How this test works

This test measures how well you keep your focus on a dull task. For 3 minutes, watch a circle and tap as fast as you can each time it turns green. It turns green at random moments, 1 to 4 seconds apart. Your main score is the number of slow taps, 355 ms or slower: the moments when your attention slipped. You also see your average reaction time and your early taps. Sleep labs have used this 3-minute task since 2011, and its longer original since 1985.
