In this experiment you will see two sets of random dot arrays, one on the left side, one on the right side. One array will allways have more dots. Quickly decide if there are more dots on the left side or the right side.

  • Press A if more dots are on the left side
  • Press L if more dots are on the right side

If you perform this experiment on your mobile device, it is best performed in landscape orientation.
