1、撞上快乐的作者丹吉尔伯特挑战不快乐是因为我们没有得到我们想要的东西的观点。我们的心理免疫系统能让我们感到正真的快乐，就算是事情并不如我们所愿。下面是为大家收集关于TED英语演讲我们为什么快乐，欢迎借鉴参考。演说题目我们为什么快乐演说者丹吉尔伯特When you have 21 minutes to speak,two million years seems like a really long time.But evolutionarily,two million years is nothing.And yet in two million years,the human brain has
2、 nearly tripled in mass,going from the one-and-a-quarter pound brain of our ancestor here, Habilis,to the almost three-pound meatloafthat everybody here has between their ears.What is it about a big brainthat nature was so eager for every one of us to have one相对二十一分钟的演讲来说，两百万年显得非常漫长。但是从进化的角度来看，两百万年只
3、是一瞬间。在两百万年中，大脑脑容量从我们祖先能人的25磅，增大了近三倍成了现在的3磅。自然给予我们的大脑有什么特别之处呢Well, it turns out when brains triple in size,they dont just get three times bigger;they gain new structures.And one of the main reasons our brain got so big is because it got a new part,called the frontal lobe.Particularly, a part called t
4、he pre-frontal cortex.What does a pre-frontal cortex do for you that should justifythe entire architectural overhaul of the human skullin the blink of evolutionary time当我们的脑量扩大三倍的时候，大脑不仅仅在体积上有了改变，它在结构上也发生了变化。我们大脑变大的最大原因就是它有了新的一部分，叫做额叶。其中尤为重要的是前额叶外皮。是什么让前额叶外皮成人脑中如此重要的一部分It turns out the pre-frontal c
5、ortex does lots of things,but one of the most important things it does is an experience simulator.Pilots practice in flight simulatorsso that they dont make real mistakes in planes.Human beings have this marvelous adaptationthat they can actually have experiences in their hea党史before they try them o
6、ut in real life.This is a trick that none of our ancestors could do,and that no other animal can do quite like we can.Its a marvelous adaptation.Its up there with opposable thumbs and standing upright and languageas one of the things that got our species out of the treesand into the shopping mall.脑前
7、额叶外皮有很多功能，其中最重要的是它拥有一种创造模拟经验的功能。飞行员利用在飞行模拟器中的训练来防止在真实飞行中产生失误。人类有惊人的适应性，他们可以在大脑中体验未曾真实经历的东西。这个技巧是我们的祖先们都不会的，也没有任何动物会。 这种适应性真不可思议!这一特征和对生拇指，直立行走以及语言使我们从树上进化到了购物中心。(Laughter)(笑声)All of you have done this.Ben and Jerrys doesnt have liver-and-onion ice cream,and its not because they whipped some up, trie
8、d it and went, Yuck.Its because, without leaving your armchair,you can simulate that flavor and say yuck before you make it.现在-我们大家都能做这些。我的意思是，比如本和杰瑞(一个冰激凌连锁店)没有肝和洋葱口味的冰激淋。并不是因为他们试做了一下，尝了尝，而后Yuck (表示恶心)。而是因为你坐在椅子上就可以想象肝和洋葱的口味的冰激淋是怎样恶心了。Lets see how your experience simulators are working.Lets just ru
9、n a quick diagnosticbefore I proceed with the rest of the talk.Heres two different futures that I invite you to contemplate.You can try to simulate them and tell me which one you think you might prefer.One of them is winning the lottery. This is about 314 million dollars.And the other is becoming pa
10、raplegic.让我们来看看经验模拟器是如何工作的。在我继续我的演说之前让我们来做一个简短的试验。这里有两个不同的未来，我想邀请你们一起来参与。你可以幻想这两种未来，看看你更喜欢哪一种。第一种未来是赢了价值14亿美元的彩票。第二种是截瘫。(Laughter)(笑声)Just give it a moment of thought.You probably dont feel like you need a moment of thought.我给你们几分钟考虑一下。你也许觉得根本不用考虑。Interestingly, there are data on these two groups of
11、 people,data on how happy they are.And this is exactly what you expected, isnt itBut these arent the data.I made these up!这里有一些很有趣的数据。这些数据显示了这两组人到底有多快乐。是不是这正如你们所料可其实这是我胡诌的数据。These are the data.You failed the pop quiz, and youre hardly five minutes into the lecture.Because the fact is that a year aft
12、er losing the use of their legs,and a year after winning the lotto,lottery winners and paraplegicsare equally happy with their lives.这才是真正的数据。你们都没有通过突击测试。这堂课开始还不到5分钟呢。事实是，在失去双腿一年之后，和在赢了彩票一年之后，中彩票的人和截瘫患者的快乐程度几乎相同。Dont feel too bad about failing the first pop quiz,because everybody fails all of the po
13、p quizzes all of the time.The research that my laboratory has been doing,that economists and psychologists around the country have been doing,has revealed something really quite startling to us,something we call the impact bias,which is the tendency for the simulator to work badly.For the simulator
14、to make you believe that different outcomesare more different than in fact they really are.现在，不要为没有通过突击测试而沮丧了。因为几乎没有人能通过这项突击测试。我实验室所做的研究，还有全国的经济学家和心理学家所做的研究显示了一种让人吃惊的东西。我们称它为影响偏差。这是指人脑的模拟功能有犯错误的倾向。模拟器会夸大事物的不同结果而这些结果实际上未必有多么的不同。From field studies to laboratory studies,we see that winning or losing an
15、 election,gaining or losing a romantic partner,getting or not getting a promotion,passing or not passing a college test,on and on, have far less impact,less intensity and much less durationthan people expect them to have.This almost floors me -a recent study showing how major life traumas affect peo
16、plesuggests that if it happened over three months ago,with only a few exceptions,it has no impact whatsoever on your happiness.现场研究和实验室研究都显示选举的输赢，伴侣的得失，提升与否，考试成败等等，对我们的影响及影响的时间长短都比人们想象的少。事实上，最新的研究几乎让我都迷惑了。最新的研究显示，发生在三个月以前的重大的创伤，除了少数个别例子对你今日的快乐几乎没有影响。WhyBecause happiness can be synthesized.Sir Thomas Brown wrote in 1642, I am the h
