Reaction Time Test — Visual, Audio, F1 Mode

For simple visual reaction, the global median adult time is about 240 ms. Under 200 ms is very fast. Under 170 ms is elite — NBA athletes, professional gamers. Over 300 ms for an adult usually means fatigue, distraction, or slower processing. Our age-adjusted result tells you where you stand within your age bracket.

Light hits your retina and travels through thalamus to visual cortex — roughly 120 ms of neural pathway. Sound reaches the auditory cortex in as little as 80–100 ms via the cochlea. Audio reactions are typically 15–30 ms faster than visual. This is why sprinters react to a gunshot, not a flash.

Modestly. Training shaves 10–30 ms off — that's near the biological floor. Larger gains come from eliminating what slows you down: fatigue, poor sleep, dehydration, excessive caffeine (jittery, not faster), or uncomfortable input devices. Consistent sub-200 ms requires natural talent plus optimal state.

Moderate doses (50–150 mg, one small coffee) shave 5–15 ms off average reaction times. High doses (300+ mg) increase false-positives — you click too early. Effect peaks at 45–60 minutes and fades over 4–6 hours. One small coffee 45 minutes before a reaction-critical activity is close to optimal.

Peak reaction speed is around age 24, declining very gradually afterward. A 50-year-old averages about 30 ms slower than at 25. Experience and pattern recognition compensate — older gamers often play slower but smarter, positioning and predicting. Our age-adjusted percentile accounts for this.

Yes — faster than about 85% of adults 18–29. For pro esports, the median is around 170–180 ms, with 200 ms being fine but not elite. For F1 specifically, 200 ms is top-tier (F1 drivers average 180–220 ms). Context matters: 200 ms is world-class for driving, solid-but-beatable for competitive FPS.

Attention flicker (anticipating makes you faster on that trial), random-delay variance (longer waits yield slower reactions because you relaxed), fatigue across trials, practice effect (faster in the first few trials, then plateau). High variance (over 40 ms standard deviation) usually means you're not fully focused.

Fairly close. Real F1 drivers see 5 red lights come on one by one, then all extinguish simultaneously — they react to the extinction, not a color change. Published F1 driver reaction times average 180–220 ms from lights-out to clutch release. Our F1 mode uses the same trigger but measures click, not clutch, so results run 20–40 ms slower than real F1 data. Still an excellent benchmark against your own past tests.

Hand dominance creates a small but measurable reaction advantage — usually 20–40 ms. Your dominant side has more refined motor pathways from lifelong use, plus faster peripheral nerve conduction. A gap over 50 ms might suggest unilateral fatigue, an old injury, or simply never having used your non-dominant hand for clicking.
