The present study examined the incremental validity of Wechsler Adult Intelligence Scale-4th Edition (WAIS-IV; Wechsler, 2008a) factor index scores in predicting academic achievement on the Wechsler Individual Achievement Test-2nd Edition (WIAT-II; Psychological Corporation, 2002a) and on the Wechsler Individual Achievement Test-3rd Edition (WIAT-III; Wechsler, 2009a) beyond that predicted by t...

An Investigation of the Relationship Between the Bender-Gestalt, Draw-a-Man, and Wechsler Preschool and Primary Scale of Intelligence by G. Edward Allen, Jr., Master of Science Utah State University, 1969 Major Professor: Glendon Casto Department: Psychology v This study investigated the relationship between the Bender-Gestalt, Draw-a-Man, and the Wexler Preschool and Primary Scale of Intellige...

In 15 normotensive subjects, 17 newly diagnosed, untreated hypertensive patients, and 22 effectively treated hypertensive patients, a battery of neuropsychological tests was given. All subjects were neurologically asymptomatic. The neuropsychological battery included tests evaluating global cognitive functions (Card Sorting Test, Wechsler Memory Scale, Progressive Matrices 1938), as well as spe...

The primary purpose of the study was to contribute to the validation of a recently developed test of functional abilities, the Bay area Functional Performance Evaluation (BaFPE). On the premise that aspects of intelligence influence functional performance, three subscales of the Wechsler Adult Intelligence Scale (WAIS) were administered, in conjunction with the BaFPE task-oriented assessment (T...

OBJECTIVES To develop supplementary methods for the analysis of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) in neuropsychological assessment. DESIGN AND METHODS Psychometric. RESULTS The following methods are made available: (a) provision of traditional confidence intervals (CIs) on index scores, (b) expression of the endpoints of CIs as percentile ranks; (c) quantificati...

The use of cognitive subtest profiles to hypothesize about children's learning strengths and weaknesses implicitly assumes that subtest profiles are predictive of academic performance. To test this assumption, Wechsler Intelligence Scale for Children-Third Edition (WISC-III) subtest profiles were decomposed into elevation, scatter, and shape components and sequentially regressed onto reading an...

Neurocognitive impairment is a detrimental complication of HIV infection. Here, we characterized the intellectual performance of patients with newly diagnosed HIV infection in southwestern Nigeria. We conducted a prospective study at Owo Federal Medical Center by using the adapted Wechsler Adult Intelligence Scale (WAIS). The raw scores were converted to standardized scores (z-scores) and corre...

A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or general level are Wechsler scales (46.9%), Britis...

Twenty-four studies utilizing the Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest--either the Reliable Digit Span (RDS) or Age-Corrected Scaled Score (DS-ACSS) variant--for malingering detection were meta-analytically reviewed to evaluate their effectiveness in detecting malingered neurocognitive dysfunction. RDS and DS-ACSS effectively discriminated between honest responders and di...
