❓ FAQ
What is a normal reaction time?
Visual reaction time (seeing a signal and clicking) normally ranges from 150–300ms. The average person is around 200–250ms, athletes around 150–200ms, and older adults 300ms or more. Factors include fatigue, caffeine, and practice.
Why does my result vary each time?
Reaction time is affected by attention level, anticipation, fatigue, and screen refresh rate. Multiple trials averaged together give a more reliable measure than any single result.
How can I improve my reaction speed?
Regular aerobic exercise (especially ball sports), adequate sleep, and staying focused all help. Cognitive training tools like the Stroop Task and Go/No-Go also improve inhibitory control and reaction speed.
