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. The participant is shown a series of digits. The minimum length of digits presented is 3 (e.g., 638) and the maximum length is 9 (e.g., 628295702). The participant has to recall the digits exactly as they were presented.

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.
