Vigilance
Sustained attention across a long, monotonous task
A pointer steps around a dial once a second for ten minutes. Roughly twice a minute it jumps two steps instead of one. Press space every time it does, and nothing else happens at all.
Free run: the first 20 seconds
You will sit the first 20 seconds of this test and get your score for them. Unlock it for $7.99, or every test for $25, to sit the full paper and see the breakdown behind the score. What unlocking adds
Before you start
- 20 seconds, continuous. There are no breaks and no pages.
- Press space (or click the dial) the moment the pointer jumps two positions instead of one.
- It will be boring. That is the test — the score that matters is how well you are still detecting jumps in the last two minutes.
- Leaving this tab voids the attempt.
