Two indices descriptive of patterns of differential cognitive impairment have been derived from principal component analyses of the normative data of the Wechsler scales for adults (WAIS-R) and children (WISC-R), respectively. The former index is sensitive to the test-specific cognitive effects of unilateral cerebral damage in adults. The latter accurately describes the pattern of subtest scores produced by learning-disabled children. The present study reviews the available WAIS and WAIS-R data from adults with learning disability in order to determine which of these two indices more precisely delineates their pattern of test performance; the index derived from the children's test appears to be the one best able to do so.
分别从韦氏成人智力量表（WAIS-R）和韦氏儿童智力量表（WISC-R）的常模数据的主成分分析中得出了两个描述差异性认知障碍模式的指标。前一个指标对成人单侧脑损伤的特定测试认知效应敏感。后一个指标准确地描述了学习障碍儿童产生的子测试分数模式。本研究回顾了来自有学习障碍的成人的现有WAIS和WAIS-R数据，以确定这两个指标中的哪一个能更精确地描绘他们的测试表现模式；从儿童测试中得出的指标似乎是最能做到这一点的。
