With the help of functional magnetic resonance imaging, scientists managed to identify metabolic changes in brain activities in teenagers following a 30 minute play of video games.
The research included 44 adolescents who were asked to perform a series of tasks after having to play either a violent or nonviolent
video game.
The study participants were aged 13-17 and had no behavioral problems. One group played a violent game with military combat, while another group played a nonviolent racing game.
The
fMRI screening showed that the violent video games increased activities in areas of the brain linked to emotional arousal, decreased responses in self-control brain regions, focus and concentration.
It seems that playing a violent and a non-violent video game causes different short-term effects on brain functioning. Playing violent video games certainly activates the fight or flight response increasing the stress levels in a player.
Additional studies will determine whether playing violent video games has any long-term impact on the brain.
For the time being, T-rating video games are suitable for children ages 13 and older and may contain violent content, strong language or suggestive themes although many fight over the violent content in such games.
