for Mental Health and the Media at Massachusetts General Hospital in Boston, isn't convinced.
"It's not the violence per se that's the problem, it's the context and goals of the violence," said Olson, citing past research on TV violence and behavior.
There are definitely games kids shouldn't be playing, she said, for example those where hunting down and killing people is the goal. But she argues that the label "violent video games" is too vague. Researchers need to do a better job at defining what is considered a violent video game and what constitutes aggressive behavior, she added.
"I think there may well be problems with some kinds of violent games for some kinds of kids," Olson said. "We may find things we should be worried about, but right now we don't know enough."
Further, she adds, playing games rated "M" for mature has become "normative behavior" for adolescents, especially boys. "It's just a routine part of what they do," she says.
