SART sustained attention task
About 5 minutes · Physical keyboard
Press Space once for every number except 3. When 3 appears, do not press anything. Give equal importance to speed and accuracy. You can respond after the number disappears, until the next number appears.
18 practice rounds, then 225 scored rounds. Practice is not scored.
A physical keyboard is required for this version. The questionnaire works on touchscreens; these two tasks are currently designed for computer keyboards.
