According to a study done by the British government violent video games do not trigger violent children. A broader look at video games actually means the kids can benefit from playing them.
“The games can improve children’s decision-making and instil ‘positive learning traits’, some research suggests. At least one study argues that make-believe violence helps children ‘conquer fears and develop a sense of identity’, as gruesome fairytales once did.”
The debate between video games = violent children and video games = smart children seems to be reaching an end with increasing reports of increased intelligence thanks to the games.
