学习困难儿童智力亚型的研究

以ＷＩＳＣ－ＣＲ１１个分测验量表分为变量对１０３名学习困难及与之配对的学业良好儿童进行聚类分析。结果显示，两组儿童均聚为３个智力亚型。学习困难儿童第１型ＦＩＱ中等偏上，与对照组第２型相当，但常识和译码分测验量表分低；第２型ＦＩＱ中等偏下，ＶＩＱ显著落后ＰＩＱ，该型ＰＩＱ与对照组第３型相等，但译码量表分显著低于对照组；第３型属边缘智能，算术分测验成绩更差。结果提示，学习困难儿童存在不同的智力亚型，表现为智力水平不等和智力结构方面的缺陷。

Study on intelligence subtypes for children with learning disorders

The intelligence of 103 children with learning dirorders (LD) and 103 age-sex-matched excellent ones were measured by the Wechsler Intelligence Scales for Children-Chinese Revision (WISC-CR). The controls were divided into three subtypes by cluster analysis, based on the WISC-CR profile. The children with LD were also divided into three subtypes. In the First subtype, the scores of Information and Coding of children with LD were lower than that of the controls in the secondary subtype. The children in subtype 2 (mean Full IQs=92. 5)got poorer scores for concentration and memory, compared with the controls in the third suptype. Children's intelligence was on borderline state in the third subtype and displayed a lower scale score of Arithmetic. It is revealed that children with LD are characterized by a low IQs and deficiency in some intelligence factors.
