And there's been a bunch of interesting studies recently that have shown this playing around is really a kind of experimental research program.
最近有很多有意思的研究顯示了孩子的隨意嘗試，的確可以作為一個研究項目。
Here's one from Cristine Legare's lab. What Cristine did was use our Blicket Detectors.
這是克里斯汀·勒加雷的一項實驗。克里斯汀使用了我們的玩具偵探儀器。
And what she did was show children that yellow ones made it go and red ones didn't, and then she showed them an anomaly.
她向孩子展示黃色才能啟動儀器，紅色不行，然后又向孩子們展示了一個奇怪現(xiàn)象。
And what you'll see is that this little boy will go through five hypotheses in the space of two minutes.
你等一下就可以看到這個小男孩會在兩分鐘內(nèi)測試五個假設(shè)。
(Video) How about this? Same as the other side.
（視頻) 這個怎么樣？這邊也一樣。
Okay, so his first hypothesis has just been falsified.
所以他的第一個假設(shè)已經(jīng)被否認(rèn)了。
This one lighted up, and this one nothing. Okay, he's got his experimental notebook out.
這個亮了，這個沒有。看到?jīng)]有，他開始記筆記了。
What's making this light up. I don't know.
這盞燈為什么亮呢。我不知道。
Every scientist will recognize that expression of despair.
科學(xué)家們都見過這種絕望的表情。
Oh, it's because this needs to be like this, and this needs to be like this.
我知道了。這個要這樣，然后這個是這樣。
Okay, hypothesis two. That's why. Oh.
第二個假設(shè)。我知道了。哦。
Now this is his next idea. He told the experimenter to do this, to try putting it out onto the other location. Not working either.
他有了第三個想法。他告訴實驗者這樣做，試著把它放在一邊。還是不行
Oh, because the light goes only to here, not here. Oh, the bottom of this box has electricity in here, but this doesn't have electricity.
啊，因為只有這里會亮，這里不會。盒子下面呢，這里有電，但這邊沒電。
Okay, that's a fourth hypothesis.
他的第四個假設(shè)。
It's lighting up. So when you put four. So you put four on this one to make it light up and two on this one to make it light up.
亮了。你要在上面放四個。你在這上面擺四個，這上面擺兩個。
Okay,there's his fifth hypothesis.
測試他的第五個假設(shè)。
Now that is a particularly -- that is a particularly adorable and articulate little boy, but what Cristine discovered is this is actually quite typical.
這個小男孩—— 特別可愛，說話也很清楚，但是克里斯汀的發(fā)現(xiàn)其實很正常。
If you look at the way children play, when you ask them to explain something, what they really do is do a series of experiments.
如果你在小孩玩的時候觀察他們，或是要他們回答某個問題，他們會做一系列的嘗試。
This is actually pretty typical of four year-olds.
這對于四歲的兒童來說很普遍。
