This study used simulation techniques to evaluate the technical adequacy of three methods for the identification of specific learning disabilities via patterns of strengths and weaknesses in cognitive processing. Latent and observed data were generated and the decision-making process of each method was applied to assess concordance in…

The Wechsler Intelligence Scale for Children (WISC) is the most commonly used intelligence test for children. Five years ago, a Spanish version of the WISC-IV was published (WISC-IV Spanish; Wechsler, 2005), but a limited amount of published information is available regarding its utility when assessing clinical samples. The current study included…

Analyzed intelligence and achievement test scores for 100 learning disabled boys to investigate the Wechsler Intelligence Scale for Children (Revised) as a predictor of Woodcock Johnson reading, mathematics, and written language scores. WISC-R performance IQ predicted the greatest variance. (JAC)

Results indicated that males obtained higher scores on the verbal subtests. Females scored significantly higher on coding than did their counterparts. The verbal v performance IQ dichotomy did not appear as useful evidence in the diagnosis of learning disabilities. (Author)

Investigated the concurrent validity of the Wechsler Intelligence Scale for Children (Revised) subtests and three IQs compared to Wide Range Achievement Test standard scores, in 28 learning-disabled children. Analysis showed no significant correlations between WISC-R and WRAT scores, indicating a lack of concurrent validity on the WAIS-R. (WAS)

Tests of the validity of the Wechsler Intelligence Scale for Children Third Edition Arithmetic, Coding, Information, and Digit Span (ACID) profile among 612 students with learning disabilities revealed that the ACID profile does not efficiently separate children with disabilities from those without disabilities. No ACID cutting score significantly…

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Black (N=95) and White (N=52) low socioeconomic children assigned to special education classes were initially given the Stanford-Binet and, three years later, the Wechsler Intelligence Scale for Children-Revised (WISC-R). Correlations between Stanford-Binet and WISC-R Full Scale IQs were significant in both ethnic groups, with r=.60 for the total…

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…

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…

The study sought to determine if significant predictive relationships could be found between diagnostic psychological test data and the changes in academic achievement of learning handicapped children participating in a resource specialist program for one period per day. The 102 students, with a mean age of 9 years, were administered the Wide…

A recategorization system developed by Bannatyne to categorize subtest scatter from the Wechsler Intelligence Scale for Children-Revised (WISC-R) is used as an alternative to isolated analysis of each individual subtest. Reading disabled, learning disabled, and educable mentally handicapped students are categorized according to their performance…

This article describes efforts to examine the validity of a screening process that provides objective data for multidisciplinary team meetings where consideration is being given to teacher referral of a student for assessment and possible placement in special education. In this study, the accuracy with which this process, called Problem Validation…

The long term predictive validity of the Wechsler Intelligence Scale for Children (WISC) and the Bender Visual Motor Gestalt Test for Children, when used for the educational placement of exceptional students, was investigated. In 1971, 225 learning disabled elementary school students were tested on the WISC and the Bender. The students were…
