The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to 56 learning disabled children, using standard assessment procedures and format as outlined by Wechsler. Abbreviated Intelligence Quotient (IQ) scores were then derived by applying the Kennedy-Elder (K-E) formula. Frequent IQ classification changes rendered the K-E…

Results of the Test of Nonverbal Intelligence (TONI), Wechsler Intelligence Scale for Children-Revised (WISC-R), and Wide Range Achievement Test were compared for 66 learning disabled children in grades one through six. The TONI mean score was found to be significantly different from the WISC-R Performance Intelligence Quotient (IQ). Implications…

Examined the Wechsler Scales as predictors of academic achievement for a sample of Native Americans (N=75) from the Columbia Basin area. Results indicated significant Verbal-Performance discrepancies with mean Verbal scores significantly below the normative mean and Performance scores at or above the normative mean. (LLL)

The relation between average deviation, as determined using the Illinois Test of Psycholinguistic Abilities, and Stanford-Binet intelligence scores was examined using a preschool sample. Results revealed a curvilinear relation between total average deviation and Stanford-Binet intelligence scores. Use of average deviation as an index of…

Results of the study indicate that regardless of the presence or absence of verbal approval by the examiner during the administration, there was no significant difference in children's test performance on the WISC. (Author)

Investigated capability of WISC-R Verbal Comprehension (VC), Perceptual Organization (PO), and Freedom from Distractibility (FD) factor scores to predict academic achievement as measured by the Wide Range Achievement Test (WRAT). Multivariate multiple regression analysis revealed FD and VC factors predict WRAT reading, spelling, and arithmetic…

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

Examined the effects of different types of reinforcement on the performance of Black males diagnosed as being mildly mentally retarded. Children given tangible or culturally relevant rewards obtained significantly higher scores than did children given either no reinforcement or traditional social reinforcement. (Author)

Investigated the measurement properties and practical utility of Bannatyne's recategorized WISC-R scores. Analyses of the scores of Caucasian learning disabled children indicated that, as a group, these students were characterized by the predicted Spatial-Conceptual-Sequential pattern. This was not found to be true for Mexican-American learning…

Children (N=30) ages 6-10 were selected who had been referred for psychological evaluation from the public schools. WISC-R was significantly lower than WISC FS IQ's and similar to S-B L&M IQ's. The use of the WISC-R over the WISC will result in greater numbers of children being classified as retarded. (Author)

Indices of item difficulty and item discrimination were analyzed for the items comprising the Wechsler Intelligence Scale for Children-Revised as obtained from a group of 142 subjects with Full Scale IQs below 96. Evidence indicates increase in the number of items on the WISC-R helped increase its internal validity. (Author)

Both the WISC and the WISC-R were administered to 54 children, with one half taking the WISC first and the other 27 taking the WISC-R first. Differences between mean subtest scaled scores and mean IQs were found to be influenced by the sequence of the tests. (Author)

Investigates the factor structure of an intelligence scale for White, Mexican American, and African American children. Examined 4541 non-referred children and looked at verbal comprehension, perceptual organization, and freedom from distractibility. Results indicate differences in the intelligence scale's factor structure across groups, raising…

Discrepancies between IQ and Index scores on the WISC-III were investigated for a sample of students with Specific Learning Disability (SLD) and with mental retardation and evaluated but not classified. Consistent with the WISC-R literature, the discrepancies between Verbal and Performance IQs and higher Performance than Verbal IQs (which…

Kaufman Brief Intelligence Test (K-BIT) and Wechsler Intelligence Scale for Children-Revised (WISC-R) were administered in counterbalanced order to 35 referred students. Although K-BIT intelligence quotient (IQ) Composite correlated significantly with WISC-R Full Scale IQ scores, mean scores differed significantly. Results provide moderate support…
