Frequently Asked Questions
How does the time accuracy test work?
Start the timer, then count in your head and press stop when you think the target time has elapsed. The timer is hidden so you can't cheat — it's a pure test of your internal sense of time. Your error is shown in milliseconds.
What is a good accuracy score?
Being within 500ms (half a second) of the target is good. Within 200ms is excellent. Most people are slightly late on short durations and slightly early on longer ones. Practice helps calibrate your internal clock.
Can I improve my time accuracy?
Yes. Regular practice with this test helps calibrate your internal clock. Try counting at a steady rhythm (one-mississippi), meditating to improve time awareness, and testing at different times of day to understand your patterns.
Why is this different from reaction time?
Reaction time measures how fast you respond to a stimulus. Time accuracy measures how well you track the passage of time internally. They use different brain systems — reaction time is about reflexes, while time accuracy is about temporal perception.
