学习障碍儿童一般智力因素的研究

Studies of Gencral intelligence Factors in Learning Disahility thildren

采用瑞文测验联合型（ＣＲＴ）对学习障碍（ＬＤ）儿童和正常儿童进行了测试比较。结果：ＬＤ组在各单元测题上的得分均值及总体分数、ＩＱ值均低于对照组。经对测试结果作因子分析，发现各单元的测题均与一个独立的因素─—第１因素产生了较高的负荷（负荷值均在０．７以上）。表明ＬＤ组儿童一般智力能力存在缺陷，尤突出表现在类比推理及抽象概括能力上。也说明本研究结果有较理想的因素负荷效度。ＥＰＱ测试结果显示。两组儿童在各维度上的得分及换算的Ｔ值上均无显著性差异。

The authors had compared the general intelligcnce factors in normal children with those in learning disability childrcn(LDC). using tRT. The result was:the average scorcs in all test units ,the general score and the IQ of LDC were ltss than those of normal controls indicating there exists general intelligence ability defect in LDC especially in abilities of similarity. abstraction and generalization. Factor analysis was also performed and the result shnwed that all test units were wcll correlatctl to an independent factor that produced relatively high loading value (0. 7). There was no significant difference in the scorcs of various latitude and T value hetween the two groups.
