Mind-wandering (MW) is a universal cognitive process that is estimated to comprise [approximately] 30% of our everyday thoughts. Despite its prevalence, the functional utility of MW remains a scientific blind spot. The present study sought to investigate whether MW serves a functional role in cognition. Specifically, we investigated whether MW…

This investigation provides internal consistency reliabilities for the Wechsler Memory Scale--Fourth Edition (WMS-IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from 0.00 to 0.93 for Adults and 0.25 to 0.94 for Older Adults. Three of 91 Adult…

The hippocampus has long been recognized as important for the formation of long-term memory. Recent work has suggested that the hippocampus might also be important for certain kinds of spatial operations, as in constructing scenes, shifting perspective, or perceiving the geometry of scenes and their boundaries. We explored this proposal using a…

Autobiographical memory difficulties have been widely reported in adults with autism spectrum disorder (ASD). The aim of the current study was to explore the potential correlates of autobiographical memory performance (including depressed mood, rumination, working memory and theory of mind) in adults with ASD, relative to a group of typical adults…

JS is a highly able, well-educated 37 year old man with Asperger syndrome. A recent qualitative paper (Boucher, 2007) described his self-report of verbal and visual memory difficulties. The present paper used the WMS-III to compare the memory profile of JS to that of the adults with HFA in the Williams et al. (2005) WMS-III paper. Results show…

The rate at which people process information appears to influence many aspects of cognition across the lifespan. However, many commonly accepted measures of "processing speed" may require goal maintenance, manipulation of information in working memory, and decision-making, blurring the distinction between processing speed and executive…

Objectives: To investigate the presence of apathy symptoms in adolescents and adults with ADHD as a behavioral manifestation of underlying motivational deficits and to determine whether apathy symptoms were associated with a specific neuropsychological profile. Method: A total of 38 ADHD participants (28 of the combined subtype [ADHD/C] and 10 of…

Objectives: To demonstrate that high IQ adults diagnosed with ADHD suffer from executive function (EF) impairments that: a) can be identified with a combination of standardized measures and self-report data; and b) occur more commonly in this group than in the general population. Method: 157 ADHD adults with IQ greater than or equal to 120 were…

Investigated performance on Russell revision of Wechsler Memory Scale and Digit Span subtest of Wechsler Adult Intelligence Scale by right-handed males with lateralized anterior and posterior brain lesions. Prediction that laterality and caudality of lesions would affect memory task performance was fully supported for the logical memory task and…

Examined whether delayed recall factor could be found by substituting percent retained (saving) scores for existing Wechsler Memory Scale-Revised (WMS-R) delayed recall subtests scores. Principal component analyses of age-corrected WMS-R immediate and save scores in mixed clinical sample (n=168) failed to find hypothesized save factor. (Author/NB)

A comparison of the Rivermead Behavioural Memory Test (B. Wilson, 1987) and the Wechsler Memory Scale--Revised conducted with 20 neurotoxin-exposed and 20 unexposed adults finds that the two tests do not differ significantly in their relationships to estimates of everyday memory, and using both tests does not improve prediction of memory function.…

The nature and magnitude of practice effects on the Wechsler Memory Scale-Revised (D. Wechsler, 1987) were studied with 64 adult college students. The clinically meaningful increase observed across the four test sessions highlights the importance of controlling for practice effects on repeated administration of neuropsychological measures.

Discusses Russell's (1975) system for administering and scoring the Logical Memory and Visual Reproduction subtests of the Wechsler Memory Scale. Certain innovations such as obtaining a delayed recall appear to be useful, but comparisons with other studies indicate difficulty with the impairment ratings that were devised. (JAC)

The Wechsler Memory Scale[R] (WMS-III) is a widely used measure of memory functioning that is useful in the assessment of individuals with dementia, traumatic brain injury, and substance abuse problems, among others. This book is designed to help mental health professionals acquire the knowledge and skills to use the WMS-III. The chapters are: (1)…

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…
