The whole point is to test your internal sense of duration — a visible timer would defeat it.

Does time perception relate to anything?

It's studied in cognitive psychology as interval timing, with links to attention and rhythm.

Why different durations?

Mixing 2–8s prevents you from calibrating to a single rhythm.

Time Perception

~3 min

Time Perception measures how accurately you can estimate elapsed time without a clock — a direct benchmark of interval timing.

For each of five trials, press and hold the button, then release when you think the target duration has passed. No timer is shown.

Your primary score is the average percentage error across trials (lower is better), estimated against population norms.

Attention and arousal affect time estimates. This is a research-grounded benchmark (Evidence B), not a clinical measure.
