NewsMax.com, FL 04-18-07 Va. Tech Killer A Violent Video Game Fan Virginia Tech mass murderer Cho Seung Hui honed his skill as a deadly marksman by playing violent video games. According to Washington Post Staff Writer David Cho, several Korean youths who knew Cho Seung Hui from his high school days said he was a fan of violent video games, particularly a game called "Counterstrike," a hugely popular online game in which players join terrorism or counterterrorism groups and try to shoot each other using all types of guns. And playing these violent games can do more than help a player improve his skills, they can help transform him from a player to a killer, psychologists say. "Countersrike" is a of the First Person Shooter game genre, where the player becames the participant in simulated murder.

The study's authors add that violent video games may be more harmful than violent television and movies because they are interactive, very engrossing and require the player to identify with the aggressor, the researchers say. "One study reveals that young men who are habitually aggressive may be especially vulnerable to the aggression-enhancing effects of repeated exposure to violent games," according to psychologists Craig A. Anderson, Ph.D., and Karen E. Dill, Ph.D. in their article "Video Games and Aggressive Thoughts, Feelings, and Behavior in the Laboratory and in Life." A second study by the authors revealed that even a brief exposure to violent video games can temporarily increase aggressive behavior in all types of participants. "We found that students who reported playing more violent video games in junior and high school engaged in more aggressive behavior," Anderson, of Iowa State University explained. "We also found that amount of time spent playing video games in the past was associated with lower academic grades in college."
