赤ちゃんの耳はいつから母国語になれる?Culture Bound Listener

先週ハナハウスで、赤ちゃんのバイリンガル脳についてのTEDTalkの講演のことを話しました。いつから耳が母語に慣れてしまうのか?日本語だけを聞いてる赤ちゃんは、英語のraとlaの違いを1歳前には聞きとることができなくなるそうです。

I've really come to enjoy the TED homepage which compiles lessons/lectures from various experts on many interesting topics.  Recently this talk from Patricia Kuhl was brought to my attention.  It speaks directly to what I do in teaching babies/moms signing in English.



The thing that I found the most interesting is the research that shows babies become culture bound listeners by age 1.  This means they stop hearing words/sounds that are not in their native language(s) by their first birthday.  I thought they had up will age 3... 1 is so early!
As I learned Japanese as an adult I have been able to learn to hear a few sounds that I wasn't able to when I first came to Japan however I still can't hear the difference between yu and ryu or byoin and byouin.  Thanks to this research I can understand that the reason is because my parents didn't have me take Japanese lessons with a native speaker when I was a baby.  Wonder if there was even a Japanese speaker in the area way back then...???

Another thing that caught my attention is the importance of hearing the language spoke by a person, not simply watching TV or listening to a CD.  This is a great reason to take a mommy & me style class!
