The McCarthy Scales, which were designed to assess general intellectual abilities in the 2 1/2 to 8 1/2 age-range, are described and criticized on the basis of substantial experience in their use as a research instrument. It is concluded that they are particularly useful for the assessment of the preschooler. (Author)

Mentally retarded youngsters (N=80) aged 6 to 16, were tested on the WISC-R, primarily to assess the continuity of measurement between the old and new WISCs. There was evidence to support the continuity of the WISC-R with its predecessor for retarded populations. (Author)

Subtest questions of the Wechsler Preschool and Primary Scale of Intelligence are ordered from least to most difficult. Test records of 89 females and 62 males revealed though questions were misordered for the present sample, misordering was not great enough to seriously affect subtest scores or interpretation of intratest scatter.

The incremental validity of factor scores from the Wechlser Intelligence Scale for Children-III (WISC-III) in predicting scores on the Wechsler Individual Achievement Test (WIAT) was studied in 283 nonreferred children and 636 referred for evaluation. The Full Scale IQ of the WISC-III was the best predictor of WIAT achievement. (SLD)

Factor models of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) for one, two, three, and four factors were tested using confirmatory factor analysis with a sample of 177 child psychiatric inpatients. The four-factor model proposed in the WISC-III manual provided the best fit to the data. (SLD)

States that 43 adolescents diagnosed as dyslexic/reading disabled had markedly lower scores on the WISC-III than on the earlier WISC-R. Reports that only 2 subjects had scores above the 25th percentile. Discusses the impact of lower WISC-III IQs on guidelines for classification of students as learning disabled. (PA)

Investigated the secular rise in IQ scores over 60 years in 12-to-14-year-old Estonian students using data from the 1930s for 307 students and data from 1997-1998 for 381 students. Results indicate that the secular rise is not occurring on the "g" factor. (SLD)

The validity of a technique for estimating premorbid intellectual functioning based on Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest performance and demographic information used in best-performance fashion was investigated with the 1,880 individuals from the WAIS-R standardization sample. Results support use of the approach. (SLD)

Ninety-four college students were administered the General Ability Measure for Adults (GAMA) and Kaufman Adolescent and Adult Intelligence Test (KAIT). GAMA IQs were significantly and moderately correlated with KAIT Fluid, Crystallized and Composite IQs, supporting the convergent validity of this instrument. Although significant correlations…

Investigated specific problem caused by traditional method of teaching students to administer Wechsler Adult Intelligence Scale-Revised. Analysis of 180 protocols by 26 graduate students revealed average of 8.8 mistakes per protocol. When errors were corrected, 81 percent of Full Scale intelligence quotients were changed. Students' performance…

This study examined cognitive correlates of social perception in 32 learning-disabled elementary students. Three subtests of the Wechsler Intelligence Scale for Children-Revised and the Profile of Nonverbal Sensitivity were used as measures. Subtests for Picture Arrangement and Comprehension seemed to have an inherent relation to social perceptual…

Attempted to develop a quantitative model using the Wechsler Intelligence Scale for Children-Revised (WISC-R) that could be used to predict those students most likely to be successful in gifted education programs. Study used two phases using two groups of elementary school students (N=161). Used subtests to predict program performance of gifted…

Analyzed the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test (PPVT), and the Peabody Individual Achievement Test (PIAT) in a psychiatric sample of 329 children from 6 to 16 years old. Found 4 factors: Verbal Comprehension, Verbal Achievement, Perceptual Organization, and Number…
