Test de Tiempo de Reacción.

A good reaction time for healthy adults is between 200 and 240 milliseconds. Competitive esports players and professional athletes frequently achieve 150 to 180 milliseconds, while the general human population averages approximately 250 milliseconds.

Auditory stimuli reach the brain significantly faster than visual stimuli. Auditory signals take approximately 8–10 milliseconds to reach the auditory cortex, whereas visual signals require 20–40 milliseconds to pass through the retina, optic nerve, and visual cortex. As a result, human auditory reaction time is typically 40–50ms faster (around 160ms vs 220ms).

Formula 1 uses a sequence of 5 red lights that illuminate one by one in 1-second intervals. Once all 5 lights are on, there is a randomized pause between 0.2 and 3.0 seconds determined by the race director before all lights extinguish simultaneously. Drivers must react to the lights extinguishing (lights out) rather than lights turning on.

Online reaction tests are accurate to within 10–25 milliseconds of dedicated lab chronometers. Precision depends heavily on your monitor's refresh rate (a 144Hz monitor refreshes every 6.9ms vs 16.6ms on 60Hz) and input device polling latency. Our test uses sub-millisecond performance.now() timestamps and zero-delay pointerdown event handlers to maximize measurement precision.

Simple reaction time involves responding immediately to a single predefined stimulus with one predetermined action (e.g., clicking when the screen turns green). Choice reaction time involves identifying different stimuli and selecting the corresponding correct response (e.g., our Color Stroop test), which adds cognitive processing time (typically 300–400ms).

Yes! Consistent practice (10–15 minutes daily), quality sleep (7–9 hours), physical fitness, and tactical caffeine consumption can improve reaction times by 10% to 20% over 4–6 weeks by optimizing neural transmission efficiency and motor preparedness.
