Holdnack, James A.; Zhou, Xiaobin; Larrabee, Glenn J.; Millis, Scott R.; Salthouse, Timothy A. – Assessment, 2011
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…

Miller, Delyana I.; Davidson, Patrick S. R.; Schindler, Dwayne; Messier, Claude – Journal of Psychoeducational Assessment, 2013
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…

Bowden, Stephen C.; Petrauskas, Vilija M.; Bardenhagen, Fiona J.; Meade, Catherine E.; Simpson, Leonie C. – Assessment, 2013
The Digit Span subtest from the Wechsler Scales is used to measure Freedom from Distractibility or Working Memory. Some published research suggests that Digit Span forward should be interpreted differently from Digit Span backward. The present study explored the dimensionality of the Wechsler Memory Scale-III Digit Span (forward and backward)…

Shelton, Jill T.; Elliott, Emily M.; Hill, B. D.; Calamia, Matthew R.; Gouvier, Drew – Intelligence, 2009
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…

Russell, Elbert W. – Perceptual and Motor Skills, 1982
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…

Bowden, Stephen C.; Cook, Mark J.; Bardenhagen, Fiona J.; Shores, E. Arthur; Carstairs, Jane R. – Intelligence, 2004
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…
