Digit span testing is a measure of memory span which is the number of items, usually words or numbers, that a person can retain and recall. Where numbers are used it is also known as digit span, and the test is called digit repetition.
This limit is referred to as the finite capacity of short-term memory. The capacity of short-term memory is often called memory span, in reference to a common procedure of measuring it. In a memory span test, the experimenter presents lists of items (e.g. digits or words) of increasing length.
