摘要
在上海浦东选取63例先天智障,101例正常偏低智商儿童,分析各项指掌纹参数和环指基纹的左右对称性,分析各项肤纹参数与智商的相关性,尝试总结各种肤纹参数与先天智障的相关性,分析肤纹的均衡性和对称性与智商的关系,在上海人群中验证文献总结的智商与肤纹的相关规律.发现先天智障儿的十指嵴纹数明显趋于均衡,双手略趋对称.拇指环指嵴纹数和指端嵴纹总数,左手指间三区嵴纹数均与智商极显著正相关,atd角,左手环指基纹偏度与智商极显著负相关.人类的智慧可能是与均衡性及对称性的破缺引起的人体局部特异性变化有关,先天智障可能是这种均衡破缺机制失效引起的,同时反映于肤纹和智力.
The relationship between dermatoglyphic parameters and constitutional mental retardation was explored by correlating the IQ and equipoise and zygomorphism of dermatoglyphy in a Shanghai population. Sixtythree constitutional retarded children and 101 agematched normal controls with low IQ are collected. The relationship of IQs and the dermatoglyphy on palms and fingers, the leftright symmetry of ringer finger basal patterns was studied. Ten fingers' ridge counts between constitutional retarded children are more balanced, while their patterns on left and right hands are more symmetrical than their counterparts. Among all the traits examined, the IQ is positively correlated with the thumb, ringer finger FRC, TFRC, RC of interdigital pattern Ⅲ of left hand, and negatively correlated with ∠atd, degree of deviation on ringer finger basal pattern. The observations made in this study contradict previous ones and hypothesis was founded that the development of human intelligence is a process of differentiation which could be reflected loss of equipoise (LOE) and loss of zygomorphism (LOZ).
