It is hard to avoid television if you are a kid. People in the house are usually tuned in to TV - siblings as well as parents. In some homes, the television is perpetually "on" even without anyone watching. It is common for parents and caregivers to use TV as a substitute babysitter. Also, many parents buy videos that they think can make their kids smart. But how does watching TV really affect children?
The bad news is, the majority of experts think that a TV/video-driven culture has bad effects on kids - and may prevent kids from being smart. They cite the following:
- TV viewing takes away the time that your child needs to develop important skills like language, creativity, motor, and social skills. These skills are developed in the kids’ first two years (a critical time for brain development) through play, exploration, and conversation. Your kid’s language skills, for example, do not improve by passively listening to the TV. It is developed by interacting with people, when talking and listening is used in the context of real life.
- TV viewing numbs your kid's mind as it prevents your child from exercising initiative, being intellectually challenged, thinking analytically, and using his imagination.
- TV viewing takes away time from reading and improving reading skills through practice (Comstock, 1991). Kids watching cartoons and entertainment television during pre-school years have poorer pre-reading skills at age 5 (Macbeth, 1996). Also, kids who watch entertainment TV are also less likely to read books and other print media (Wright & Huston, 1995).
- According to Speech and language expert Dr. Sally Ward, 20 years of research show that kids who are bombarded by background TV noise in their homes have trouble paying attention to voices when there is also background noise.
- Kids who watch a lot of TV have trouble paying attention to teachers because they are accustomed to the fast-paced visual stimulation on TV. Kids who watch TV more than they talk to their family have a difficult time adjusting from being visual learners to aural learners (learning by listening). They also have shorter attention spans.
- School kids who watch too much TV also tend to work less on their homework. When doing homework with TV on the background, kids tend to retain less skill and information. When they lose sleep because of TV, they become less alert during the day, and this results in poor school performance.
- TV exposes your kid to negative influences, and promotes negative behavior. TV shows and commercials usually show violence, alcohol, drug use and sex in a positive light. The mind of your kid is like clay. It forms early impressions on what it sees, and these early impressions determine how he sees the world and affect his grown-up behavior. For instance, twenty years of research has shown that children who are more exposed to media violence behave more aggressively as kids and when they are older. They are taught by TV that violence is the way to resolve conflict – as when a TV hero beats up a bad guy to subdue him.
- Kids who watch too much TV are usually overweight, according to the American Medical Association. Kids often snack on junk food while watching TV. They are also influenced by commercials to consume unhealthy food. Also, they are not running, jumping, or doing activities that burn calories and increase metabolism. Obese kids, unless they change their habits, tend to be obese when they become adults.
- Researchers from the University of Sydney report a link between total screen time and retinal artery width in children. Kids with lots of screen time were found to have narrow artery in their eyes, which may indicate heart risk.
