Do babies get smarter or are smarter parents (hence smarter babies) doing the sign language? I would guess the later, it would be nice if the story would tell you how they did the study. Useful content is *so* over rated.

Yea I don't really know about that IQ increase, but I suspect you are correct that it's the smarter parents using baby sign language. On the positive side, I hear that it makes parents and children much less frustrated. In my developmental psychology class, we played this game where half of us were toddlers and half were mothers. Each of us was given 4 words that we could say and a phrase that we had to get the mothers to understand. I was supposed to convey "I want that red pen." The words I could say were no, okay, mom, and stop. It was very fun but difficult. I'm going to teach my children baby sign language... :)

Why does baby sign language work and learning how to talk not work? I mean why not just each your baby to talk?
It's all because our vocal tracts and physical speach areas of the brain develop more slowly than our bodily movement areas. Thus children can make signs before they are capable of speech. Deaf children in deaf homes go through the same progressions of "learning to speak" sign language, but they do it at a much earlier age.
Ah ha! I did not know that.
