Go/No-Go Impulse Control Test
Tap green, hold back on red — 30 quick trials show how often your finger moves before your brain says stop.
How to Play

- When it turns RED (No-Go), hold still — do NOT tap.
- Missing a green (1 second to tap) or tapping a red both count as errors. 30 quick trials — stay sharp!

A quick game version of the Go/No-Go task, a setup psychologists use to study response inhibition. Over 30 trials the board turns green 24 times and red 6 times in random order: tap green within 1 second, and keep your hands off red. Tapping a red or missing a green counts as an error, and at the end you see your accuracy, your average reaction time on green and how many reds you tapped. It's a game for fun, not a diagnostic test.
Frequently Asked Questions
Q. How does the Go/No-Go test work?
A. Tap the board within 1 second whenever it turns green, and keep your hands off when it turns red. One round has 30 trials — 24 green and 6 red in random order, and the first two are always green.
Q. What counts as an error, and how is accuracy scored?
A. Tapping a red and failing to tap a green within 1 second both count as errors. Accuracy is the share of the 30 trials you got right, so tapping every single time still caps you at 80%. One error or fewer earns the top rating, 2–3 the second, 4–8 the third, and 9 or more lands on 'Too Impulsive!'.
Q. How are leaderboard points calculated?
A. Points = accuracy (%) × 5, plus a speed bonus of (600 − your average green reaction time in ms) ÷ 10 when that is above zero. Accuracy carries almost all the weight, so holding back on red matters more than raw speed.
Q. Can this test diagnose ADHD or impulsivity?
A. No. The Go/No-Go task is a research paradigm for studying response inhibition, but this short game isn't a validated clinical test and its result isn't a diagnosis. If attention or impulsivity concerns you, talk to a professional.
