Abstract Objective: Multiple contributors to neurocognitive impairment in individuals with sickle cell disease (SCD) have been identified. Research indicates that a history of cerebrovascular accidents are associated greater cognitive decline among children disease, specifically visual-spatial tasks. Studies also indicated the presence age effects within this population. The purpose research is...

The Wechsler Intelligence Scale for Children—Revised (WISC-R) and Standard Raven Progressive Matrices (SPM) Test were evaluated in the context of an intervention/program evaluation study and in terms of a proportionate representation model of test bias. A total of 26,300 boys and girls from 8 different ethnic backgrounds were evaluated over a 9-year period. An intervention based on monitoring o...

Genetic and environmental correlations among 11 Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests were estimated from a sample of 143 twin pairs using the methodology of multivariate behavioral genetics. The genetic correlations among subtests varied in magnitude and exhibited a pattern similar to corresponding phenotypic correlations. Correlations due to within-pair environmen...

African–White differences on the sub-tests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) in Zimbabwe are like the Black–White differences in the US in being positively associated with the sub-tests’ g loadings (g being the general factor of intelligence). Published means and S.D.s for 204 12to 14-year-old Zimbabweans on 10 WISC-R sub-tests were compared against those for 1868...

Scatter analysis of IQ profiles has a long and controversial history. We conducted this study to determine whether the validity of scatter information is any greater for 2 new IQ batteries, the Kaufman Assessment Battery for Children (K-ABC) and the Fourth Edition Stanford-Binet (SB4), than for the Wechsler Intelligence Scale for Children-Revised (WISC-R). Within a sample of referred children, ...

In this study, some executive function measures (Wisconsin Card Sorting Test [WCST], verbal fluency, and Trial Making Test [TMT], Form A and Form B) were correlated with Wechsler Intelligence Scale for Children-Revised (WISC-R) scores. Fifty 13- to 16-year-old normal children were selected. It was found that verbal fluency tests correlated about 0.30 with Verbal Intelligence Quotient (IQ) and F...

Fourteen patients with classic phenylketonuria (PKU) were treated with a phenylalanine restricted diet from early infancy. All had satisfactory dietary control, with serum phenylalanine concentrations ranging between 2 to 5 mg/dL. Dietary restriction was discontinued in all these children between ages 5 and 6 years, and a free diet allowed. Developmental testing was performed using the Cattell ...
