基诺族的不对称行为特征与舌运动类型

Behavioral traits of lateral functional dominance and tongue moving types in Jino

应用人体测量方法,赴云南省西双版纳傣族自治州景洪市基诺族乡对600例(男279例,女321例)基诺族人的扣手、利手、叠臂、卷舌、尖舌和翻舌进行调查.结果表明,基诺族的扣手右型率为55.50%,利手右型率为96.50%,叠臂右型率为38.67%,性别间差异无统计学意义(P>0.05);卷舌率为47.67%,尖舌率为46.00%,翻舌率为5.00%,仅卷舌率的性别间差异具有高度统计学意义(P<0.01).与中国西南地区的13个族群进行比较,基诺族的利手右型率处于较高水平,扣手和叠臂右型率处于偏低或较低水平;卷舌率、尖舌率和翻舌率均处于较低或极低水平.基于不对称行为和舌运动类型的聚类分析结果表明,基诺族与云南布朗族的亲缘关系最接近.

Using anthropometric methods, a sample of 600 Jino people （male 279, female 321 ） was investigated in Jino township of Jinghong City of Xishuangbanna Dai Autonomous Prefecture in Yunan Province. The behavioral traits of lateral functional dominance included clasping hand, handedness, folding arm; the tongue moving types included tongue rolling, pointed tongue and tongue twisting. The results showed that the frequencies of right type of clasping hand, handedness and folding arm were 55.50%, 96.50% and 38.67% respectively, and there were no sexual statistic differences for the three traits （P〉 0.05）. The percentages of tongue rolling, pointed tongue and tongue twisting were 47.67%, 46.00% and 5.00% respectively, and only tongue rolling had highly sexual statistic difference （P 〈 0.01 ）. Compared with 13 ethnic groups in the southwest of China, the frequency of right type of handedness was in a high level, and the frequencies of the other two traits were in slightly lower or rather lower level. Tile three types of tongue moving types were all in rather lower or extremely lower levels. According to the cluster analysis based on the three traits of lateral functional dominance and three tongue moving types indicated that Jino had the closet relationship with Blang in Sichuan Province.
