There are few tests that assess reading comprehension in adults, but these tests are needed for a comprehensive assessment of reading disorders (RD). "The Nelson-Denny Reading Test" (NDRT) has a long-passage reading comprehension component that can be used with adolescents and adults. A problem with the NDRT is that reading comprehension…

A learning disability index (LDI) based on a principal components analysis of the Weschler Intelligence Scale for Children-Revised normative data has been developed to depict verbal or nonverbal deficits on that test. Ss (N=1550) referred for educational difficulties returned mean scores on the LDI that were reliably different from expected scores…

Evaluated was whether factor analysis of the 12 Illinois Test of Psycholinguistic Abilities subtest scores earned by 90 underachieving children (between 5 and 10 years of age) would support the dimensions of psycholinguistic processes, organizational levels, and communication channels as described in the clinical model of the instrument.

The practice of evaluating certain special education tests in terms of traditional test evaluation procedures appears inconsistent with observations that these tests are often so closely tied to instructional procedures that they are not separable in practice. (Author)

The study examined correlations between the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test-Revised (PPVT-R), and the Kaufman Assessment Battery for Children (K-ABC) for 44 learning disabled primary and intermediate special class students. The Mental Processing and Achievement scales of K-ABC…

The study was designed to determine not only the comparability of the Wechsler Intelligence Scale for Children (WISC) and the WISC-Revised (WISC-R) with 40 minimal brain dysfunction children (6-10 years old), but also to determine whether well-established, clinically useful configurations emerge in the WISC-R as they do in the WISC.

In this study, we examined the characteristics of reading disability (RD) in the seventh grade of the Greek educational system and the corresponding diagnostic practice. We presented a clinically administered assessment battery, composed of typically employed tasks, and a fully automated, computer-based assessment battery that evaluates some of…

The paper evaluates the empirical and theoretical basis upon which several recent studies reject the hypothesis of a visual-perceptual deficit in reading disabilities. (Author)

The Learning Disability Index (LDI) was validated by an examination for mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum was found to measure Third Factor strengths/weaknesses as much as verbal-performance…

The study involving 371 first graders in the initial sample and 206 in the follow-up evaluated the reliability and validity of the Matching Familiar Figures Test for its possible use in diagnosing the learning problems of young children, who may need special educational services. (Author/SBH)

Two methodological problems often arising in dyslexia research are considered. The first problem concerns the validity of experimental measures and the related problem of interpreting null results. The second problem involves the effects of sampling from a disabled population if the disorder under investigation has multiple unknown origins.…
