Go / No-Go Reaction Game
Respond as fast as you can to green circles and hold back on red squares. Free practice for the reaction and inhibition tasks used in game-based tests.
How to play
- Tap the target area (or press Space) as soon as a green circle appears.
- Do nothing when a red square appears.
- Most shapes are green, which builds a habit of responding. The skill is stopping in time.
What it measures
Go / No-Go tasks balance speed against control: reacting quickly to what matters while not reacting to what does not. Very fast responses with many false alarms read differently from slower, more careful ones.
Research basis: this game is our own implementation of the Go / No-Go task. Verbruggen & Logan (2008), Journal of Experimental Psychology: General, 137(4), 649–672. ↗
Tips to improve
- Keep your eyes on the centre of the target area, not on your finger.
- Aim for steady speed. A fraction of a second slower usually removes most false alarms.
- After an error, reset and focus on the next shape. Do not slow right down.
Frequently asked questions
What counts as a good score?
High hit rate with few false alarms. On this practice version, catching over 90% of green circles while responding to fewer than 20% of red squares is a strong result.
Why are there so many green shapes?
Frequent targets make responding automatic, which is what makes stopping on the rare red shape a real test of control.
Does it work on a phone?
Yes. The target area responds to touch the moment your finger lands, so tap timings stay accurate.
