Study: Background TV Bad for Early Development

Numerous studies have been critical of TV-watching, saying too much contributes to childhood obesity and, depending on the content, increases aggressive behavior. Now, new research suggests that it's not just what and how often kids are watching TV that parents need to be aware of — it's what they're hearing, too.

According to a recent study, the background noise and distraction of parents' TV-viewing disrupts play behavior and may negatively affect young kids' early cognitive development and ability to focus their attention.

Researchers put 50 1-, 2-, and 3-year-olds, one at a time, and their parents in a room full of age-appropriate toys for an hour. The children played for 30 minutes with a TV turned off and the other 30 minutes with an adult game show (with commercials) turned on.

Calling "background television" (that children don't understand or really pay attention to) an "environmental risk factor in children's development," the study found that the TV interfered with the kids' playing across all three ages. When the TV was on, children in each age range spent less time playing or being focused on their playing (frequently switching toys), even though they never actually looked at the TV for more than a few seconds.

And the tiny tots weren't just missing out on having fun — play is about so much more than just tinkering with toys. In fact, play (and lots of it) is essential to the development of kids' brains and bodies.

That's just one of the reasons why the American Academy of Pediatrics (AAP) recommends zero "screen time" (TV or videos) for tots under 2 and no more than 1 to 2 hours of quality programming (TV, computer, or video games) each day for older kids. Yet, this study points to previous research showing that 75% of U.S. households with very young kids keep the tube on at least half the time, whether anyone's watching it or not.

And although this latest study's researchers admit that "even though the effects of background television on play behavior found in this study are small, they may have a cumulative impact through large amounts of exposure at home."
