鄂伦春、鄂温克、达斡尔族一侧优势功能特征研究

报道了鄂伦春、鄂温克、达斡尔族7项一侧优势功能特征(扣手、利手、叠臂、叠腿、起步类型、优势足、优势眼)。结果显示,3个民族7项特征的左右型分布规律有较多的相似之处,绝大多数特征与性别无关。鄂温克族和达斡尔族的利手与叠腿、优势足、起步类型间均具明显关联,其腿足特征间的相关程度亦优于手臂特征。鄂伦春族则不然。 Abstract:Authors reported 7 traits of lateral functional dominance including hand clasping,handedness,arm folding,leg folding,stride type,foot preference and eye preference in Oroqen,Ewenki and Daur nationalities.The results showed as follws;(1)Among three nationalities their left and right distributive patterns of the traits had many similarities and there was no relation between most traits and sexes.(2)There were obvious corelations between handedness and leg folding,handedness and foot preference,handedness and stride type in Eweike and Daur nationalities.Compared with the traits of leg-foot with interrelation,the traits of hand-arm had little degree on correlation in Ewenki and Daur.(3)There was correlation between eye preference and hand clasping but no relation between handedness and hand clasping.
