M-rated bloody gory video and computer games are most popular among young teens, according to a new study.
M-rated games are actually meant for ages 17 and above, but the study suggests that middle-school children play them frequently to release their anger.
The study was conducted by a team of researchers led by Cheryl K. Olson at the Massachusetts General Hospital's (MGH) Center for Mental Health and Media.
As part of the study, researchers analysed a large sample of 1,254 children from two states who came from various socio-economic, racial/ethnic and geographic groups, so these findings might represent the average middle-school child.
The study found that most 7th and 8th graders (ages 12 to 14), including two-thirds of boys and more than one in four girls regularly played violent M-rated video games 'a lot in the past six months'.
'Grand Theft Auto', which is rated M for blood and gore, intense violence, strong language, strong sexual content, and use of drugs, was the most popular game series among the boys surveyed. Surprisingly, it was also the second most popular series among the girls after 'The Sims', a game that simulates the activities of a virtual family.
The study also noted that just six percent of the sample had not played any electronic games in the previous six months.
Many children played the games to manage their feelings, including anger and stress. Children who played violent games were more likely to play to get their anger out. They were also more likely to play games with strangers on the Internet.
