I agree with babies interacting on their own, they are doing problem solving. They have troubles reaching something, or holding something, they adapt and learn, and discover patterns. Definitely true, However, to say a t.v. is just a glowing screen to a child, I disagree with, and I would be inclined to say it's not even all bad.

First off, if you ever put a glowing screen in front of a kid, they don't watch it... they are percieving somethign entertaining (more than just some arbritary screen) whether the content passes to fast for their brains to take anything from it, I may agree with. However, I do think introducing them to new noises, images, colors etc.. is useful in theri development. However, I don't think it's a replacement for traditoinal methods of interaction. In fact, I'd recommend interacting while they watch their sing-along song.

I have no problems with the study, but i'd be surprised if tv watching couldn't be implemented in a useful way.
