Tap the screen quickly when a green circle appears. Do nothing when a red circle appears.
How to Play
A green or red circle appears on screen
If it's green, tap the screen as fast as you can
If it's red, do nothing — resisting the urge is the key!
Core Rule: Go Signal
When a green circle appears, tap quickly. Failing to tap is a miss and counts as incorrect.
Core Rule: No-Go Signal
When a red circle appears, you must withhold your response. Tapping is a false alarm and counts as incorrect.
Rules
Green circle (Go) — Tap the screen.
Red circle (No-Go) — Do nothing.
Missing a green circle or tapping on a red circle counts as wrong.
Tip
Go trials appear frequently, building an automatic tap habit — stop on red
Prepare to tap, but verify the color before executing
Speed matters, but accuracy earns even higher scores
The Go/No-Go task is a classic neuropsychological test for response inhibition. It is closely linked to prefrontal inhibitory control and widely used in ADHD research and impulsivity assessment.
