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 ...
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.
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.
This limit is referred to as the finite capacity of short-term memory. Short-term memory capacity is often called memory span, in reference to a common measurement procedure. In a memory span test, the experimenter presents a list of items (e.g. digits or words) of increasing length.
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 ...

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.
