Digit Memory Game

This test measures your ability to "hold on" to information in working memory, which you often need to complete complex tasks. A series of numbers will be presented to you. You will have to store those numbers in memory and pull them back up for later use.

This test measures your verbal working memory ability. You will see a series of digits presented in a box at the top of the screen and your task will be to remember those numbers in sequence.

After a brief period of time, the numbers will disappear and you will use the keypad at the center of the screen to key in your response. As soon as you have entered your response hit the "OK" button.

For example, if you saw the string of digits below, you would enter "28659" with the keypad and hit "OK".

28659

The digit strings will increase in length with each successful trial. You will continue the task until you make two mistakes in a row.
