Digit Span

Basic Characteristics

  • Description

In the Digit-Span task, subjects must remember a list of digits that are read by the examiner, and repeat the digits in either the same order they were presented (digit span forward) or in the reverse order (digit span backwards). The number of digits read to the subject is increased following successful trials, and the test terminates after two unsuccessful trials at the same sequence length. Backwards digit-span is often considered an indicator of working memory capacity.
