?? Their study measured the TV habits of 26- year-olds between ages 5 and 15．Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood，compared with an average of more than 2.5 hours for those who had no education beyond high schoo1s．??? ‘

?? In the California study, children with TVs in their rooms but no computer at home scored the lowest，while those with no bedroom TV but who had home computers scored the highest．
