Keypresses
The pymetrics (Harver) Keypresses game is a finger-tapping task that measures motor speed alongside instruction-following. Your early, in-window, and post-STOP presses are logged separately.
How to Play
Wait for GO. From GO until STOP, press the spacebar as rapidly as possible using your dominant-hand index finger. Stop immediately when STOP appears.
Presses before GO and after STOP are recorded separately as start/stop compliance signals.
The live tap count stays hidden and is revealed only on the completion screen.
On a touch device, use the full-width TAP button in place of the spacebar.
In the real assessment
The real interval length is not publicly confirmed and may vary. This reconstruction uses the recommended 15-second default and, like the real task, does not show a live counter.
