研究：左撇子易患心理疾病
<p>《神经心理学》期刊发表的一篇最新研究发现，左撇子的人面临更多的心理健康问题，包括多动症、失读症，甚至精神分裂症。数据表明，左撇子的人和双手通用的人患心理疾病的概率高。他们占人口总数的比例分别为10%和1%，而可能患精神分裂症的比例却高达20%和30%。然而，《华尔街日报》也报道了一些好消息，比如左撇子的人有更好的发散思维和创造性。不仅如此，美国前任十届总统中，有六位都是左撇子，其中包括奥巴马和布什。截止目前，医生仍不能确定是什么原因导致用手的偏好，但发现环境因素，特别是子宫内的压力起着重要作用。例如，大龄产妇或体重轻的婴儿更容易是左撇子。人们常说左撇子的人使用右脑，用右手的人使用左脑，这种说不一定完全准确，但却可以解释为什么左撇子的人更容易遭遇心理障碍。</p><p><span word="New">New</span> <span word="research">research</span> <span word="published">published</span> <span word="in">in</span> <span word="the">the</span> <span word="journal">journal</span> <span word="Neuropsychologia">Neuropsychologia</span> <span word="finds">finds</span> <span word="that">that</span> <span word="left">left</span>-<span word="handed">handed</span> <span word="people">people</span> <span word="are">are</span> <span word="at">at</span> <span word="increased">increased</span> <span word="risk">risk</span> <span word="for">for</span> <span word="certain">certain</span> <span word="mental">mental</span> <span word="health">health</span> <span word="issues">issues</span>, <span word="including">including</span> <span word="ADHD">ADHD</span>, <span word="dyslexia">dyslexia</span> <span word="and">and</span> <span word="even">even</span> <span word="schizophrenia">schizophrenia</span>.</p><p><span word="For">For</span> <span word="example">example</span>, <span word="while">while</span> <span word="left">left</span>-<span word="handed">handed</span> <span word="people">people</span> <span word="make">make</span> <span word="up">up</span> <span word="only">only</span> 10 <span word="percent">percent</span> <span word="of">of</span> <span word="the">the</span> <span word="population">population</span>, 20 <span word="percent">percent</span> <span word="of">of</span> <span word="schizophrenics">schizophrenics</span> <span word="are">are</span> <span word="left">left</span>-<span word="handed">handed</span>. <span word="And">And</span> <span word="those">those</span> <span word="who">who</span> <span word="are">are</span> <span word="ambidextrous">ambidextrous</span> (<span word="able">able</span> <span word="to">to</span> <span word="use">use</span> <span word="both">both</span> <span word="hands">hands</span>), <span word="only">only</span> <span word="an">an</span> <span word="estimated">estimated</span> 1 <span word="percent">percent</span> <span word="of">of</span> <span word="the">the</span> <span word="total">total</span> <span word="population">population</span>, <span word="may">may</span> <span word="be">be</span> <span word="even">even</span> <span word="more">more</span> <span word="at">at</span> <span word="risk">risk</span>; 30 <span word="percent">percent</span> <span word="of">of</span> <span word="schizophrenics">schizophrenics</span> <span word="are">are</span> <span word="ambidextrous">ambidextrous</span>.</p>
