The New IQ: Use Your Working Memory to Think Stronger, Smarter, Faster

The American Academy of Pediatrics suggests that children under two years old avoid TV altogether. For those older, they suggest no more than one to two hours a day of educational, nonviolent programs.

In 2004, he published a study that followed more than twelve hundred children for six years, testing them at ages one, three, and seven. What he found was astonishing: the more time children spent watching TV daily at ages one and three, the more likely they were to have attention problems at age seven.
