The strong differences in manifestation, prevalence, and incidence in dyslexia across languages invite studies in specific writing systems. In particular, the question of the role played by emergent literacy in opaque and transparent writing systems remains a fraught one. This research project tested, through a 4-year prospective cohort study, an…

Because of the Flynn effect, IQ scores rise as a test norm ages but drop on the introduction of a newly revised test norm. The purpose of the current study was to determine the impact of the Flynn effect on learning disability (LD) diagnoses, the most prevalent special education diagnosis in the United States. Using a longitudinal sample of 875…

The author discusses conclusions presented in two artcles by H. Vance et al. titled "Determining WISC-R (Wechsler Intelligence Scale for Children-Revised) Profiles for Reading Disabled Children" and "Developing Remedial Hypotheses from Ability Profiles." The validity of five distinct WISC-R profiles for reading disabled…

The authors reply to M. Miller's concerns regarding their work on Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles for reading disabled children. Among the criticisms addressed are those dealing with subject sampling, Ss not fitting into the five WISC-R profiles, and factor analysis procedures used. (SBH)

The author responds to rebuttals by F. Wallbrown et al. regarding criticisms of their research on Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles of reading disabled children. (SBH)

One-hundred and sixty-four Black, White, and Latino children (7-15years old) with possible learning disabilities were administered the WISC (Wechsler Intelligence Scale for Children) and the WISC-R (Revised) to examine the similarity in the amount of subtest scatter equivalence of meaning, and degree of equivalent diagnosis between the two tests.

A study involving 98 children (6 to 13 years old) in ten learning disabilities (LD) classes investigated the hypothesized pattern of recategorized WISC-R (Wechsler Intelligence Scale for Children-Revised) subtest scores into spatial, conceptual, and sequential areas. (SBH)

The study involving 40 learning disabled children (6-8 years old) investigated the relationships between the various indexes of the McCarthy Scales of Children's Abilities (MSCA) and the scales of the Wechsler Intelligence Scale for Children-Revised (WISC-R), and the comparability between the MSCA General Cognitive Index and the WISC-R Full Scale…

Forty-six Black children (seven- through ten-years-old) referred for learning or behavior problems were administered both the Wechsler Intelligence Scale for Children- Revised (WISC-R) and the WISC. Ss had significantly lower WISC-R than WISC score, supporting previous studies which suggest that the WISC-R norms are "tougher" than the…

The extent to which IQ scores can be influenced by the administrative method used was investigated with 101 children (6 to 16 years old) with behavioral and emotional difficulties. Findings demonstrated a strong relationship between WISC-R test scores and administrative procedures. (SBH)
