About Reaction Time

Visual Processing

Your brain takes 150–300ms to process a visual stimulus and send a motor command to your hand. Training can reduce this delay.

Age & Genetics

Reaction time peaks in your early 20s and gradually slows. Genetics influence your baseline, but practice makes a bigger difference.

Gaming Impact

Regular gamers typically react 10–20% faster than non-gamers. FPS and rhythm games show the strongest training effect.

Hardware Matters

Monitor refresh rate, input lag, and mouse polling rate all affect measured reaction time. A 144Hz monitor can shave 5–10ms off results.
