左撇子有何特色?有人認為他們比較富創意,但是究竟他們的腦組織和智力,與一般人有沒有差異?答案是沒有,不過某些類型的人,似乎左撇子較多。

1某些運動員。從事某些運動,左撇子可能占些優勢。最佳的棒球投手和
男性網球選手,有兩成是左撇子。(整個人口比例中,約10%到12%的人是左撇子。另一
方面,男性左撇子也比女性來得多)

2某些性取向有差異的人。出現性認同疾病的人,左撇子比率較高。2001
年心理學公報刊出的研究發現,同性戀者左撇子較多,特別是女同性戀者。

3罹患某些自體免疫疾病的人。有項研究顯示,左撇子較易得氣喘、大腸
炎和腸躁症,不過研究還有爭議。另外,過去一直都認為,左撇子較短命,也較易受
傷。不過最近研究證實,情況並非如此。

4特殊和富創意的人。藝術家、建築師和西洋棋大師,較可能是左撇子。
另外,左撇子較易有語言方面的學習障礙。

5有精神疾病的人。精神分裂症的病人,比一般人較易用雙手作事。自閉
症的人左撇子較多。
