Frequently Asked Questions
What is the average human reaction time?
The average human reaction time to a visual stimulus is 200-300 milliseconds. Factors like age, fatigue, and alertness affect your score. Competitive gamers and athletes often achieve 150-180ms through regular practice.
How does the reaction time test work?
Wait for the screen to change color (the signal), then tap or click as fast as you can. The test measures the time between the color change and your click using performance.now() for millisecond precision. Multiple trials are averaged for a reliable score.
Why is reaction time important?
Reaction time matters in driving, sports, gaming, and everyday safety. Faster reaction times help you avoid hazards, respond to game events, and perform better in time-critical situations. Regular testing helps track cognitive health over time.
How can I get a faster reaction time?
Practice regularly, get 7-9 hours of sleep, stay hydrated, and reduce distractions. Caffeine can temporarily improve reaction time. Start on Easy difficulty and progress to Hard as you improve. Physical exercise and hand-eye coordination games also help.
