How It Works
- Click Start to begin the test.
- Wait for the screen to turn green.
- Click as fast as you can when you see green.
- Your reaction time is measured in milliseconds (ms).
Tip: Share your best reaction time with friends. Great for TikTok or Instagram challenges.
Understanding Your Score
| Range | Rating |
|---|---|
| Under 200ms | Excellent |
| 200–250ms | Above Average |
| 250–300ms | Average |
| 300–350ms | Below Average |
| Over 350ms | Slow |
Reaction time measures the speed of your neural pathways from visual stimulus detection to motor response. It involves three stages: stimulus perception, cognitive processing, and motor execution. Research shows reaction time peaks in the early 20s and gradually slows with age.
Tips for Improvement
- Minimize distractions and focus entirely on the screen.
- Get adequate sleep — fatigue significantly slows reaction time.
- Stay physically active — regular exercise improves neural processing speed.
- Practice regularly — repeated testing builds faster motor responses.
