An Hour of TV a Day Equals a 10 Percent Increase in Attention Problems for Children

Another example comes from a study that looked at bullying. For each hour of TV watched daily by children under age 4, the risk increased 9 percent that they would engage in bullying behavior by the time they started school. This is poor emotional regulation at work. Even taking into account chicken-or-egg uncertainties, the American Association of Pediatrics estimates that 10 percent to 20 percent of real-life violence can be attributed to exposure to media violence.

 

TV also poisons attentions spans and the ability to focus, a classic hallmark of executive function. For each additional hour of TV watched by a child under the age of 3, the likelihood of an attentional problem by age 7 increased by about 10 percent. So, a preschooler who watches three hours of TV per day is 30 percent more likely to have attentional problems than a child who watches no TV.

 

Just having the TV on while no one is watching—secondhand exposure—seemed to do damage, too, possibly because of distraction. In test laboratories, flashing images and a booming sound track continually diverted children from any activity in which they were otherwise engaged, including that marvelous brain-boosting imaginative play we discussed. The effects were so toxic for kids in diapers that the American Association of Pediatrics issued a recommendation that still stands today:

Pediatricians should urge parents to avoid television viewing for children under the age of 2 years. Although certain television programs may be promoted to this age group, research on early brain development shows that babies and toddlers have a critical need for direct interactions with parents and other significant caregivers (e.g., child care providers) for healthy brain growth and the development of appropriate social, emotional, and cognitive skills.
