Reaction Time Test
Test how fast you react to visual stimuli. Click or tap as quickly as possible when the box turns green.
You’ll complete 5 rounds, and your average reaction time will be displayed at the end. Slower or faster reaction times can reflect your alertness, fatigue, or even cognitive load.
Tip: Try this at different times of day. Your brain processes reactions differently depending on the level of fatigue, focus, and your environment.
