Quote:
Results Watching TV for 3 h or more at 5 years
predicted a 0.13 point increase (95% CI 0.03 to 0.24)
in conduct problems by 7 years, compared with watching
for under an hour, but playing electronic games was not
associated with conduct problems. No associations were
found between either type of screen time and emotional
symptoms, hyperactivity/inattention, peer relationship
problems or prosocial behaviour. There was no evidence
of gender differences in the effect of screen time.
Of course they'll say that this wasn't an American study and therefore is invalid. And violent video games are such an easy scapegoat for politicians that a mere scientific study wouldn't be enough to disrupt their talking points. Still, it's a big step to have a legit study like this to back up the gaming communities reputation.
