摘　　要：2009年12月调查了314例四川凉山彝族中学生的7项不对称行为特征(扣手、利手、叠臂、叠腿、利足、起步和优势眼).研究结果显示:1)彝族7项不对称行为特征的出现率右型均高于左型;2)彝族7项不对称行为特征的出现率利手、叠臂、叠腿、起步有显著的性别差异,其余3项指标的出现率均没有性别间差异;3)彝族与国内11个民族出现率的比较显示,彝族与汉族、朝鲜族、回族、布依族、苗族有显著差异,彝族7项不对称行为右型率在我国族群中属中等水平;4)分析了彝族7项指标间的相关性,发现利手与利足这对特征相关极显著,起步与利足这对特征相关显著.A sample of 314 middle school students of Yi in Sichuan Province was investigated on 7 kinds of behavioral traits of lateral functional dominance（hand clasping,handedness,arm folding,leg folding,foot preference,stride type and eye preference） in Dec.2009.The results are as follows.1）The percentage of the right type on 7 traits in Yi is much higher than that of left type.2）There is sexual difference on handedness,arm folding,leg folding and stride type while there is no sexual difference on the rest items.3）There is no obvious difference between Yi and other 11 nationalities in China on the percentage of left type on 7 traits,excluding Han,Chaoxian,Hui,Bouyei and Miao.The right type rates of behavioral traits of lateral functional dominance in Yi are middle level among the groups in China.4）Among the 7 traits,the correlations are prominent between handedness and foot preference,between stride type and foot preference.
