What Is the Reaction Time Test?
This test measures how quickly you can respond to a visual stimulus. When the box turns green, click as fast as you can. The test runs 5 rounds and calculates your average reaction time.
How It Works
- Click the box to begin; it will turn red with a "Wait..." message
- After a random delay (1-5 seconds), the box turns green
- Click as fast as you can when it turns green
- If you click too early (before green), that round restarts
Average Reaction Times
- Excellent: under 200 ms
- Good: 200–250 ms
- Average: 250–300 ms
- Below average: over 300 ms
Frequently Asked Questions
What is a good reaction time?
Most people average between 250–300 ms. Athletes and gamers often score under 200 ms.
Why does the delay vary?
A random delay prevents you from anticipating the signal, giving a more accurate measurement.
Does clicking early count?
No, clicking before the box turns green is a false start and the round restarts.
