title: Learning disability in adults: a comparison of two indices of differential cognitive impairment derived from the Wechsler scales.
abstract: 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.
