Digit-span tasks can be given forwards or backwards, meaning that once the sequence is presented, the participant is asked to either recall the sequence in normal or reverse order. [8] Digit-span tasks are the most commonly used test for memory span, partially because performance on a digit-span task cannot be affected by factors such as ...
Although the format of the forward and backward Corsi block test are analogous to the forward and backward forms of the digit span task (which tests verbal memory span rather than visuo-spatial memory span), the backward Corsi block tapping test differs from the backwards digit span task in its relative difficulty.
Serial sevens (or, more generally, the descending subtraction task; DST), where a patient counts down from one hundred by sevens, is a clinical test used to test cognition; for example, to help assess mental status after possible head injury, in suspected cases of dementia or to show sleep inertia.
The WAIS-5 introduces several new subtests, particularly in the working memory domain, with Digit Span Sequencing and Running Digits now being the core subtests that compose the Working Memory Index. Digit Span Forward, Digit Span Backward, Spatial Addition, Symbol Span, and Letter-Number Sequencing may also be used to construct the Expanded ...
The backward digit span test is more complex than the forward digit span test, and it has a significantly higher g loading. Similarly, the g loadings of arithmetic computation, spelling, and word reading tests are lower than those of arithmetic problem solving, text composition, and reading comprehension tests, respectively.
The digit-span test is a perfect example of a measurement for classically defined short-term memory. Essentially, if one is not able to encode the 7 plus or minus two items within a few minutes by finding an existing association for the information to be transferred into long-term memory, then the information is lost and never encoded.

The test can be used to measure both short-term and long-term spatial memory, depending on the length of time between test and recall. The test was created by Canadian neuropsychologist Phillip Corsi, who modeled it after Hebb's digit span task by replacing the numerical test items with spatial ones. On average, most participants achieve a span ...
