Average Reaction Time: Understanding Milliseconds

Reaction time is the delay between seeing a cue and making a response. Most online tests report it in milliseconds, but device latency, input method, attention and practice can shift the result.

How to use your results

Run several attempts on the same device and compare the median rather than a single best score. A slower result is not a diagnosis; this game is for entertainment.

How to read a millisecond result

One second equals 1,000 milliseconds. If a test shows 250 ms, the response took a quarter of a second after the cue was displayed. A smaller number means a faster response in this task, but a single attempt is noisy.

Make comparisons fair

Keep the same display, browser and input device. Complete several runs, rest between them, and compare the middle result. Anticipating the signal can produce an unrealistically low time; distracted trials can push the number up.

Try it yourself

Open the reaction time test and review your own results. The game is an entertainment benchmark, not a medical test or a universal population average.
