The Wechsler Adult Intelligence Scale-III (WAIS-III) was administered to 152 patients at a VA Medical Center. Means for age, education, and Full Scale IQ were 51.49 years (SD = 13.00), 12.43 years (SD = 2.00), and 92.61 (SD = 14.06), respectively. Of the 152 patients, 69 had substance abuse disorders, 39 had medical/neurological conditions, 27 had both substance abuse and psychiatric disorders,...

In the most extensive investigation to date of language in global amnesia, we acquired data from experimental measures and examined longitudinal data from standardized tests, to determine whether language function was preserved in the amnesic patient H.M. The experimental measures indicated that H.M. performed normally on tests of lexical memory and grammatical function, relative to age- and ed...

Introduction The Face Name Associative Memory Exam (FNAME) is sensitive to associative memory changes early in the Alzheimer’s disease spectrum, but little known about how healthy aging affects FNAME performance. We aimed assess effects on an extended version of test, which captures further abilities beyond recall and recognition domains measured original version.Method adapted versions Spain M...

We obtained data on the writing of 110 deaf or hard-of-hearing students attending public schools who completed the spontaneous writing portion of the Test of Written Language. The average written quotient for the sample was in the below-average range but within 1 standard deviation of the test mean. Forty-nine percent of the sample received written quotients within or above the average range. M...

Many studies have evaluated the utility of the Word Memory Test (WMT) as a symptom validity test. However, there is a lack of reference data for the WMT conventional memory subtests. The present study examined the demographic characteristics that influence performance on these subtests, in order to develop demographically corrected reference data. For this purpose, we administered the Dutch ver...

OBJECTIVE We tested mediation of birth weight and ADHD symptoms by multiple biologically plausible neurocognitive functions and evaluated familiality of observed indirect effects. METHOD 647 youth from 284 multiplex families with ADHD completed the Arithmetic, Digit Span, Vocabulary, and Block Design subtests of the Wechsler Intelligence Scale for Children (WISC). Multiple mediation tested WI...

This article reports an investigation into the empirical status of a little understood cognitive factor-tactile-kinesthetic ability. To this end, a variety of haptic tasks, including three subtests of the Halstead-Reitan Neuropsychological Test Battery (HRB), were administered to 108 participants, along with established markers commonly employed in contemporary psychometric investigations. The ...

The Boston Diagnostic Aphasia Examination Battery (BDAE) is one of the most widely used aphasia tests worldwide. Information about general population performance, however, is limited. This paper analyzes the effects of gender, age, socioeconomic status (SES), academic achievement, and occupation on the BDAE Spanish version. The BDAE was administered to a randomized sample of 156 occupationally ...

To examine patterns of executive dysfunction associated with ADHD, 123 children (54 ADHD, 69 controls) of ages 8-16 years were administered selected subtests from the Delis-Kaplan Executive Function System (D-KEFS). Children with ADHD performed significantly worse than controls on measures of both basic (less executive demand) skills and those with more executive demand from the Color-Word Inte...

Genetic and environmental correlations among 11 Wechsler Intelligence Scale for Children-Revised (WISC-R) subtests were estimated from a sample of 143 twin pairs using the methodology of multivariate behavioral genetics. The genetic correlations among subtests varied in magnitude and exhibited a pattern similar to corresponding phenotypic correlations. Correlations due to within-pair environmen...
