Test Results
About This Test
Reaction Time measures the delay between a visual signal and your click, reflecting both perception and motor response speed.
How It Works
- Wait for the screen to change color.
- Click as soon as you see the cue.
- Multiple trials produce an average reaction time.
Scoring
The primary metric is average time in milliseconds (ms). Lower values indicate faster responses; typical adult averages cluster around 250–300ms.
Tips
- Focus your gaze near the cue area and avoid anticipating.
- Use a comfortable mouse setup and stable surface.
- Run several trials for a more reliable average.
How to Play
Instructions
- Click anywhere to start the test.
- Wait for the screen to turn green.
- Click as quickly as possible once it turns green.
- Complete five attempts to get your average time.
- A typical adult average is around 250–300ms.
The Science Behind
🧠Cognitive Theory
Reaction time measures the speed of information processing in the nervous system, from visual stimulus detection to motor response execution. This reaction time process involves multiple neural pathways including sensory perception, cognitive processing, and motor control systems. Reaction time testing is fundamental for understanding human cognitive performance.
⚡Neural Mechanisms
When a visual stimulus appears, signals travel from the retina through the optic nerve to the visual cortex for processing. The prefrontal cortex makes the decision to respond, sending signals to the motor cortex, which coordinates muscle movement through the spinal cord.
Key Brain Areas:
📊Research Findings
Average human visual reaction time is 190-250ms, with simple reaction time faster than complex choice reaction time.
— Laming, D. (1968). Information theory of choice-reaction times
Regular reaction time practice can improve reaction time by 10-15% through enhanced neural efficiency.
— Thompson et al. (2014). Cognitive training effects on reaction time
Reaction time increases by approximately 0.5ms per year after age 30 due to neural processing changes.

⚠️Common Mistakes to Avoid
❌ Anticipating the stimulus
✅ Solution: Wait for the actual color change, don't guess timing
❌ Poor mouse/hand position
✅ Solution: Keep hand relaxed, finger ready but not tense
❌ Looking away from screen
✅ Solution: Maintain focus on the center of the test area
❌ Practicing when fatigued
✅ Solution: Train when alert and well-rested for best results

💡Pro Tips for Success
FAQ
Why did I get "Too early"?
If you click before the screen turns green, the attempt is invalid and you need to try again. This prevents cheating by guessing the timing.
How is average calculated?
Your average is computed across the five valid attempts in the current session. We use the arithmetic mean of all successful reaction times.
Does hardware affect results?
Yes. Display latency (5-30ms), input polling rate, and background apps can all influence recorded times. For best results, use a gaming mouse and close unnecessary programs.
What's considered a good reaction time?
Under 250ms is above average, under 200ms is excellent. Professional gamers often achieve 150-180ms. The world record is around 120ms, though this requires exceptional genetics and training.
Can reaction time be improved?
Yes! Regular reaction time practice can improve reaction time by 10-20%. Focus on proper technique, consistent reaction time practice, and maintaining alertness during reaction time tests.
Why do my times vary so much?
Reaction time naturally varies due to attention fluctuations, fatigue, caffeine levels, and random neural timing. Consistent practice reduces this variability.
