Symbol-Digit Substitution

A key is displayed at the top of the screen, matching nine symbols with the digits 1 9. Symbols appear in the box below, and the testee responds by tapping on the numeric button corresponding to the digit as quickly as possible. The number of correct and incorrect responses and the mean response time for correct responses is recorded.

This test runs on the 7" tablet application (PenScreenSix).
