Time Perception
Press start, count in your head, and stop at what feels like 10 seconds. Three times.
You can also start with Space / Enter
Overview
The time perception test asks you to press start and then stop when you think 10 seconds have passed, without looking at a clock. You do this 3 times, and the average gap from 10 seconds, in milliseconds, becomes your score. A lower number means you stopped closer to 10 seconds. While you count, no elapsed time is shown and no sound plays, so you stop using only your own sense of time.
Rules
- Press start, count in your head, and stop when you think 10 seconds have passed
- No elapsed time is shown while you count
- After each try you see whether you were early or late, and by how much
- Your score is the average gap over 3 tries. A try you forget to stop ends at 30 seconds

FAQ
Can I count out loud?
Yes. Count however you like: in your head, quietly out loud, or by tapping a rhythm. Just do not look at a clock or another timer, because then it is no longer your sense of time.
Why the average of 3 tries?
With a single try, a lucky stop close to 10 seconds would become your score. Averaging 3 tries evens out luck and gives a value closer to how accurate your sense of time really is.
Is being early the same as being late?
Yes. The score depends only on the size of the gap from 10 seconds, not its direction. Each try shows whether you were early or late, so if you drift the same way every time, adjusting your counting pace a little can shrink the gap.
Why does my score change from day to day?
How time feels changes with sleepiness, nerves and focus. When you are in a hurry, time can feel longer and you may stop early. Watching your own results at a similar time of day is more useful than comparing with others.
