The Digit-Span task is used to measure storage capacity of numbers in working memory.
Abstract
This experiment is a version of the Digit-Span memory task. The goal of the task is to assess a participant's ability to accurately recall a string of digits in the reverse order of how they were presented. The participant is shown a series of digits. The minimum length of digits presented is 2 (e.g., 68) and the maximum length is 8 (e.g., 85496371). For example, if a participant sees "389", then they need to recall the number "983."
Depending on whether the participant answers correctly, the task may become more difficult. If the participant gets 2 answers correct on a block, then digit length is increased. If the participant only gets 1 answer correct, then the block of trials is repeated again with different numbers even though the digit length remains the same. If a participant does not get any correct answers for a certain digit length, then the experiment concludes.
