A. S. Kaufman (1994) recommended that clinicians substitute Symbol Search, a new subtest, for the Coding subtest when calculating Performance and Full Scale IQs on the Wechsler Intelligence Scale for Children-III. Tables are provided for accurate derivation of IQs, percentile ranks, and confidence intervals when this substitution is made. (SLD)

As an alternative to equally weighted difference scores, examined an orthogonal reliable component analysis (RCA) solution and an oblique principal components analysis (PCA) solution for the standardization sample of the Kaufman Assessment Battery for Children (KABC; A. Kaufman and N. Kaufman, 1983). Discusses the practical implications of the…

Related inspection time (IT) to intelligence using a measure that has nonconfounded factors of mental ability to determine whether the association is based on fluid IQ or perceptual processes. Results for 37 undergraduates suggest that IT is related only to fluid intelligence, supporting the notion that IT reflects some fundamental underlying…

The study evaluated speed as a factor in Wechsler Intelligence Scale for Children-Revised performance with 66 high scoring and 36 average scoring children (ages 3-15 years). Results cast doubt on the utility of speed bonuses in tests of general intelligence with gifted children. (Author/DB)

Evaluated relation of performance on the Stanford-Binet Intelligence Scale: Fourth Edition to performance on the Wide Range Achievement Test-Revised and Woodcock-Johnson Psychoeducational Battery: Tests of Achievement for 31 normal, elementary-aged students using both the area score and Sattler's factor score approaches. (Author/ABL)

Compared Wechsler Intelligence Scale for Children-Revised (WISC-R) and Stanford-Binet Intelligence Scale-Fourth Edition (SB:FE) in identification and assessment of 48 intellectually gifted students. Findings suggest that scores of SB:FE and WISC-R, while both measuring 'g' factor, produce varying scores for gifted; many children currently in…

Discusses the changes in psychological testing and the rapidity of their development. Describes trends in the role of the test user, technical methodology of test construction, and interpretation of test scores. (Author)

Intelligence Quotient scores are only predictors of performance, not precise measures of intelligence. They are most useful in conjunction with other assessments of potential such as achievement tests and daily performance. An explanation of how scores are derived and a brief history of IQ testing are included. (IAH)

Comparison of scores on the Kaufman Assessment Battery for Children and the Wechsler Intelligence Scale for Children-Revised of 67 students (ages 6-12) referred for possible learning disabilities found strong relationships among all the global standard scores on both instruments with different score patterns for those with severe disabilities.…

Investigated the overlap between the Wechsler Intelligence Scale for Children - Revised (WISC-R) and the Halstead-Reitan Neuropsychological Battery (HRNB) in light of their use in diagnosing children's learning problems using scores for children (N=1,181) on the WISC-R and the HRNB. Results showed primary overlap between measures was attributed to…

Among findings of a comparison of 74 learning disabled college freshmen and non-handicapped peers on the Wechsler Adult Intelligence Scale--Revised, were no significant differences between verbal and performance scale discrepancies, more variable subtest performances by LD students, and lower mean scores by LD students. (Author/DB)

Of 100 DNA markers examined in an allelic association study, only 1 showed a replicated association with IQ in samples totaling 107 children. How the gene marked by the particular restriction fragment length polymorphism was tracked and its mitochondrial origin identified is described. (SLD)

For DNA markers in or near genes of neurological relevance, allelic frequencies were compared for groups of high- and low-IQ children (total sample of 86). This study adds 40 markers to the 60 already studied. Only one showed a significant association with IQ in original and replication samples. (SLD)

The impact of general control processing and working memory capacity on a measure of abstract intelligence was examined with 577 military recruits. A new multicomponent latent trait model for covert response was applied to item response data for matrix problems. General control processing has a stronger impact. (SLD)

Compared high-risk (n=20) versus low-risk (n=15) children in their performance on Wechsler Preschool Primary Intelligence Scale at pre- and postkindergarten levels. High-risk group had, at birth, experienced prematurity and/or illness. Both groups demonstrated increases in performance: high-risk children showed increases predominantly in…
