Digit Span Task

Test your verbal working memory. Numbers will flash on screen — recall them in order (Forward) or in reverse (Backward).

Digit span is one of the oldest short-term memory measures. Forward span stresses simple maintenance; backward span adds manipulation load. Useful for tracking verbal working memory across days when you control sleep and stress.
