THE Wechsler Intelligence Scale for Children has grown logically out of the Wechsler-Bellevue Intelligence Scales used with adolescents and adults [4]. In fact, most of the items in the WISC are from Form II of the earlier scales, the main additions being new items at the easier end of each test to permit examination of children as young as five years of age. Even though the materials overlap, ...

The factor structure of the WAIS-R was examined in a U.K. sample free of neurological, psychiatric or sensory disorder (n = 120). Principal components analysis was performed with varimax rotation. Extraction of 2 and 3 factor solutions were specified a priori. For comparison purposes, the same procedures were followed with the U.S.A. standardisation sample data. Encouragingly for U.K. users of ...

Psychologists practicing in Canada must decide which set of normative data to use for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). The purpose of this study was to compare the interpretive effects of applying American versus Canadian normative systems in a sample of 432 Canadian postsecondary-level students who were administered the WAIS-IV as part of an evaluation for a lear...

Differences in sensory function between young (n = 42, 18-31 years old) and older (n = 137, 60-88 years old) adults were examined for auditory, visual, and tactile measures of threshold sensitivity and temporal acuity (gap-detection threshold). For all but one of the psychophysical measures (visual gap detection), multiple measures were obtained at different stimulus frequencies for each modali...

The risk of long-term damage to the CNS after exposure to mixed solvents in work environments is controversial. Thirty-six workers were studied who had been exposed to organic solvents for more than 10 years (mean 24.5 years) in a working environment. The workers and unexposed controls were studied with a battery of neuropsychological and cognitive tests. Significant group differences were obse...

In previous reports of studies of patients with alcoholic Korsakoff's psychosis, data were presented showing significant correlations between neuropsychometric measures of amnesia and the CSF levels of the major brain metabolite of norepinephrine (NE), which was consistently reduced among a large group of experimental subjects. Dopamine (DA) metabolite concentrations in the CSF of this same pat...

We investigated whether a relationship exists between frontal lobe volume and fluid intelligence as measured by both Cattell's Culture Fair test and the Wechsler Adult Intelligence Scale-Revised (WAIS-R) Performance scale, but not with crystallized intelligence as measured by the WAIS-R Verbal scale, in healthy adults, using two well-established image analysis techniques applied to high-resolut...

The present study surveyed assessment practices and test usage patterns among clinical neuropsychologists. Respondents were 747 North American, doctorate-level psychologists (40% usable response rate) affiliated with Division 40 of the American Psychological Association (APA), the National Academy of Neuropsychology (NAN), or the International Neuropsychological Society (INS). Respondents first...

The present study aimed to investigate the test-retest reliability of Wechsler Intelligence Scale for Children-Fourth edition (WISC-IV) in a sample 138 children with autism spectrum disorder...
