Young children who watch more than two hours a day of television show decreased skills in math and executive functioning—the collective term for cognitive abilities related to attention, focus, and self-control—with low-income children faring the worst compared to children from higher-income families who viewed the same amount of TV. The study was published online in February by the Journal of Developmental and Behavioral Pediatrics. The association between television viewing and a child’s math and executive functioning skills was highest for children in families earning at or below about $21,200 a year.
