内蒙古汉、回、蒙古族扣手、交叉臂及惯用手的分析

Analysis of Investigative Data for Hand-clasping,Arm-folding and Handedness in Han,Hui and Mongolian Ethnic Groups

利用对数线性模型分析了郑连斌、陆舜华等1996年在内蒙古调查的汉、回、蒙古族的3项人类遗传学指标(扣手、交叉臂、惯用手),得出与其既有相同又有不同的结论。结果显示:(1)扣手与民族、性别都无关;(2)交叉臂与民族不相关,与性别相关;(3)惯用手、民族、性别三者存在三因子效应;(4)惯用手与扣手、惯用手与交叉臂分别存在相关性,而交叉臂与扣手之间相关性不显著。

In this paper,authors recalculated the data of ZHENG Lianbin et al.in 1996(Handclasping,Armfolding and Handedness)by loglinear model.The results demonstrated both agreement and disagreement with the published data.The results show as follows:(1)There are no relations between handclasping and populations,sex;(2)There are obvious correlation between armfolding and sex,but no relation between armfolding and populations;(3)There are three factorial effects among handedness,populations and sex;(4)In our study,we found association between handedness and handclasping,armfolding and nonassociation between handclasping and armfolding.
