Press the panel to start. It waits at random for 1.5 to 4 seconds, then turns green. Tap or click only after the color changes. An early response is discarded and you restart that trial.
After five valid trials, Altamens shows the rounded arithmetic mean and the fastest single trial. The mean uses all five valid times; the fastest result is the minimum of those five values.
Screen, browser, device and input method all contribute to the recorded time. For personal comparisons, keep that setup consistent and look across several sessions. Altamens has not validated population norms for this browser test. It is an informal task, not a medical assessment, a driving-fitness check or a measure of general ability.

Common questions
The main result is the rounded arithmetic mean of five valid reaction times. The page also shows the fastest single trial. Early taps are excluded from both values.
Display latency, browser, operating system and input hardware affect a browser measurement. Compare your own sessions with the same device and input method where possible.
Altamens has not validated a population benchmark for this browser version. Treat the average and fastest trial as personal task results and compare several sessions made under similar conditions.
No. It is an informal visual-response task. It cannot diagnose a condition or assess attention, driving fitness or general performance.
