The COLOR and SHAPE Game will change slightly for the next rounds.


In the past rounds you were told before each round whether to identify the color or the shape of the presented objects.

For the next rounds you will not be told before each round whether to identify the color or the shape of the presented objects. Instead you will briefly see either the words 'COLOR' or 'SHAPE' or the letters 'C' (for Color) or 'S' (for Shape) on the screen before each object is presented.


If you see 'COLOR' or 'C', identify whether the object is RED or GREEN.

If you see 'SHAPE' or 'S', identify whether the object is a ◯ CIRCLE or a △ TRIANGLE.


Please try to respond as quickly and as accurately as possible.
