Violent video games are harming the brains of young teenagers, scientists have found. The effects include increased activity in the part that governs emotional arousal.
This is accompamied by a fall in activity in the region associated with control, focus and concentration. The research was carried out by a team at the University School of Medicine in Indanapolis.
Team leader Professor Vincent Mathews said: "Playing a certain type of violent video game may have different short-term effects than playing a non-violent, but exciting, game."
His study involved 44 adolescents who played a violent or non-violent video game for 30 minutes.
They then performed a series of tasks measuring inhibition, concentration, and emotional responses. The group that played the violent game showed a loss of concentration and self control, coupled with increased emotion. Further research is planned looking at the long-term effects of violent video games on the players.
Do we need scientists with degrees to tell us the obvious?
