Concentration Test — 2 Minutes of Sustained Attention
Frequently Asked Questions
How does the concentration test work?
It follows the Sustained Attention to Response Task (SART) used in attention research: digits from 1 to 9 flash past, and you press for every digit except 3. Pressing is easy — the hard part is withholding your response when the 3 appears, which only happens if you're genuinely paying attention.
What is a good concentration score?
Accuracy of 90% or higher over the two minutes is a strong score; 96%+ is excellent. Most mistakes are presses on the forbidden digit — they show your responses have gone onto autopilot, which is exactly what the test is designed to catch.
How can I improve my concentration?
Treat each digit as a fresh decision rather than settling into a pressing rhythm. More broadly, regular sleep, exercise, breaks from screens, and single-tasking measurably improve sustained attention over time.
Getting the most from the concentration test
This test measures sustained attention — your ability to stay focused on a task without your mind wandering or your accuracy slipping. Sustained attention is easy to overestimate: most people can concentrate hard for a short burst, but holding steady focus over two full minutes is genuinely demanding. It is the foundation of deep work, careful reading and error-free tasks.
How to improve your focus
- Remove distractions before you start — notifications are the biggest culprit.
- Work in focused blocks with short breaks, such as the Pomodoro method.
- Train attention gradually; like a muscle, it strengthens with regular use.
- Protect sleep and take real breaks — a tired brain cannot sustain focus.
