Abstract

The handedness distribution of a group of 578 gifted elementary school children (I.Q. = 132) was compared to handedness distribution of 391 non-gifted children (I.Q. less than 132), with the result that the gifted group was significantly less right-handed than their non-gifted peers. These data were discussed relative to Bakan's hypothesis that left-handedness results from stressful prenatal and birth conditions. In addition attention was paid to the possibility of a non-linear relationship between intelligence and degree of right-handedness.

摘要

对一组578名天才小学生（智商 = 132）的用手习惯分布与391名非天才儿童（智商低于132）的用手习惯分布进行了比较，结果发现，天才组的右利手程度明显低于他们的非天才同龄人。这些数据是相对于巴坎的假说进行讨论的，该假说认为左利手是由产前和出生时的压力状况导致的。此外，还关注了智力与右利手程度之间非线性关系的可能性。
