Instructions:

1. Click on the black dots as they appear in the white circles.
   
2. 1 point per hit, minus 1 point per miss.
3. Do the test twice. Once with your right hand and once with your left hand.
4. Find your difference score: subtract the score of your NON-dominant hand from the score of your dominant hand. For example, if you are RIGHT handed and scored a 32 with your right hand and scored a 25 with your left hand:
   Difference score = 32 - 25 = 7

   Another example: if you are LEFT handed and scored a 20 with your right hand and scored a 30 with your left hand:

   Difference score = 30 - 20 = 10
