左撇子更容易成为天才,惯用左手是好事
编辑点评:惯用右手好?还是惯用左手好?惯用右手可能更方便,但似乎惯用左手更容易聪明。
The belief that there is a link between talent and left-handedness has a long history. Leonardo da Vinci was left-handed. So were Mark Twain, Mozart, Marie Curie, Nicola Tesla and Aristotle. It&s no different today &&business leader Bill Gates&is a left-hander, as is &footballer Lionel Messi.天才和左撇子之间自古以来就有着某种联系。达芬奇、马克&图文、莫扎特、居里夫人、尼古拉&特拉斯、亚里士多德都是左撇子。直到现在这种联系依然屡见不鲜,商界领袖比尔&盖茨、足球运动员梅西都是左撇子。
But is it really true that left-handers are more likely to be geniuses? Let&s take a look at the latest evidence & including our new study on handedness and
ability.但是左撇子真的更容易成为天才吗?不妨来看看最新的调查:左右手偏向性实验与数学能力的关系。
Unsurprisingly, the role played by handedness in mathematics has long been a matter of interest. More than 30 years ago, a seminal study claimed left-handedness to be a predictor of mathematical precociousness. The study found that the rate of left-handedness among students talented in mathematics was much greater than among the general population.长期以来,左右手偏向性在数学中的作用备受瞩目。30多年前,一项重要实验表明,左手偏向性预示着数学能力提前发育。该试验发现,在擅长数学的学生中,使用左手的人数比例远大于不擅长数学的学生中使用左手的人数比例。
However, the idea that left-handedness is a predictor of superior intellectual ability has been challenged recently. Several scholars have claimed that left-handedness is not related to any advantage in cognitive skills, and may even exert detrimental effects on general cognitive function and, hence, academic achievement.但是日前,左撇子的智力发育更好这一说法面临挑战。一些学者认为,左手偏向性和认知技巧优势没有任何联系,左手偏向性甚至可能有损一般的认知能力,并因此妨碍获得学术成就。
For example, one study discovered that left-handed children slightly under-performed in a series of developmental measures. Also, a recent review reported that left-handers appear to be slightly over-represented among people with intellectual disabilities. Another large study found that left-handers performed more poorly in mathematical ability in a sample of children aged five to 14.比如有项实验发现惯用左手的儿童在种种发展性测试中表现欠佳。最近也有报告表示左撇子相较其他人更多地表现出了智力障碍。更有大型试验称,通过对5到14岁的儿童进行数学能力测试,发现其中惯用左手的孩子表现更加不如人意。
Left-handers seem to have, on average, an edge when solving demanding mathematical tasks & at least during primary school and high school. Also, being strongly right-handed may represent a disadvantage for mathematics. Taken together, these findings show that handedness, as an indicator of connectivity between brain hemispheres, does influence cognition to some extent.一般来说,左撇子可能在解决复杂数学问题上有些优势&&至少在小学和中学是这样。凡事都只使用右手可能不利于数学能力的发展。综合来看,左右手偏向性不但表明左右大脑半球互有连结,还在某种程度上影响着认知能力。
&That said, handedness is just an indirect expression of brain function. For example, only a third of the people with a more developed right hemisphere are left-handed. So plenty of right-handed people will have a similar brain structure as left-handers. Consequently, we need to be cautious in interpreting people&s hand preference & whether we see it as a sign of genius or a marker for cognitive impairment.这就说明左右手偏向性间接代表着大脑功能。比如只有三分之一的左撇子右脑发育更完全。所以很多右撇子和左撇子的大脑发育程度完全相同。这样一来,在定义不同的左右手偏向性是天才的象征还是认知障碍的外在表现时,我们就要谨慎一些。

左撇子,右撇子,到底谁更聪明?
作者:MedSci&&&来源: 中国生物技术网
但是左撇子真的更可能是天才吗?让我们来看一下最新的证据,关于用手习惯和数学能力之间的关系。据估计,人群中有10% 至13.5%的人不是惯用右手的,虽然这其中有一部分人可以“左右开弓”,但大部分的人还是只习惯用左手。用手偏好是大脑功能的一种表现形式,因此它与认知功能有关。平均来看,左撇子的大脑右半球更发达,右半球负责空间推理等过程以及旋转物体心理表征的能力。心理表征是认知心理学的核心概念之一,指信息或知识在心理活动中的表现和记载的方式。此外,左撇子的胼胝体(将大脑左右半球连接起来的神经细胞束)也更大。这表明,左撇子的左右半球连通性更好,因此在信息处理方面也更强。然而其中的原因尚不明确。一种理论认为,生活在一个为惯用右手的人设计的世界中迫使左撇子两手都要用,因此增强了脑半球之间的连通性。这就带来了这样一种可能性,即我们所有的人都可以通过双手并用训练来增强脑半球之间的连通性。这也许是左撇子在某些专业和艺术方面更有优势的原因。比如,在音乐家、有创造性的艺术家和象棋选手中,左撇子的比例非常高。不需多言,高效的信息处理和卓越的空间能力是取得这些成就的关键。用手习惯和数学能力但是惯用左手和数学能力之间的关系是怎么样的呢?人们对用手习惯对数学能力的影响一直很感兴趣。30年前,一项开创性研究声称,惯用左手能够预测数学能力。该研究发现,左撇子在数学天才的学生中的比例比远高于普通人群。胼胝体然而,左撇子能够预测卓越的智力这个观点最近受到了挑战。一些专家认为左撇子与认知能力优势之间没有关系,甚至可能对认知功能产生不利影响,因此影响学术成就。比如,一项研究发现,惯用左手的孩子在一系列发展测试中表现都不佳。此外,一篇最近的综述报告称,左撇子在智力残疾人群中的比例也比较高。另一项大型研究发现,在5至14岁的中,左撇子的数学能力更差一些。精心设计的实验有趣的是,过去的这些研究在评价用手偏好和将受测者分类方面都各不相同,某些研究只是简单地问一下受测者习惯用哪只手。最重要的是,它们评价数学能力的方法也不同,有的使用简单的算术,有的使用了复杂的数学问题。这些实验设计方面的差异可能是导致观察结果不同的原因。为了得到更可靠的结果,我们决定招募超过2300名学生(小学和高中)参与一系列实验。在这些实验中,数学任务的种类和难度都不相同。为了确保可比较性,我们使用相同的问卷(Edinburgh用手习惯调查)来评估用手习惯。这个问卷询问受测者偏好用哪只手写字、画画、扔东西、刷东西等。它能够评估一个人偏好用左手和用右手的程度,它是对用手习惯程度的衡量,而不是绝对地惯用左手还是右手。这可以帮助我们建立更可靠的统计模型。发表在《Frontiers》上的研究结果表明,当使用复杂数学问题时,左撇子的表现比其它人更好,比如将数学函数和数据集结合到一起。这种模式在男性青少年中尤为明显。相反,当数学任务不是那么难时,比如做简单算术,惯用哪只手并没有什么区别。我们还发现,极端的惯用右手者(他们做什么事情都喜欢用右手)相比于中等的惯用右手者和左撇子在所有的实验中表现都不佳。平均来看,左撇子在解决数学问题方面更有优势,至少是在小学和高中阶段。此外,非常强的惯用右手习惯或许代表了数学能力的劣势。总而言之,这项发现表明,指示大脑左右半球连通性的用手习惯确实在某种程度上会影响认知能力。也就是说,用手习惯只是大脑功能的一种间接表现。比如,只有三分之一大脑右半球更发达的人是左撇子。所以,很多惯用右手的人也有与左撇子类似的大脑结构。因此,在通过用手习惯来评价某人聪明或者愚笨时,我们必须要非常谨慎。

资料图 普通人中有90%的人都惯用右手
  ‘A “rightie” gesturing with his right hand appears on our bad side of TV. While a left-hander appears to be putting things in a much more positive light for the 90% of viewers who are right-handed.’
  “惯用右手的人在用右手打手势时从电视里看是在左边,传达的是消极信息;而‘左撇子’从观众角度看则像是在用右手,传达的是积极信息,而普通人中有90%的人都惯用右手。”

为什么有的人是左撇子?

在这个右撇子占绝对多数的世界,却有这样一群左撇子:他们之中天才辈出,他们对人类文明的贡献和对人类历史、生活的影响远远高于他们在人口中的比例。左撇子到底缘何而来?我们来看看科学家的解释。
&Because lefties do it right!&
&Because left handed people are the only people in their right minds?&
This question is definitely not a no-brainer.
Two theories predominate in the debates that rage on as to why a mere 4% of the population is left-handed. Most authorities agree, to the relief of many a mother of a left-handed child, that if the child prefers using the left hand, and functions well with it, there is no need to correct this &condition.&
One theory centers on the two halves of the brain, i.e. the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain predominates over the right half. The stem of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate. The end result is that the opposite sides of the body are supplied by the opposite sides of the brain.
The predominant left half of the brain, which graciously supplies the right half of the body, theoretically renders it more skillful in reading, writing, speaking, and working, and makes most people right-handed. &Lefties,& however, are the product of an inversion, whereas the right half of the brain predominates, and they work best with the left side of their bodies.
Theory number two trickles down to the asymmetrical nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left.
There is no doubt that all exist in a &right-handed society,& which manufactures most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instruments for the 96%. Left-handed people compensate for this snobbery of sorts, by being members of an elite society, which includes many of the greatest geniuses, including Michelangelo, Leonardo da Vinci, and The Useless-Infomaster.
reciprocate: 交叉,交互
