A new study suggests that the amount of television young children watch may be directly related to attention problems later in school. They may even suffer a condition known as Attention Deficit Disorder or A.D.D. Experts say that A.D.D. involves an over-stimulation of young developing brains and teachers say many children in the United States are showing signs of the disorder. Some education researchers have believed for years that watching television at a very young age could change the normal development of the brain. For example, they say that children who watch a lot of television are not able to sit and read for an extended period of time, show less ability to listen, pay attention, as well as engage in independent problem solving.
This new study tested the idea that television watching by very young children is linked to attention problems by the age of seven. The findings reported that every hour pre-schoolers watch television increases their chances by about ten percent of developing attention deficit problems later in life. For example, children who watched three hours a day were thirty percent more likely to have attention problems than those who watched no television.
One of the researchers said there are other reasons why children should not watch television. Earlier studies have linked it with children becoming too fat and too aggressive. Other experts say the new study is important, but more work needs to be done to confirm the results and better explain the cause and effect.
