TED演讲:“短期记忆”如何理解世界
来源:TED    日期: 2014-01-02

    I'm going to give you five words, and I just want you to hang on to them. Don't write them down. Just hang on to them. Five words. While you're hanging on to them, I'm going to ask you to answer three questions. I want to see what happens with those words. So here's the words: tree, highway, mirror, Saturn and electrode. So far so good? Okay. What I want you to do is I want you to tell me what the answer is to 23 times eight. Just shout it out. (Mumbling) (Laughter) In fact it's -- (Mumbling) -- exactly. (Laughter) All right. I want you to take out your left hand and I want you to go, "One, two, three, four, five, six, seven, eight, nine, 10." It's a neurological test, just in case you were wondering. All right, now what I want you to do is to recite the last five letters of the English alphabet backwards. You should have started with Z. (Laughter)

    All right. How many people here are still pretty sure you've got all five words? Okay. Typically we end up with about less than half, right, which is normal. There will be a range. Some people can hang on to five. Some people can hang on to 10. Some will be down to two or three.

    What we know is this is really important to the way we function, right? And it's going to be really important here at TED because you're going to be exposed to so many different ideas.

    Now the problem that we have is that life comes at us, and it comes at us very quickly, and what we need to do is to take that amorphous flow of experience and somehow extract meaning from it with a working memory that's about the size of a pea. Now don't get me wrong, working memory is awesome. Working memory allows us to investigate our current experience as we move forward. It allows us to make sense of the world around us. But it does have certain limits.
