Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

Investigated the utility of considering Digits Forward (DF) and Digits Backward (DB) as separate components of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) through correlations with other intelligence tests. The findings of significant correlations indicate that although DF and DB tasks are related, the combination of these tasks into a…

The AGS Early Screening Profiles (AGS:ESP) instrument (P. Harrison, 1990) has been introduced recently as a screening instrument for predicting mental ability. A study was conducted to determine the degree of concurrent validity between the AGS:ESP and the Stanford Binet Fourth Edition (SB:FE), an instrument often used by psychologists to detect…

The correlations between the scores on the 1966, 1973, and 1979 norms on Raven's Standard Progressive Matrices for 140 economically disadvantaged students in grades three and five were significantly high. It seems appropriate to use any of the three sets of norms with economically disadvantaged students. (Author)

The Kaufman Brief Intelligence Test (K-BIT) was used as a screening instrument to predict Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores of 94 students referred for psychoeducational evaluations. Although the correlation coefficient between the K-BIT IQ Composite and the WISC-III Full Scale IQ was 0.771 for the entire…

When administered to 87 boys and 53 girls in screening procedures, significant score correlations between Quick Test and Wechsler Intelligence Scale for Children-Revised intelligence quotients and between the Wide Range Achievement Test Reading scores indicated that Quick Test is an effective tool for making valid brief estimates of intelligence.…

The concurrent validity of 2 brief intelligence tests, the Matrix Analogies Test-Short Form (MAT) and the Kaufman Brief Intelligence Test (K-BIT) with the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) using a sample of 50 urban students. The MAT and K-BIT appeared equally useful as screening tests. (SLD)

The predictive power of the Split-Half version of the Wechsler Intelligence Scale for Children--Revised (WISC-R) Object Assembly (OA) subtest was compared to that of the full administration of the OA subtest. A cohort of 218 male and 49 female adolescent offenders detained in a Texas juvenile detention facility between 1990 and 1992 was used. The…

The predictive power of the short-form Wechsler Adult Intelligence Scale of P. Satz and S. Mogel to provide equivalent information about IQ scores and age-corrected scale scores was not differentially affected by the side of the lesion for 63 patients with brain tumors. (SLD)

A 3-factor solution of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) in 260 adults with suspected head injury suggested relatively good construct validity for the factors, based on correlations with neuropsychological tests. Findings are discussed in terms of the multidimensional nature of neuropsychological tests and WAIS-R factors.…

Use of the Bender Visual Motor Gestalt Test in Australia was studied by comparing it with existing research, scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R), and other attainment tests. Subjects were 142 children aged 7-11 years. The suitability of the instrument in Australia is discussed. (SLD)

Rank-difference correlations between Memory-for-Designs test, Wechsler Intelligence Scale for Children (WISC), and Wide Range Achievement Test scores for two classes of educable mentally retarded children showed high negative correlations between Memory-for-Designs and WISC Full Scale IQs. Visual memory accounted for 84 percent of variance in…
