Frequently Asked Questions
What is a reaction time test?
A reaction time test measures how quickly you respond to a visual stimulus, usually reported in milliseconds from when the signal appears to when you click.
What is a good reaction time?
Average human visual reaction time is around 250 ms. Under 200 ms is fast, and under 150 ms is excellent.
Why did I click too early?
Clicking before the screen turns green means you anticipated the signal. Wait for green — patience gives you an accurate score.
Does monitor refresh rate affect reaction time?
Yes. A higher refresh-rate display can reduce visual delay, which may improve measured reaction times slightly compared to a 60 Hz screen.
Can I improve my reaction time with practice?
Somewhat. Reaction time has a genetic baseline, but focus, sleep, and repeated drills can help you stay consistent and avoid false starts.
