It's nice that there's science to back it up, but whatever happened to simple logic?? If children are not taught to concentrate (on reading, on tasks, on paying attention, on sitting still, on entertaining themselves, etc.), then why in the world do we expect them to magically have that skill later in life?? Do people really think that parking their kids in front of the TV is going to teach them anything other than that life comes in 5 minute bursts which is interrupted on a continual basis? *rolls eyes* Kids are, to a great extent, what you teach them and what you expose them to.
I've been saying for years that it is parents, through what they expose children to and a serious lack of effort and expectation in critical areas, that have been teaching children to be this way. Heh - now there's proof.
In the end, all it takes is a little common sense.
...scientist with common sense...
