The "Raven's 2 Progressive Matrices Clinical Edition" (Raven's 2; Raven, Rust, Chan, & Zhou, 2018), published by NCS Pearson, is an individually administered nonverbal assessment of general cognitive ability developed to measure "educative abilities," defined as the ability to think clearly and solve complex problems in…

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…

Published by the Canadian Test Centre (CTC), "Insight" represents a group-administered test of cognitive functioning that has been built entirely upon the Cattell-Horn-Carroll (CHC) theoretical framework. "Insight" is intended to be administered by educators and screen entire classrooms for students who present learning…

The authors review the "Advanced Clinical Solutions for WAIS-IV and WMS-IV". The "Advanced Clinical Solutions (ACS) for the Wechsler Adult Intelligence Scale-Fourth Edition" (WAIS-IV; Wechsler, 2008) and the "Wechsler Memory Scale-Fourth Edition" (WMS-IV; Wechsler, 2009) was published by Pearson in 2009. It is a…

We propose three latent scales within the framework of nonparametric item response theory for polytomously scored items. Latent scales are models that imply an invariant item ordering, meaning that the order of the items is the same for each measurement value on the latent scale. This ordering property may be important in, for example,…

The Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II; Wechsler, 2011), published by Pearson, is a newly updated abbreviated measure of cognitive intelligence designed for individuals 6 to 90 years of age. Primarily used in clinical, psychoeducational, and research settings, the WASI-II was developed to quickly and accurately…

IQ test scores should be corrected for high stakes decisions that employ these assessments, including capital offense cases. If scores are not corrected, then diagnostic standards must change with each generation. Arguments against corrections, based on standards of practice, information present and absent in test manuals, and related issues,…

In this article, the authors review the Reynolds Intellectual Assessment Scales (RIAS; Reynolds & Kamphaus, 2003), an individually administered test of intelligence for use with individuals between the ages of 3 and 94. The RIAS represents the newest intelligence test on the marketplace and incorporates the most current intelligence test theory…

In this article, the author reviews the Reynolds Intellectual Assessment Scales (RIAS), an individually administered test of intelligence appropriate for ages 3 through 94 years with a conormed, supplemental measure of memory. The RIAS should be administered by examiners who have formal training in assessment. In this regard, the RIAS is a…

The Perkins-Binet Test of Intelligence for the Blind, Form U; the Wechsler Intelligence Scale for Children-Revised (WISC-R), Verbal Scale; and the Wide Range Achievement Test (WRAT) were administered to 52 low-vision children in the third, fifth, seventh, and ninth grades. Results indicated that the mean ten scores on the two tests of intelligence…

Within the field of psychological assessment, the Wechsler scales continue to be the most widely used intelligence batteries. The concepts, methods, and procedures inherent in the design of the Wechsler scales have been so influential that they have guided most of the test development and research in the field for more than a half century. This…

Measuring student intelligence has been problematic in the United States since standardized testing first began in the early 1900s. The omnipresence of standardized testing in student populations is illustrated by the most popular contemporary tests which are used by some scholars to advance the notion that intelligence differences between whites…

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

The results of this experiment clearly indicate that the presence of induced anxiety in a testing situation can depress the subject's level of performance on the WISC. (Author)

Data from the WAIS, WISC, and WPPSI Standardization samples were used to reappraise validity of all short forms of two, three, four, and five subtests. Results were compared with those given by McNemar's formula. The corrected formula gave lower values and selected "best short forms that differed from McNemar's formula. (Author)
