Tempo · Time Estimation Test
You get a target — say, 4.0 seconds. Press GO, count it out in your head, and press STOP when you think the time is up. No clock to watch. Just you and your brain's metronome.
How to play Tempo
Each of the five rounds gives you a target between 2 and 6 seconds. Press GO to start the hidden timer, count silently, then press STOP. The closer you land to the target, the more of the 20 points per round you keep.
What it measures
Tempo is a classic time-production task. Interval timing in this range is handled by a distributed brain network, and your precision reflects sustained attention as much as any 'internal clock' — attention drift is the main reason estimates wander.
Honest note: Counting 'one-thousand-one…' is allowed — that's a strategy, not cheating. Even with counting, attention lapses show up in your score.
What's a good score?
70+ out of 100 means your estimates are mostly within a few tenths of a second — genuinely good. 90+ is metronome territory. The percentile we show is an estimate based on typical distributions, not a clinical norm.
FAQ
Why do I always stop too early?
Under time pressure most people's subjective clock runs fast, so they undershoot. Arousal, caffeine and even background music measurably shift interval timing.
Does counting in my head defeat the purpose?
No — chronometric counting is itself a timing skill and everyone's allowed to use it. The score still reflects how steady your rhythm and attention are.
