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."'"
It follows that a developing brain exposed to a significant amount of very rapidly changing images (and not even just images but dialog and things and entire scenes) will overdevelop the ability to deal with that speed, with the result that long, drawn out concentration could be almost impossible.
In any case, it's the most cogent biological evidence for the idea of moderation I've ever heard! It's obvious, and it's common sense, but moderation and a large variety of experience for a developing brain is utterly crucial. Just saying this to add to your point regarding parental influence.
