The central executive component of working memory has been argued to play an important role in the performance of span tasks, particularly backward span. Age-related decline in central executive function has also been reported, and yet there have been inconsistent findings to indicate that with increasing age, the discrepancy between forward and backward span increases. A secondary analysis of ...

OBJECTIVE The aim of this study was to determine the effect of light long-term ecstasy consumption on verbal short-term and working memory and to identify the cognitive processes contributing to task performance. METHOD Electroencephalogram was recorded while ecstasy users (N = 11), polydrug users (N = 13), and non-users (N = 13) completed forward and backward serial recognition tasks designe...

Background: Recent evidence suggests that the cerebellum is involved in cognitive functions. Theta burst stimulation (TBS), a modality of transcranial magnetic (TMS), on can change its contribution to working memory. Therefore, we hypothesize excitatory intermittent TBS (iTBS) would improve performance memory tasks, whereas inhibitory continuous (cTBS) disrupt it. Methods: As this an ongoing st...

In several studies, suppressed Digit Span performance has been proposed as a potential marker for deliberately poor performance in a neuropsychological evaluation. The purpose of this study was to document Digit Span performance patterns in the Wechsler Adult Intelligence Scale-Third Edition (WAIS-III; ) standardization sample and selected clinical groups. Base rate tables were generated for th...

In addition to episodic memory impairment, working memory may also be compromised in mild cognitive impairment (MCI) or Alzheimer's dementia (AD), but standard verbal and visuospatial span tasks do not always detect impairments. Objective To examine whether more complex verbal and visuospatial working memory tasks result in more reliable impairment detection. Methods The Digit Span (forward...
