The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory…

New editions of the Wechsler Adult Intelligence and Memory scales are now available. Yet, given the significant changes in these new releases and the skepticism that has met them, independent evidence on their psychometric properties is much needed but currently lacking. We administered the WAIS-IV and the Older Adult version of the WMS-IV to 145…

Having a sense of purpose is recognized as an important resource for maintaining health and well-being over the life span. We examined associations of individual differences in sense of purpose with levels and rates of change in indices of aging well (health, cognition, and depressive symptoms) in a sample of 1,475 older adults (M[subscript age] =…

According to the most widely accepted Cattell-Horn-Carroll (CHC) model of intelligence measurement, each subtest score of the Wechsler Intelligence Scale for Adults (3rd ed.; WAIS-III) should reflect both 1st- and 2nd-order factors (i.e., 4 or 5 broad abilities and 1 general factor). To disentangle the contribution of each factor, we applied a…

Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of…

The working memory (WM) construct is conceptualized similarly across domains of psychology, yet the methods used to measure WM function vary widely. The present study examined the relationship between WM measures used in the laboratory and those used in applied settings. A large sample of undergraduates completed three laboratory-based WM measures…

The Wechsler Memory Scale was administered to 112 patients who had been referred to a clinical psychologist for investigation of cognitive functioning with regard to possible or actual organic pathology of the brain. The aim was to replicate the factor structure of this test found in a previous study. (Editor)

The Revised Wechsler Memory Scale, Wechsler Adult Intelligence Scale subtests, and Halstead-Reitan battery were factor analyzed. Five types of memory were isolated: immediate verbal, recent verbal, recent figural, figural learning, and verbal learning storage. Loadings of memory and nonmemory tests indicate a closer relationship between some of…

Confirmatory factor analysis of Australian adaptations of combined Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wechsler Memory Scale-Revised (WMS-R) scores was conducted in a sample of 277 participants undergoing investigation for neurological disorders. The best-fitting model was a six-factor model representing the latent abilities of…

Reveals a two-factor structure (general retentiveness and memory) in the Wechsler Memory Scale for total male and female samples and for both males and females aged 13 to 39 years and 40 to 59 years but not for males or females aged 60 to 88 years. (Author/RL)

A 3-factor solution of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) in 260 adults with suspected head injury suggested relatively good construct validity for the factors, based on correlations with neuropsychological tests. Findings are discussed in terms of the multidimensional nature of neuropsychological tests and WAIS-R factors.…

This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…
