Explored the relationship between age and intelligence test performance across race and evaluated the developmental progression of scores and construct validity of the Kaufman Assessment Battery for Children in a sample totaling 2,615 children. No significant race or sex differences were found, supporting the validity of the K-ABC. (JAC)

The Kaufman Assessment Battery for Children (K-ABC) attempts to improve on the theory and technology of intelligence testing. The criteria used for this evaluation of the K-ABC are adequate theoretical basis; expanded range of abilities measured; incremental as well as convergent and discriminant validity; multiple meaningful scores; and training…

Six methods of measuring factorial similarity were compared with regard to outcome based on two large data sets, one for an intelligence test and the other for a personality test. All indexes yielded comparable results. Comparing factors determined at random, all indexes yielded comparable results leading to a conclusion of dissimilarity.…

Concludes that there are significant relationships between verbal IQ, full-scale IQ, and reading comprehension. (FL)

Examined whether scoring of Stanford-Binet test items might be influenced by the examiner's prior knowledge of subjects' ethnicity and IQ. Stanford-Binet protocols (N=36) of subjects from five to eight years old were divided into four groups and assigned four groups of examiners. Results suggested no bias. (Author/JAC)

The capability of the Slosson Intelligence Test and the Otis Lennon Mental Ability Test to predict academic achievement as measured by the Stanford Achievement Test is examined. The results indicated that the Slosson and Otis-Lennon significantly predict Stanford Vocabulary, Reading Comprehension, and Mathematical Concepts subtest scores.…

Explored the relationship between the Revised Peabody Picture Vocabulary test (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) for a sample of 38 mentally retarded children. Found the PPVT-R correlated significantly with the WISC-R Verbal Performance and Full Scale IQ scores. (Author)

A study of 22 learning disabled (LD) and normal children (mean age nine years) was undertaken to illustrate the research problems involved in using analysis of covariance to control for differences between LD and normal children on measures of intelligence. (SW)

Results show that Peabody Picture Vocabulary Test (PPVT) IQs are not interchangeable with Wechsler Intelligence Scale for Children-Revised (WISC-R) IQs in a sample of reading disabled children. The PPVT yielded higher IQs on the average than did the WISC-R, supporting results obtained with learning disabled students. (Author/BEF)

Compares the performance of learning disabled students on the WISC-R and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery. This study finds that learning disabled subjects performed more poorly on the Tests of Cognitive Abilities than on the WISC-R. (Author)

Regression lines for the prediction of achievement were compared across race through the Potthoff analysis, which provides a simultaneous test of slope and intercept values. Results of these comparisons generally supported the predictive validity of the Wechsler Intelligence Scale for Children-Revised across race with this referral sample of young…

Among the findings was that the factor structure of learning disabled children on the Wechsler Intelligence Scale for Children-Revised was somewhat more fractionated and complex than for normals, but not as complex as for reading disabled children. (Author/DLS)

Although the two scores were found to correlate significantly, the mean Index (45.8) was significantly lower than the mean IQ (64.) for this sample--suggesting that one should be cautious when using the McCarthy Index for placement. (Author/DLS)

A study of WISC-R and the Slosson Intelligence Test (SIT) reveal that SIT IQs were higher than WISC-R IQs in the upper range and lower in the lower range. Concludes that the SIT provides a good estimate of WISC-R full scale IQs when a regression equation is used. (Author)

The results of this study indicate that the WISC-R IQs are good predictors of achievement. They predict general achievement as represented by the PIAT total score and achievement in specific areas including reading recognition, mathematics, and spelling as measured by the PIAT. (Author)
