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…

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…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

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…

Intelligence tests are usually part of the assessment battery for the diagnosis of adults with learning disabilities (LD) and attention deficit hyperactivity disorder (ADHD). Professionals must ensure that inferences drawn from such test scores are equivalent across populations with and without disabilities. Examination of measurement equivalence…

Matched 31 elderly normals and 25 patients with suspected Alzheimer's disease for age and education and administered the Revised Wechsler Memory Scale (WMS-R). Results showed that the patient group performed significantly less well than the control group on all WMS-R subtests. (Author/LLL)

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…

Wechsler Memory Scale Memory Quotient (WMS MQ) 12 points below Wechsler Adult Intelligence Scale Full-Scale IQ (WAIS FSIQ) may indicate memory impairment. Investigated the relation of FSIQ to MQ when the Wechsler Adult Intelligence Scale-Revised rather than the WAIS is used. Discrepancy between FSIQ and MQ occurred less often with WAIS-R than with…

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)

Norms are presented for persons ages 56 to 93 years for each story from the Logical Memory subtests of the revised edition of the Wechsler Memory Scale following the methods used for other Mayo's Older American Normative Studies. Means and standard deviations are presented for 3-year interval age groups from age 61 to 88. (SLD)

Describes research involving adolescent marijuana abusers. Using Wechsler Memory Scale-Revised and Wechsler Adult Intelligence Scale-Revised found characteristics consistent with pattern produced by cerebral dysfunction including reduced memory indices in relation to intellectual function and attentional ability. Intelligence was found to be in…

Calculated mean scores for older persons utilizing data from previous studies that measured Wechsler Memory Scale performance in healthy samples and compared with those of younger adults and a sample of neurologically impaired age (N=384). Statistical analysis indicated significant differences in the performance of different age groups. (JAC)

Administered Russell's (1975) variant of the Wechsler Memory Scale to elderly individuals (N=175) to determine if memory deteriorates with age even when chronic medical problems are not present. Results demonstrated that memory progressively declined after age 65 in a population without medical problems and with above-average education and income.…

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.…

Wechsler Memory Scale-Revised (WMS-R) scores were analyzed for 82 epilepsy surgery candidates and used in combination with receiver operating characteristic curves to classify patients with left (LTL) and right (RTL) temporal lobe seizure onset. Results indicate that WMS-R scores used alone or in combination provide relatively poor discrimination…
