How this test works

This test measures how fast you react to a signal you are waiting for. The circle stays grey for a random time, then turns green. Tap, click, or press Space or Enter as soon as you see green. After one practice round you play 10 timed rounds. Your score is the average time of your timed taps, in milliseconds. Taps that come too early are left out. Psychology labs have timed simple reactions like this since the 1860s.
