Scientists looked at the brain wiring of a group of under-fives to reach their conclusion.
On average, the children were introduced to screens at 18 months old and used such devices for 1.5 hours per day. Some 60 percent of the children had their own device, and 41 percent had a T.V. or portable device in their bedroom.
Dr. John Hutton, director of the Reading and Literacy Discovery Center at Cincinnati Children's and lead author of the study, told:"This is the first study to document associations between higher screen use and lower measures of brain structure and related skills in preschool-age children." "Prior research shows better language development if screen media use is predominantly educational, programs such as"The best explanation of the findings might well be that children with poorer development in language-related brain areas are more drawn to screen media," argued Anderson.
Screen time may be cutting into this time, and"that creates the relationship, between screens and language tracts, not the screen itself," he said.at the University of Oxford, said in a statement:"Overall, this is a small study on a sample of preschool children from advantaged backgrounds who show no signs of language or educational difficulties."
