Playing video games for a short period each day could have a small but positive impact on child development, a study by Oxford University suggests.
Scientists found young people who spent less than an hour a day engaged in video games were better adjusted than those who did not play at all.
But children who used consoles for more than three hours reported lower satisfaction with their lives overall.
The research is published in the journal Pediatrics.
Experimental psychologist Dr Andrew Przybylski analysed British surveys involving 5,000 young people aged 10 to 15 years old.
