婴儿的语言天赋
The Linguistic Gift of Babies
大家早上好。在今天的课上，我要讲一些你们看不到的东西。也就是：婴儿的大脑里是如何运转的。
Good morning, everyone. In today's lecture, I'm going to talk about something you can't e. That is, what's going on in the little brain of a baby.
例如，婴儿如何学习一门语言。
For example, how babies learn a language.
这是一个大家很感兴趣的问题。
It is always a question people show great interest in.
婴儿和七岁之前的儿童都是天才，七岁后就会出现系统性的衰退。
黑天鹅效应Babies and children are genius until they turn ven, and then there's a systematic decline.
我的实验室里工作的重点就是发育的第一个关键时期，在这个关键时期，婴儿试图掌握在他们的语言中用到的音。
Work in my lab is focud on the first critical period in development, and that is the period in which babies try to master which sounds are ud in their language.
我们认为，通过研究声音是如何习得的，我们将建立一个适用于语言其他方面的模型，也可能适用于儿童时期可能存在的社交、情感和认知发展关键时期的模型。
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.
所以我们一直在通过实验来研究这些婴儿。
So we've been studying the babies by conducting an experiment.
在我们的实验中，婴儿，通常是6个月大的婴儿，坐在父母的膝盖上，我们训练他们当音变化的时候转过头去，比如从“啊”变成“咿”的时候。
During our experiment, the baby, usually a six-months, sits on a parent's lap, and we train them to turn their heads when a sound changes—like from "ah" to "ee".
如果他们在正确的时候这样做，黑盒子就会亮起来，熊猫就会敲鼓。我们学到了什么?
If they do so at the appropriate time, the black box lights up and a panda bear pounds a drum. What have we learned?
全世界的婴儿就是我所说的“世界公民”。
Well, babies all over the world are what I like to describe as "citizens of the world".
