Thanks for doing this test! It is 9 items long but quite difficult so don't be discouraged if you find yourself unable to complete some items.
Imagine each of the shapes being folded up into a cube. The sides visible to you are on the outside of the cube
Select which of the four images folds up into a cube that is different from the other three. There is no time limit.
This is for a university psych project. We are trying out this new form of spatial ability test. It is much harder than most tests, and the mean score from our testing so far has been 3.64/9. Your participation is helping us get more reliable data for these items and is very much appreciated.
