Playing video games increases aggression in some children and young adults and normalizes killing, some doctors said. Snyder said exposure to violence in video games can desensitize a teen to the real thing. "Exposure to violent video games, even E rated video games, increases aggressive thoughts, increases pro-social behavior and increases general arousal," said Dr. Greg Snyder. "Then, when they're done playing, that's all that's on their mind. Kill. Kill. Kill. In the news there was a MURDER where a young person acted out what he saw on the video game he was playing. And people say that video games do not affect a young person??? Research shows that as much as 92% of children between 4 and 17 years of age play video games.
More than 12% of children aged 10 to 14 are watching R-rated violent movies Studies have also shown a twelve percent increase in aggressive behavior after watching violent television. Over sixty percent of television shows being shown in prime time contain some form of violence. More than one thousand scientific studies and reviews conclude that significant exposure to media violence increases the risk of aggressive behaviour in certain children, desensitizes them to violence and makes them believe that the world is a meaner and scarier place than it is.
