1. You will perform this task 10 times with your right hand, and then 10 times with your left hand.
   (At any point in the process, the background tells you which hand you should be using.)
2. Move the mouse pointer to the target and click. The target should turn green .
3. Keep the mouse on the target; if it moves away, the target will change and you must click on it again to continue.
   (This does not affect your timing for the test.)
4. After a brief (random) pause, the target will disappear and reappear somewhere else. Move the mouse to the new location and click (a fast as possible).
5. Go back to step 3, 10 times for each hand.

When you have finished, your (anonymous) results will be submitted.
