Introduction: There is reason to believe that many individuals with substance use disorders (SUD), who are in contact with services, have an undiagnosed intellectual disability. The aim of the present study was to investigate the prevalence of intellectual and borderline intellectual disabilities (ID/BID) among inpatients with SUD and to further…

This study found that the verbal and nonverbal behaviors of examiners during testing may have affects on the intelligence performance of adult subjects. (EK)

In this study, the manipulation of motivation conditions through explicit examiner's expectancy of good performance was used to improve significantly the performance on intelligence tests. (Author/KM)

Analyzed the intercorrelations among the 11 subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in the nine age groups in the normative sample. Results suggested that the factor structure underlying the WAIS-R is complex and that a large proportion of WAIS-R performance can be explained by a general intellectual factor. (LLL)

Performed orthogonal and oblique factor analysis using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample (N=1,880). Analysis of the variance components for each subtest at every age level revealed a substantial proportion of subtests at a wide range of age levels evidenced high or intermediate levels of specific…

The general ("g") factor is the most general and relevant cognitive ability. This factor is considered to be one of the most important predictors of academic achievement and of many other socially relevant behavioral outcomes. In the last decades, many researchers have investigated the possible changes in the relevance of the…

Found subjects of varying levels of neuropsychological impairment, administered revised Wechsler Adult Intelligence Scale (WAIS-R), obtained significantly lower Full Scale, Verbal, and Performance Intelligence Quotients (IQs) than did subjects administered original, full version WAIS. Indicated significant main effects for level of impairment for…

Compared the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R) in a sample of college students (N=70). A highly significant test order interaction was found. The WAIS-R will result in significantly higher ability estimates when administered following the WAIS than the WAIS will when following the WAIS-R. (JAC)

Identified groups with high and low levels of mistrust of Whites. Half of the participants in each group were then administered the WAIS by a white examiner. The remaining were tested by a Black examiner. The Black examiner-high mistrust group scored significantly higher than the White examiner-high mistrust group. (Author)

Results from a representative sample of 123 adults in the United Kingdom tested with the Wechsler Adult Intelligence Scale-Revised and a test of word identification time are in line with previous findings that speed of information processing is significantly related to performance IQ but not to verbal IQ. (SLD)

Performance on the Digit Span (DSP) and Digit Symbol (DSY) subtests of the Wechsler Adult Intelligence Scale (WAIS) have been said to be vulnerable to the effects of anxiety, seating arrangements, and sex of subject. To determine the effects of these variables on anxiety and test performance on the WAIS-R DSP and DSY subtests, 40 male and 40…

Intelligence quotient (IQ) differences among groups according to sex, and demographic and other variables have been explored for a variety of intelligence tests. This investigation analyzed data from the standardization sample for the 1981 Wechsler Adult Intelligence Scale-Revised (WAIS-R) to determine the relationship of WAIS-R IQs to the…
