Stop your Child Turning into a Computer Junkie
It's a warm summer's day in the school holidays but the children are not out playing, they are in a darkened room, glued to the TV set, zapping aliens on their Nintendos or surfing the Internet. As their friends ride their bikes, go swimming, play football and walk the dog, the only games your children play are those on the computer, and their only pet is the mouse.
For thousands of children the computer and the TV now dominate lives, turning them into electronic junkies with virtual childhoods where real relations-hips are replaced by artificial ones... Many children, too, begin their viewing early and finish late. Programmes designed to entertain young viewers begin in the early morning, so parents may still be in bed when their children are already up and channel hopping. According to an American study for the U.S. National Institute of Education, ten hours TV watching a week is a healthy level and any more than that results in under performance at school and an unhealthy lifestyle.
Now, with the number of junior junkies growing dramatically, comes the first book aimed at weaning kids off their electronic addiction through a rigorous four week programme.
Joan Anderson, author of Getting Unplugged (John Wiley,£4.99), says that children who watch too much television from an early age have difficulty concentrating, do less well at school, are less active and find it difficulty to form relationships because they spend so much of their time in an imaginary world.
