Bilinguals must keep two sets of statistics in mind at once and flip between them, one after the other, depending on who they're speaking to. So we asked ourselves, can the babies take statistics on a brand new language?
And we tested this by exposing American babies who'd never heard a second language to Mandarin for the first time during the critical period. We knew that, when monolinguals were tested in Taipei and Seattle on the Mandarin sounds, they showed the same pattern. Six to eight months, they're totally equivalent. Two months later, something incredible happens.
But the Taiwanese babies are getting better, not the American babies. What we did was expose American babies, during this period, to Mandarin. It was like having Mandarin relatives come and visit for a month and move into your house and talk to the babies for 12 sessions. Here's what it looked like in the laboratory. We had to run a control group to make sure that coming into the laboratory didn't improve your Mandarin skills.
So a group of babies came in and listened to English. And we can see from the graph that exposure to English didn't improve their Mandarin. But look at what happened to the babies exposed to Mandarin for 12 sessions. They were as good as the babies in Taiwan who'd been listening for 10 and a half months. What it demonstrated is that babies take statistics on a new language. Whatever you put in front of them, they'll take statistics on.
But we wondered what role the human being played in this learning exercise. So we ran another group of babies in which the kids got the same dosage, the same 12 sessions, but over a television set.
And another group of babies who had just audio exposure and looked at a teddy bear on the screen. What did we do to their brains? What you see here is the audio result — no learning whatsoever — and the video result — no learning whatsoever. It takes a human being for babies to take their statistics. The social brain is controlling when the babies are taking their statistics. We want to get inside the brain and see this thing happening as babies are in front of televisions, as opposed to in front of human beings.
Thankfully, we have a new machine, magnetoencephalography, that allows us to do this. It looks like a hair dryer from Mars. But it's completely safe, completely noninvasive and silent. We're looking at millimeter accuracy with regard to spatial and millisecond accuracy using SQUIDs — these are superconducting quantum interference devices — to pick up the magnetic fields that change as we do our thinking.
We're the first in the world to record babies in an MEG machine while they are learning. So this is little Emma. And she's listening to various languages in the earphones that are in her ears. You can see, she can move around. We're tracking her head with little pellets in a cap, so she's free to move completely unconstrained. It's a technical tour de force. What are we seeing? We're seeing the baby brain. As the baby hears a word in her language, the auditory areas light up, and then subsequently areas surrounding it that we think are related to coherence, getting the brain coordinated with its different areas, and causality, one brain area causing another to activate.
We are embarking on a grand and golden age of knowledge about child's brain development. We're going to be able to see a child's brain as they experience an emotion, as they learn to speak and read, as they solve a math problem, as they have an idea. And we're going to be able to invent brain-based interventions for children who have difficulty learning. Just as the poets and writers described, we're going to be able to see, I think, that wondrous openness, utter and complete openness, of the mind of a child.
