📖 How It Works

This test measures your simple visual reaction time — how quickly your brain perceives a visual signal and commands your hand to respond. Click Start Test, wait for the test area to turn green (the delay is random, between 1 and 4 seconds, so you cannot anticipate it), then click as fast as you can. After your chosen number of trials, your average reaction time is mapped to an estimated reaction age band.

Age Group	Average Reaction Time (ms)
18-25	under 260
26-35	260-299
36-45	300-339
46-55	340-379
56-65	380-429
66-75	430-479
76+	480+

A typical adult reacts to a visual stimulus in about 250 ms. Elite athletes and gamers often clock in under 200 ms, and reaction time gradually lengthens with age. The bands above are population averages — individual results vary with focus, sleep, caffeine, and practice.

💡 Why It Matters

🚗 Reflexes and Driving

At 60 mph a car travels about 88 feet per second. A 100 ms improvement in reaction time gives you nearly 9 extra feet of stopping distance — often the difference between a close call and a collision.

🎮 Gaming Performance

Fast-twitch games and esports reward reaction times under 250 ms. Training your reflexes, staying well rested, and eliminating distractions measurably improves your in-game response speed.

🧠 Aging and Cognition

Reaction time is one of the simplest markers of cognitive processing speed. It peaks in the early twenties and slows gradually with age as nerve conduction velocity declines — which is exactly why the bands shift upward.

🏋️ Training Improvement

Reaction time is trainable at any age. Regular practice, aerobic exercise, quality sleep, and good nutrition can shave tens of milliseconds off your response time and keep your reflexes sharp for longer.
