[目的]了解仫佬族7项不对称行为特征。[方法]采取随机整群抽样法,调查仫佬族309例中学生(男120例,女189例)7项不对称行为。[结果](1)7项指标在仫佬族中的出现率R型远高于L型;(2)仫佬族7项不对称行为特征的出现率均无性别间差异;(3)与国内8个其他民族L型率的比较显示,发现仫佬族与汉族、蒙古族,朝鲜族有统计学差异。(4)分析了仫佬族7项指标间的相关性,发现扣手与利足,扣手与利手,起步与叠腿,起步与利足,叠腿与利足,利眼与利臂间存在相关性,且R-R组合(右型-右型)的出现率远高于L-L型组合(左型-左型)的出现率。[结论]仫佬族7项不对称行为特征及其相关性与别的民族相比有相似之处,也存在很多不同的特点。
[Objective] To understand the characteristics of 7 asymmetric behaviors among Mulam people. [Methods] A random cluster sampling method was used to investigate 7 asymmetric behaviors among 309 middle-school students (120 males and 189 females) of Mulao ethnic group. [Results] (1) The incidence of 7 indicators in Mulao ethnic group was much higher than that of L type group. (2) There was no gender difference in the incidence of 7 asymmetric behavior among Mulam people. (3) A comparison of L-rate among 8 other nationalities in China shows that there are significant differences between Mulam and Han, Mongolian and Korean nationalities. (4) The correlation between 7 indicators of Mulam was analyzed. It was found that there were 7 kinds of indicators in Mulam, including hand and foot, hand and hand, starting and folding, starting and supporting, legs and legs, There was a correlation between the RR combinations (right-right type) and the incidence of LL type combinations (left-left type). [Conclusions] There are many similarities between the characteristics and their correlations of 7 asymmetric behaviors among Mulam ethnic groups and other ethnic groups.
