U.S. Supreme Court justices and other federal judges are, effectively, appointed for life, with no built-in check on their cognitive functioning as they approach old age. There is about a century of research on aging and intelligence that shows the vulnerability of processing speed, fluid reasoning, visual-spatial processing, and working memory to…

The purpose of this article was to describe an initial step developing a new scale to identify individuals with learning disabilities (LD) and test anxiety. Eighty-eight students answered the "Minnesota Multiphasic Personality Inventory-2" (MMPI-2). The participants were drawn from the following three groups: (a) adults with LD and test…

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…

Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…

Developed and tested a short form of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in 107 subjects. Results showed that when statistical corrections are made for item overlap between the two forms, the resulting correlation drops to .90 and that similar results were obtained in a cross-validation study.

The author provides an historical review of how he came to construct the Wechsler Adult Intelligence Scale (WAIS). Concepts underlying the WAIS are related to prior work in psychometrics. (RD)

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)

Factor analyzed the Wechsler Adult Intelligence Scale-Revised (WAIS-R) across nine age groups in the standardization sample. When three- and four-factor analyses were performed, the familiar three-factor structure (Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility) was clearly visible.

In the debate concerning psychological testing and reliability/validity issues, one issue which has had implications for the examinee is card or task rejection. Card rejection on the Wechsler Adult Intelligence Scale Picture Arrangement subtest attracted considerable attention. Picture Arrangement is not commonly a disturbing task. Assessment…

Tables permitting the conversion of short-form composite scores to full-scale IQ estimates have been published for previous editions of the Wechsler Adult Intelligence Scale (WAIS). Equivalent tables are now needed for selected subtests of the WAIS-III. This article used Tellegen and Briggs's formulae to convert the sum of scaled scores for four…

Techniques for constructing short forms of tests are discussed, and an example is given using the Wechsler Adult Intelligence Scale-Revised. Reliability and validity estimation equations are presented. (GDC)

A NEED FOR AN ADEQUATELY DEVELOPED AND STANDARDIZED INTELLIGENCE SCALE IN THE WHOLE OF LATIN AMERICA RESULTED IN THE WAIS PROJECT WHOSE AIM WAS TO TRANSLATE INTO SPANISH, ADAPT TO SPANISH CULTURE, AND STANDARDIZE THE WECHSLER ADULT INTELLIGENCE SCALE IN PUERTO RICO. FOLLOWING A DISCUSSION OF THE FOUR GENERAL GOALS, THE PROJECT REPORT OUTLINES THE…

The development and evaluation of an interactive computer-based administration and scoring program for the Slosson Intelligence Test (SIT) is discussed. A computer program successfully developed for administering and scoring the Wechsler Adult Intelligence Scale is cited to support the feasibility of developing this proposed SIT program. Testing,…

Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test.
