【摘要】 本工作对１２０例遗传型智残者和６０例非遗传型智残者的指、掌皮肤嵴纹数进行分析，并分别与相同例数的对照组同类资料进行比较，找出与智力发育相关的指端、指间区、指基部皮纹参数，据此将遗传型智残组按智商值的不同分为６个组，将不同智商组对应的各区嵴纹数进行分析处理。结果表明，指端皮肤嵴纹数与智商呈正相关，相关系数ｒ＝０．８３１９，各指间区和指基部嵴纹数与智商值呈负相关，相关系数ｒ＝－０．７３９２。更多还原

【Abstract】 Digital and palmar of 120 cases of hereditary mental deficiency and 60 cases of non-hereditary mental deficiency were analysed, and compared with the control group using the same cases and identical data, and then skin vein parameter interrelated with intelligence development for digital end, interdigital area, digital root were found. In the light of this we divided the hereditary mental deficiency group into 6 accorcding to IQ value, and analysed statistically every area ridge count corresponding to different IQ group. The result showed that ridge count of digital end was positively correlated with IQ value correlative coefficient r =0.8319; Whereas ridge count of interdigital area and digital root were negatively correlated with IQ value correlative cofficient r =0.7392.更多还原
