Numerical Memory Experiment

The presentation of a series of digits orally by an examiner to an examinee is a common measurement typically referred to as Digit Span in such intelligence measures as the WISC-R and the WAIS-III. In the majority of these intelligence tests, the digits are presented to the examinee in an auditory format only, at which time the examinee is asked to repeats the digits back to the examiner. The rational of for this type of task is that is a good measure of short-term auditory memory and attention. Because auditory information must be recalled and repeated orally in the proper sequence, the digit span task is often described as a sequencing task (Sattler, 1992). The PsychExperiments Numerical Memory Experiment employs a similar format to Digit Span tasks found in such instruments as the WAIS-III, while comparing the individual’s short-term memory for digits presented in an auditory vs. visual format.
