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…

Whenever a major intelligence or achievement test is revised, there is always renewed interest in the underlying structure of the test as well as a renewed interest in the scoring, administration, and interpretation changes. In this interview, Amy Gabel discusses the most recent revision of the "Wechsler Intelligence Scale for Children-Fifth…

Validation research for educational achievement tests is often limited to an examination of intended test score interpretations. This article calls for an expansion of validation research in three dimensions. First, validation must attend to actual test use and its consequences, not just score meaning. Second, validation must attend to unintended…

Educational assessment and, more broadly, educational research in the United States have entered into an era characterized by a dramatic increase in the prevalence and importance of test score use in accountability systems. This volume covers a selection of contemporary issues about testing science and practice that impact the nation's public…

Paper discusses advantages and disadvantages of using the Leiter International Performance Scale with autistic children and presents the results of a study comparing the performance of 18 autistic children on the Wechsler Intelligence Scale for Children-Revised and the Leiter. Results showed a high positive correlation between the WISC-R…

Introduces Stanford-Binet Intelligence Scale-Fourth Edition (SB4) as an attempt to revitalize Stanford-Binet by maintaining links with previous editions while simultaneously incorporating more recent developments found in other popular tests of intelligence. Discusses the SB4's theoretical foundation, materials and administration, scaling,…

Assesses proposed new demographic information formulas for estimating premorbid Wechsler Adult Intelligence Scales-Revised Intelligence Quotient scores. Investigated cross-validation of this index on a neurologically normal but clinically relevant criterion group and determined the neuropsychological utility of the formulas to discriminate between…

Reviews the administrative features, uses, development, standardization, reliability, and validity of the Multidimensional Aptitude Battery (MAB), a new group intelligence test designed to be a paper-and-pencil parallel to the Wechsler Adult Intelligence Scale-Revised (WAIS-R). (BL)

For mildly and moderately mentally retarded individuals, the Wechsler Adult Intelligence Scale-Revised measures at about the same level as the Wechsler Adult Intelligence Scale, and, consequently, it also produces much higher IQs than the Wechsler children's scales or the Stanford-Binet Intelligence Scale, Form L-M, despite high intertest…

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…

Eight subtests were selected from the Wechsler Intelligence Scale for Children--Third Edition (WISC-III) to make a short form for clinical use. Results with the 2,200 children from the WISC-III standardization sample indicated the adequate reliability and validity of the short form for clinical use. (SLD)

Tested criterion-related validity of Wechsler Intelligence Scale for Children-Revised (WISC-R) performance scale with Stanford Achievement Test, Special Edition for Hearing-Impaired Students (SAT-HI). Results indicated WISC-R performance scale has adequate criterion-related validity and SAT-HI percentile ranks may provide a better metric than…

Validity and reliability were calculated from data in the standardization sample of the Wechsler Adult Intelligence Scale--Revised for 565 proposed short forms. Time saved in comparison with use of the long form was estimated. The most efficient combinations were generally those composed of subtests that were quick to administer. (SLD)

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…

Two kinds of WISC-R short forms, item reduction and subtest reduction, are reviewed in terms of their ability to meet these criteria of adequacy: a significant correlation between the full scale IQ and the short form IQ, a non-significant difference between the full and short form mean IQ, a low percentage of IQ classification changes resulting…
