Transcript for Baby Talk Could Boost Babies Brain Power
Now to a brand-new study on the surprising benefits of baby talk we go back and forth about it. They're now saying it could have a big impact on boosting the brain power of babies and ABC's linsey Davis has a little one herself right now and did a personal test of the theory. Hello, mike. Do you know who I am? Reporter: Just like in the movie "Look who's talking" we've all spoken in this high-pitched highly exaggerated language known as baby talk or parentese. Oh, yeah, she's gone. Reporter: A new study shows our babies may be benefiting from all that babbling. According to researchers at the university of Washington in Seattle, doling out the da, da, das may improve their speech development even if they can't talk back yet. The first time there's evidence that the brain is working on it well before they've got the true capability. I don't think it's ever too early to talk to the baby. Reporter: Using a noninvasive brain scanner, the study monitored 7 and 11 to 12-month-old babies listening to I series of syllables such as da and Ta and researchers noticed an activation in parts of the brain that coordinated speech production. . Hello, how are you? That's the kind of speech that we think allows babies to mirror what they ought to do. Reporter: So in the interest of brain development -- hi. I make sure my little guy gets an earful of parentese daily. Hi, my precious. Besides, who could resist? For "Good morning America," linsey Davis, ABC news, new York. Oh. That is linsey's bouncing baby boy. We go back and forth. Didn't we do something recently that said read to your children. Bottom line, just keep talking to them as much as you can.
