How to Play the Reaction Time Test

The Reaction Time Test measures how quickly you can respond to a visual stimulus. This reflex test is used by athletes, gamers, and researchers to assess cognitive response speed.

  1. Click or tap anywhere to begin the test
  2. Wait for the screen to turn from red to green
  3. Click or tap as fast as you can when you see green
  4. Your response time will be shown in milliseconds

What's a Good Reaction Time?

The average human reaction time is around 200-250 milliseconds. Professional gamers and athletes often score under 180ms. Scores below 150ms are exceptional. Your reaction time can be improved with practice and is affected by factors like sleep, caffeine, and age.

Fun Fact: The fastest recorded human reaction times in laboratory settings are around 100-120ms, approaching the biological limits of neural signal transmission.
