Violent imagery in games and TV makes children aggressive

There is an increasing risk that young children who watch violent imagery in computer games and on TV can become aggressive and emotionally disturbed, according to a new report. As the BBC http://www.bbc.co.uk reports, a study by researchers at Birmingham University http://www.bham.ac.uk found that the effect was "small but significant" in the short-term and especially relevant for boys. According to the researchers, the effect was less clear for older children and in the long-term. The review, which is published in The Lancet, said that family and social factors were likely to affect the response too.
