TV Viewing Linked to Attention Problems

oDDmON oUT writes "While your mother may have told you that sitting too close to the TV was bad for your eyes, the folks over at New Scientist are reporting that too much television may be linked to a bad attention span 'The study is not proof that TV viewing causes attention problems, Landhuis notes, because it may be that children prone to attention problems may be drawn to watching television. "However, our results show that the net effect of television seems to be adverse."'"

Yep. It's nowhere near new. I used data like this in a speech I had to do in public speaking around 1979 in high school. When I worked in Special Ed, many teachers had noticed that the kids who talked more about TV were the ones that tended to have less of an attention span. There's a lot of experience that leads one to believe that kids that watch too much TV tend to have an attention span that's about 10-15 minutes, or the length of time between commercials.

On the other hand, I've seen a huge number of kids who are supposedly ADD or ADHD show an amazing attention span when they sit down with a copy of Harry Potter. It makes me wonder if part of the problem with attention spans in school is due to inappropriate expectations for a child's age and boring teachers that just don't have the skills teachers did in years past.

Re:Why is it

[mark-t]

The reason it is more common now than it used to be is two fold: one, our society has improved mechanisms for detecting neurologically atypical activity due to improved social programs and medical technologies; and two, there actually _are_ more people in the world with these disorders than before. The reason for the latter is connected with how medical technology has advanced over the past century or so. Before, people with either mental or physical disabilities would not usually be able to be successful, and thus would not typically survive in a competitive world. These people would have relatively few offspring, and the genes associated with those disabilities would not be very common. Enter ever-more improved medicines, the ability to control or limit the effects of the disabilities, allowing people with the genes associated with them to reproduce as commonly as people with typical human gene structures. The result is that the gene pool contains an increasing amount of "flawed" genetic material, increasing the likelihood that a child would be born with some disorder or another.
