江苏汉族7项不对称行为特征的研究

对江苏省淮安市336例高中学生（男125例，女211例）抽样调查的汉族7项不对称行为特征（包括扣手、利手、叠臂、叠腿、利足、起步类型和优势眼）资料进行研究．研究结果显示：（1）除叠臂和起步类型外，其他5项指标右型率均高于左型率；（2）除叠臂和叠腿外，其他5项指标性别差异均不具有统计学意义；（3）与现已调查的国内其他族群比较发现，江苏汉族利足右型率（95．24％）处于高等水平，扣手右型率（54．46％）和利手右型率（94．64％）处于中等偏上水平，叠腿右型率（75．60％）处于中等水平，叠臂右型率（49．40％）处于中等偏下水平，起步类型右型率（37．80％）和优势眼右型率（62．50％）处于低等水平；（4）利足与利手、利足与叠腿这2对性状特征间相关性具有高度统计学意义，右型-右型率显著高于左型-左型率．

Studies of seven behavioral traits of lateral functional dominance of Han in Jiangsu

Seven behavioral traits of lateral functional dominance （clasping hand; handedness, folding arm, folding leg, preferential foot, stride type, preferential eye） were investigated in a sample of 336 high school students （125 males, 211 females） of Han in Huaian of Jiangsu. The results were as follows： （ 1 ） The percentage of the right type （R-type percentage） on the seven traits was higher than that of left type, except folding arm and stride type. （2） No significant sexual difference was found in the seven traits except folding arm and folding leg. （3） With regard to the R-type percentage, compared with other ethnic groups in China, it is found that preferential foot stands （95.24%） at the high level, clasping hand （54.46%） and handedness （94.64%） stand at the upper middle level, folding leg （75.60%） stands at the middle level, folding arm （49.40%） stands at the lower middle level, and stride type （37.80%） and preferential eye （62.50%） stand at the low level. （4） There is very significant correlation on the R-type percentage between preferential foot and handedness as well as between preferential foot and folding leg.
