Digit-span tasks

In cognitive psychology, the digit-span task refers to tasks often used to measure the storage capacity of the working memory (Reisberg, 2018). Using this paradigm, researchers ask a study participant to listen to a series of numbers (e.g., 6, 9, 4) and then immediately repeat the numbers back to the researchers. For each successful attempt, one number is added to the sequence. The final sequence length a person remembers is the digit span.
