测谎研究—你真的能识别孩子的谎言么？

关于孩子爱撒谎，那些大人们还不知道的事。

演讲者

孩子们都会说谎吗？成人能轻易发现他们的谎言吗？发育研究者Kang Lee说，其实孩子们从2岁就开始说谎了，而且他们还很擅长，谎言并不易被辨识。为此他提出新的测谎技术。演讲以研究儿童撒谎为主线分析了撒谎者复杂的心里机制（读心与伪装能力），并提供新视角让人类深度了解自身，同时可利用测谎技术服务于更多社会领域。

With an international team based at the University of Toronto, Kang Lee investigates the neurological and social basis of emerging social behaviors in young children. His two-pronged research focuses first on how and when children develop the capacity to lie, to detect lies and to feel guilty about it afterward. The second focus of Lee's research is facial recognition, which has led to revelations of when children develop the ability to distinguish races.

李康在多伦多大学国际团队的协助下做了一个研究：幼儿在神经学和社会学的基准上如何形成自身的社会行为。研究分为两个方向，一个是幼儿是什么时间段，如何学会撒谎，以及撒谎过后的愧疚感。另一个方向是面部识别，此方向引导并启发了对于儿童何时开始发展自我认知的研究。

So for the last 20 years, I've been studying how children learn to tell lies. And today, I'm going to share with you some of the discoveries we have made. Three common beliefs we have about children and lying: One, children only come to tell lies after entering elementary school. Two, children are poor liars. We adults can easily detect their lies. And three, if children lie at a very young age, there must be some character flaws with them, and they are going to become pathological liars for life. Well, it turns out all of the three beliefs are wrong.

在过去的二十年，我一直在研究孩子们如何学会撒谎。今天我将与给分享我们的一些成果。很好的总结了三个我们对于孩子撒谎的常识。第一，孩子通常在上小学后开始撒谎。第二，孩子不会撒谎成人可以简单地识破他们。第三，如果孩子很早就开始撒谎那么他们一定有一些人格缺陷，并且一生都将是病态的撒谎者。然而结果是，这三个认识都是错的

Vocabulary:

Detect [dɪˈtɛkt] 查明，发现;洞察;侦察，侦查;[电子学]检波

Flaw [flɔ] 瑕疵，缺点;一阵狂风;短暂的风暴;裂缝，裂纹

Pathological [ˌpæθəˈlɑ:dʒɪkl] [医]病理学的;由疾病引起的;病态的，疾病的

We have been playing guessing games with children all over the world. But in the middle of the game, we make an excuse and leave the room. Because the desire to win the game is so strong, more than 90 percent of children will peek as soon as we leave the room. We found that regardless of gender, country, religion, after four years of age, most children lie. So as you can see, lying is really a typical part of development. And some children begin to tell lies as young as two years of age.

我们一直和全世界的孩子们一起玩竞猜游戏。在游戏的中间，我们会借故离开。因为孩子太想赢这个游戏，超过90%的孩子在我们离开后马上偷偷看了卡片。我们发现无论性别国籍宗教信仰，大于四岁的孩子绝大部分都在撒谎。如您所见，撒谎是成长典型的一部分。很多孩子在2岁的时候就已经学会了撒谎。

Vocabulary:

Peek [pik] 偷看，窥视;眯着眼睛看

Regardless [rɪˈgɑ:rdləs] 不顾后果地;不管怎样，无论如何;不惜费用地

So now, let's take a closer look at the younger children. Why do some but not all young children lie? The first key ingredient is theory of mind, or the mind-reading ability. Mind reading is important for lying because the basis of lying is that I know you don't know what I know. Therefore, I can lie to you. The second key ingredient for good lying is self-control. It is the ability to control your speech, your facial expression and your body language, so that you can tell a convincing lie.

现在我们仔细研究小孩子。为什么不是所有的孩子都撒谎？第一个是心智理论，换言之读心的能力。读心能力在撒谎时很重要因为撒谎从根本上说就是我知道你不知道我知道。因此我的谎言成功了。第二个撒谎的关键因素是自我控制控制语言控制面部表情控制身体动作。这样的谎言才让人信服。

Vocabulary:

Ingredient [ɪnˈgri:diənt] 因素;（混合物的）组成部分;（烹调的）原料;（构成）要素

Facial [ˈfeʃəl] 面部的;面部用的;表面的

Convincing [kənˈvɪnsɪŋ] 有说服力的;令人相信的;令人心悦诚服的

And we found that those young children who have more advanced mind-reading and self-control abilities tell lies earlier and are more sophisticated liars. As it turns out, these two abilities are also essential for all of us to function well in our society. In fact, deficits in mind-reading and self-control abilities are associated with serious developmental problems, such as ADHD and autism. So if you discover your two-year-old is telling his or her first lie, instead of being alarmed, you should celebrate —because it signals that your child has arrived at a new milestone of typical development.

我们发现那些小孩子中读心能力和自我控制能力更强的更早开始说谎也成为了更老练的撒谎者。事实证明这两种能力在社会中也是至关重要的。并且读心能力和自我控制能力不足经常和一些严重的发展问题比如多动症和自闭症联系在一起。所以当你发现你二岁的孩子开始撒谎不要惊慌你应该庆幸——因为这意味着你的孩子进入了典型发展的新的里程碑。

Vocabulary:

Sophisticated [səˈfɪstɪˌketɪd] 复杂的;精致的;富有经验的;深奥微妙的

Deficit [ˈdɛfɪsɪt] 赤字;亏损;亏空;不足额

be associated with 和…联系在一起;与…有关

ADHD 注意缺陷多动障碍，小儿多动症

Autism [ˈɔˌtɪzəm] 孤独症，自我中心主义

Signal [ˈsɪɡnəl] 信号，暗号;预兆，征象;动机;导火线

So when children lie, their facial expression is typically neutral. However, behind this neutral expression, the child is actually experiencing a lot of emotions, such as fear, guilt, shame and maybe a little bit of liar's delight. Unfortunately, such emotions are either fleeting or hidden. Therefore, it's mostly invisible to us. So in the last five years, we have been trying to figure out a way to reveal these hidden emotions.

所以孩子撒谎是他们的面部表情是很自然的。然而在自然的表情背后孩子在体验一系列的感情有害怕，内疚，羞耻也许还有一点骗人的喜悦。可是这些表情或一闪而过或被隐藏的很好，对于我们来说很难捕捉。所以过去的五年中我们一直在寻找挖掘隐藏的表情的办法。

Vocabulary:

Neutral [ˈnu:trəl] 中立的;（化学中）中性的;暗淡的;不带电的

Guilt [ɡɪlt] 有罪，犯罪行为，罪恶;[法律] 轻罪，过失;内疚，知罪;自责

Fleeting [ˈflitɪŋ] 短暂的;稍纵即逝;疾驰的，飞逝的;翩

Invisible [ɪnˈvɪzəbəl] 看不见的;不易为视线所见的，隐匿的;无形的（指银行、旅游等服务）;不引人注目的

Reveal [rɪˈvil] 揭露;泄露;显露;[神]启示

Then we made a discovery. We know that underneath our facial skin, there's a rich network of blood vessels. When we experience different emotions, our facial blood flow changes subtly. So to help us reveal people's facial emotions, we have developed a new imaging technology we call "transdermal optical imaging."

后来我们有了发现。我们知道在脸的皮肤下面是丰富的血管网络。在我们经历不同的情感的时候，我们面部血液流动也会稍微改变。我们可以发现人们隐藏的表情。所以我们设计了新的图像技术来帮助我们捕捉人们的面部表情。我们叫它“透皮光学成像”。

Vocabulary:

Subtly ['sʌtlɪ] 隐隐约约地

Transdermal [t'rænzdɜ:məl]（药物等）经皮吸收的，经皮给药的

Optical [ˈɑ:ptɪkl] 光学的;视觉的，视力的;眼睛的

optical imaging 光学成象

Of course, lying is not the only situation that will evoke our hidden emotions. So then we asked ourselves, in addition to detecting lies, how can our technology be used? One application is in education. And also we can use this in health care. We can also use this in marketing research. We can even use it in dating. So transdermal optical imaging technology is at a very early stage of development. Many new applications will come about that we don't know today. However, one thing I know for sure is that lying will never be the same again.

当然撒谎并不是激发隐藏表情的唯一情况。所以我们思考，除了测试谎言之外，这项技术还可以用来做什么？在教育领域可以应用这门技术。这门技术同时可以用在健康护理上；这项技术也可以用于市场调查；我们甚至可以用在约会上。所以透皮光学成像技术仅仅处于起步阶段。将来会有更多意想不到的新应用出现。然而我坚信研究谎言的未来将会因此变得不同。

Vocabulary:

Evoke: [ɪˈvoʊk] 唤起;产生，引起
