TestMyBrain Digit Span Backward
Determine your working memory span
Working memory is the ability to hold information in mind and work with it at the same time, as when you do mental arithmetic. It is closely related to reasoning ability and to how well people learn.
In this TestMyBrain test, digits appear one at a time and you enter them in reverse order; the sequences get longer as long as you keep recalling them. Put simply, it measures how much information you can not only hold in mind, but also rearrange.
On the following pages, you can determine your working 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.
