⚡ Quick answer
Sustained Attention is a free browser test in the continuous-performance style. Letters flash one at a time and you respond to every one except the target X. It measures vigilance: your ability to hold steady focus over time. The accuracy score is non-medical and self-relative, compared only to your own best.
Key takeaways
- Tap for every letter except the target X.
- Trains vigilance - holding steady focus over time.
- Free, in-browser, no sign-up; accuracy saved on your device.
- Not a diagnosis; compare only to your own past scores.
Staying alert for one second is easy; staying alert for a full minute while nothing exciting happens is the real test of attention.
Try it above: tap for every letter that flashes - except the target X, where you hold back.
How to play
The test runs for about 75 seconds and scores your accuracy as a percentage.
- Watch the letters flash one at a time in the panel.
- Tap the TAP button for every letter that appears.
- Do NOT tap when the letter is X - that is the target to skip.
- Both correct taps and correct skips count toward your accuracy.
No sign-up is required and your best accuracy is saved on your device.
What it trains
This is a vigilance task, closely related to continuous performance tests.
- Holding steady attention when nothing dramatic happens
- Catching the rare target without slipping
- Resisting the drift into autopilot tapping
Honestly, it mainly improves your focus on this specific task - pleasant practice, not a measure of your overall attention.
Why focus drifts over time
Repetitive, low-excitement tasks make the mind wander, so most people slip a little as the test goes on.
- Early letters feel easy to track
- Mid-test is where lapses creep in
- A steady rhythm helps more than rushing
The honest way to read your score
Your accuracy reflects one session and how rested you feel - compare it only with your own earlier attempts.
