About the Mental Rotation Test
Mental rotation is the ability to picture an object turning in your mind. It underlies many everyday tasks, from reading a map to parking a car, and it is one of the most studied measures of spatial intelligence.
In this test the two shapes are either identical (one is simply rotated) or mirror images that no rotation can align. Mirror images are the tricky case, because a quick glance often makes a reflection look like a rotation. A well-known finding is that the bigger the angle, the longer the decision takes — a sign you really are rotating the shape in your head.
