時間知覚

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.
