Determine your short-term memory span

Short-term memory holds a small amount of information for a few seconds, such as a phone number between reading and dialling it. The digit span, the number of digits a person can repeat back in order, has been used to measure it for more than a century.

In this TestMyBrain test, digits appear one at a time and you enter them in the order shown; the sequences get longer as long as you keep recalling them. Put simply, it measures how many items you can hold in mind at once.

On the following pages, you can determine your short-term memory span by completing a short task. It has to be completed in one sitting.

The results will be provided immediately after you have completed the final trial. Please note that the results you receive can only be reliable to the extent that you work attentively and without help.

This test is part of the validation study for the Quantitative Socionics Inventory. In case of any question, please write an e-mail (contact@quantitativesocionics.org) to the research team.
