However, we are unaware of studies investigating the reliability of these tasks for WM assessment in older adults diagnosed with neurocognitive disorders. Both tests are commonly used in neuropsychological assessment of older adults with a diagnostic hypothesis of pathological aging (e.g., minor and major neurocognitive disorders). The Corsi Block-Tapping task uses nine cubes placed on a wooden board to assess visuospatial WM.
#Forward digit span vs backward digit span series
The Digit Span uses escalating series of numbers from 1 to 9, presented in a randomized fashion, to assess verbal WM. In both tests, the subject must repeat a series of stimuli in the presented order (forward) or in the inverse order (backward). The backward span of the Corsi Block-Tapping Task and its association with the WAIS-III Digit Span. Kessels RP, van den Berg E, Ruis C, Brands AM. The Digit Span and Corsi Block-Tapping tasks are frequently used in WM assessment. Furthermore, as a cognitive process, WM is key to understanding functional capacity in clinical samples. Despite the lack of a consensus definition and theoretical model to explain this function, its assessment is a key aspect in clinical practice, both for diagnostic and intervention purposes. Working memory: theories, models, and controversies. Working memory (WM) is a core aspect of executive function, related to temporary storage of information to be manipulated and used by other cognitive processes.
