Go / No-Go test: reaction time and impulse control
A Go/No-Go reaction test online: tap for green circles, hold back for red squares.
Try a practice roundPlay today’s fiveHow it works
Shapes flash up one at a time. Tap for every green circle and don’t tap for red squares. Tapping a red, or tapping when nothing is showing, costs 300 ms, and missing a green counts as a full second.
What it measures
Go/No-Go tasks measure response inhibition: the ability to stop an action you are primed to make. They are widely used in psychology and attention research.
Because most shapes are greens, your brain builds a habit of tapping. The skill is staying fast on the greens while keeping the brakes ready for the reds.
What’s a good score?
In Reactdle, 380 ms or faster rates Sharp, up to 480 ms is Steady, and slower is Sluggish.
Tips
- Wait for the shape. Tapping on nothing costs as much as tapping a red.
- Both the color and the shape differ, so you can go by either one.
