Your Reaction Time

Reaction time is how quickly you respond to a stimulus. It measures the delay between seeing a change and clicking.

Average reaction times:

Rating Time
Excellent < 200 ms
Good 200–250 ms
Average 250–350 ms
Below average 350–500 ms
Slow > 500 ms

Factors that affect reaction time:

  • Age: Fastest in your 20s, slows with age
  • Sleep: Fatigue significantly slows reactions
  • Caffeine: Can improve reaction time slightly
  • Practice: Regular testing improves performance
  • Distractions: Multitasking slows response

How it works: Click the button, wait for the box to turn green, then click it as fast as you can. Your time is measured in milliseconds.
