The images will flash very briefly, so pay careful attention! Take your time answering and be as accurate as you can.
To respond "first", press the 1 key. To respond "second", press the 2 key. Please test these keys out now -- press the 1 and 2 number keys a few times. If the computer recognizes your responses, the border will briefly turn gray. If it does not, you may not be eligible for this experiment. During the experiment, your responses will only be recognized once the instructions are displayed (after both sets of shapes have appeared and disappeared).
The whole experiment will only take a few minutes; please stay focused!
