How to play Reaction Challenge
This XH0411 page combines Reaction Challenge with a guide to the decisions it asks you to make. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Use careful restarts to give your round a clear purpose.
Careful restarts
Start a fresh round when you want another attempt. Restarting may discard current progress; read the controls rather than assuming an account backup exists.
Your goal
Finish five valid responses. An early click does not count as a completed response; start that attempt again.
Step by step
- Start a round and wait without clicking.
- When GO appears, click or tap the large target.
- Read your response time and start the next round.
- After five rounds, the game shows the mean time.
Controls
Use the on-screen controls with a mouse or touch.
A useful example
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated.
Watch out for this
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test.
