In Dela Cruz English Club, we have been using a method known as "DCEC Method." This method involves the use of the right brain and mimicking the sounds a learner hears... just like a baby. That is why DCEC learners are always encouraged to listen to the audio CD provided to them and read the text aloud several times on a regular basis.
In a recent TED Talk show, Patricia Kuhl, a co-director of the Institute for Brain and Learning Sciences at the University of Washington, talked about ability of babies to absorb language. According to their study, babies are geniuses when it comes to languages. They take "statistics" of a language as they listen. They are like little scientists on their own.
Based on their findings, one's ability to master a language starts to decline when we hit the 7 year old mark. It goes downhill from there. But this should not discourage adults. We should follow and copy how babies do it, through listening and mimicking... just like the DCEC method. So, this is another proof that our method really works. Come and see for yourself.

I want you to take a look at this baby. What you're drawn to are her eyes and the skin you love to touch. But today I'm going to talk to you about something you can't see, what's going on up in that little brain of hers. The modern tools of neuroscience are demonstrating to us that what's going on up there is nothing short of rocket science. And what we're learning is going to shed some light on what the romantic writers and poets described as the "celestial openness" of the child's mind.
What we see here is a mother in India, and she's speaking Koro, which is a newly-discovered language. And she's talking to her baby. What this mother -- and the 800 people who speak Koro in the world -- understand that, to preserve this language, they need to speak it to the babies. And therein lies a critical puzzle. Why is it that you can't preserve a language by speaking to you and I, to the adults? Well, it's got to do with your brain. What we see here is that language has a critical period for learning. The way to read this slide is to look at your age on the horizontal axis. (Laughter) And you'll see on the vertical your skill at acquiring a second language. Babies and children are geniuses until they turn seven, and then there's a systematic decline. After puberty, we fall off the map. No scientists dispute this curve, but laboratories all over the world are trying to figure out why it works this way.
Work in my lab is focused on the first critical period in development -- and that is the period in which babies try to master which sounds are used in their language. We think by studying how the sounds are learned, we'll have a model for the rest of language, and perhaps for critical periods that may exist in childhood for social, emotional and cognitive development. So we've been studying the babies using a technique that we're using all over the world and the sounds of all languages. The baby sits on a parent's lap, and we train them to turn their heads when a sound changes -- like from "ah" to "ee". If they do so at the appropriate time, the black box lights up and a panda bear pounds a drum. A six-monther adores the task.
What have we learned? Well, babies all over the world are what I like to describe as citizens of the world; they can discriminate all the sounds of all languages, no matter what country we're testing and what language we're using. And that's remarkable because you and I can't do that. We're culture-bound listeners. We can discriminate the sounds of our own language, but not those of foreign languages. So the question arises, when do those citizens of the world turn into the language-bound listeners that we are? And the answer: before their first birthdays. What you see here is performance on that head turn task for babies tested in Tokyo and the United States, here in Seattle, as they listened to "ra" and "la" -- sounds important to English, but not to Japanese. So at six to eight months the babies are totally equivalent. Two months later something incredible occurs. The babies in the United States are getting a lot better, babies in Japan are getting a lot worse, but both of those groups of babies are preparing for exactly the language that they are going to learn.
So the question is, what's happening during this critical two-month period? This is the period for sound development, but what's going on up there? So there are two things going on. The first is that the babies are listening intently to us, and they're taking statistics as they listen to us talk -- they're taking statistics. So listen to two mothers speaking motherese -- the universal language we use when we talk to kids -- first in English and then in Japanese.
(Video) English Mother: Ah, I love your big blue eyes -- so pretty and nice.
Japanese Mother: [Japanese]
Patricia Kuhl: During the production of speech, when babies listen, what they're doing is taking statistics on the language that they hear. And those distributions grow. And what we've learned is that babies are sensitive to the statistics, and the statistics of Japanese and English are very, very different. English has a lot of R's and L's the distribution shows. And the distribution of Japanese is totally different, where we see a group of intermediate sounds, which is known as the Japanese R. So babies absorb the statistics of the language and it changes their brains; it changes them from the citizens of the world to the culture-bound listeners that we are. But we as adults are no longer absorbing those statistics. We're governed by the representations in memory that were formed early in development.
So what we're seeing here is changing our models of what the critical period is about. We're arguing from a mathematical standpoint that the learning of language material may slow down when our distributions stabilize. It's raising lots of questions about bilingual people. 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, 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.
(Video) Mandarin Speaker: [Mandarin]
PK: So what have we done to their little brains? (Laughter) We had to run a control group to make sure that just 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 non-invasive and silent. We're looking at millimeter accuracy with regard to spacial and millisecond accuracy using 306 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. She's a six-monther. 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. In investigating the child's brain, we're going to uncover deep truths about what it means to be human, and in the process, we may be able to help keep our own minds open to learning for our entire lives.
Thank you.
(Applause)
