This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

This study investigated Wechsler Adult Intelligence Scale-Revised (WAIS-R) profiles of deaf adolescents referred for academic difficulties. In addition, differences between referral deaf students and non-referral deaf peers were explored. The sample consisted of 28 severely-to-profoundly hearing impaired students enrolled in the School of…

A study was conducted to collect information on the origins of reading and learning disabilities and on the characteristics of learning disabled children. Data were collected from case histories and evaluation and follow-up reports for 372 learning disabled subjects, aged 6 to 22 years. Characteristics of the subjects were similar to those of…

A group of 41 learning disabled children were tested on the WISC-R. Two main questions were explored: (a) Do WISC-R tests assess "g" for learning disabled children to the same degree that they do for normal children? (b) Is there significantly more scatter among the tests for learning disabled than for normal youngsters? (Author)

The study investigated WISC-R subtest pattern scores of 58 learning disabled children. The evidence indicates that the low subtest scores on Arithmetic, Coding and Information were characteristic of this group. The study did not support the Verbal-Performance discrepancies as useful in the diagnosis of learning disabilities. (Author)

The relative accuracy of teacher judgments of academic performance in classifying students as learning disabled (LD) or nonhandicapped (NH) was contrasted to standardized tests of intelligence and academic achievement. Results indicated that teacher judgments were as accurate in separating LD and NH groups as standardized tests of intelligence and…

Twenty-one studies that reported mean score differences between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale are summarized. The differences are found to be minimal and are attributed to data bias and WJTCA's higher correlation with achievement. (EGS)

Assessed the prediction of learning proficiency on the basis of scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) with children (N=60) referred for learning disabilities. The WISC-R Coding accounted for over 50 percent of the variance in a controlled nonverbal paired associate learning measure and was the single best…

Individual differences in digit span, susceptibility to proactive interference, and various aptitude/achievement test scores were investigated in two experiments with college students. Results indicated that digit span was strongly correlated with aptitude/achievement scores, but did not indicate that susceptibility to proactive interference…

Factor-analyzed the WISC-R, PIAT, and WRAT scores of 183 male, learning disabled students. Findings suggest intelligence and achievement are composed of similar traits and skills. Therefore, comparison of individual achievement test scores with traditional Verbal, Performance, or Full Scale intelligence for learning disabled children may not be…

Results indicate that the Wechsler Intelligence Scale for Children (Revised) is a valid predictor of achievement for children referred for learning disabilities. The verbal Scale IQ, and the Freedom from Distractibility IQ proved especially useful predictors of academic achievement. (JAC)

The Wechsler Intelligence Scale for Children-Revised (WISC-R) Comprehension, Arithmetic, and Object Assembly and McCarthy Quantitative and Memory Indices were most sensitive to learning disabled students' achievement. Conversely, the WISC-R Similarities and Arithmetic and the McCarthy Verbal Index were most sensitive to achievement of nonlearning…

This study of elementary-level students compared behavioral patterns of 27 children showing a low nonverbal/high verbal (LNV) intelligence test profile and 38 children with a low verbal/high nonverbal (LV) profile. Results confirmed earlier findings that LNV children are perceived by teachers as significantly poorer than LV children in many…

This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

The authors present a diagnostic profile of Gerstmann's syndrome, the subject being a girl, aged 10 years 3 months, right-handed, and at the time of this study in her fourth school year (Grade 4). The subject's verbal and non-verbal IQ scores and additional assessment data were analyzed and summative responses given. The Senior South African…
