Go/No-Go test
Tap at green, keep your fingers still at red: the Go/No-Go test shows how well you react fast and still hold back. ← All concentration exercises
How it works
Pick a level
Easy: green and red circle, 1.2 s · Medium: plus blue squares, 0.9 s · Hard: digits, tap at every one except the 3, 0.7 s.
React
Tap the big field or press space. Pressing at a No-Go sign or missing a Go counts as an error.
Evaluate
At the end you see the mean reaction time, false presses and missed signs – and your best time per level.
Frequently asked questions
What does the Go/No-Go test measure?+
It combines reacting fast with holding a reaction back – psychology calls it impulse control or inhibition. The hard level resembles the SART, where you press at every digit except one.
What are good values?+
Few false presses matter more than speed. Many people get faster with practice – and make more false presses. Compare yourself with yourself on the same level and device.
Is there a worksheet?+
No – this exercise depends on fractions of a second, which only works on screen. For paper, try letter cancellation or the Schulte table.
Is this a medical test?+
No. The exercise is for practice and fun and gives no norm values.
