In summary, this study shows that it is difficult to rotate images in the mind and see what they look like rotated. The had figures that looked like a duck one way, and, rotated 90 degrees looked like a rabbit. Same with a snail/seahorse. 1/3 of the Ss could rotate the image and see what it was, but only after they were asked previously to rotate something else. So it could be that they can't do it unless they know ahead of time that they might have to rotate-- which means they might have been rotating during the initial perception, which is easier.
