Both poorer DSS performance and the presence of perseveration can offer useful clinical information on the context of a thorough evaluation of the aMCI/DAT spectrum.Īlzheimer disease WAIS-IV digit span sequencing working memory. Discontinuation of DSS due to cross-task perseveration was frequently seen in, although not unique to, the DAT group. Conclusions: The DS sequencing results differed between the three clinical groups, which is consistent with the hypothesis that working memory declines would be evident on this measure. Digit Span Sequencing was significantly different in each group (DAT < aMCI < SCC), with a high rate of the DAT group showing cross-task perseveration. Results: Those with DAT performed significantly worse for DS Forward, Backward, and Total Score versus those with aMCI and SCC, whose performances were similar. This resulted in a sample of 290 individuals with DAT, 255 with aMCI, and 161 with SCC. Method: Seven hundred and six individuals were drawn from 1256 consecutive referrals who underwent a standard neuropsychological evaluation and obtained a consensus diagnosis from a neuropsychologist and a neurologist of DAT, aMCI, or having SCC. This study examines performance on DS for individuals from a memory disorder clinic diagnosed with amnestic mild cognitive impairment (aMCI), probable dementia of the Alzheimer type (DAT), or those with subjective cognitive complaints (SCC). Findings suggest a general advantage of musicians over nonmusicians in verbal working memory tasks, with a possible role of sensory modality and task complexity.Objective: The Digit Span (DS) subtest from the Wechsler Adult Intelligence Scale-4 th Edition (WAIS-IV) was updated to better measure working memory which is potentially clinically relevant as prior unreplicated studies showed that sequencing tasks differentiated normal from neurologic groups. In addition, the auditory and audiovisual spans (but not visual) were correlated with one subscale of the PROMS test. The WMI consists of two primary subtests, Digit Span and Arithmetic, and the supplemental LetterNumber Sequencing. Musicians had larger spans than nonmusicians regardless of the sensory modality and the concurrent task. Finally, music abilities of all participants were assessed using the Profile of Music Perception Skills (PROMS) test. The Arithmetic subtest, formerly part of the FFD, is now a supplemental subtest a change that greatly diminishes the influence of mathematical skills (Flanagan & Kaufman, 2009 Kaufman et. The Logical Memory subtest is available in the Fourth Edition of the Wechsler Memory Scale (WMS-IV). The Digit Span Forward, Backward, and Sequencing subtests are included in the Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV). The task was performed with or without a concurrent task (i.e., articulatory suppression) in order to explore the role of rehearsal strategies and also manipulate task complexity. The WMI is comprised of the Digit Span (Forward and Backward) subtest and the newly added Letter-Number Sequencing subtest. The Wechsler Memory Scale-Revised (1987) is out-of-print and is no longer available.
Here, musicians and nonmusicians performed a digit span task that was presented aurally, visually, or audiovisually. In addition, it is unclear whether there are specific music abilities linked with improved performance in the digit span. Literature suggests that the musicians’ advantage unfolds along two axes: sensory modality (musicians perform better when the task is auditory) and task complexity (musicians tend to perform better in the forward and not - for example - backward digit span). This superiority extends to memory tasks such as the digit span. Musicians have superior performances compared to nonmusicians in many auditory perception tasks.
