Studies of Mental Rotation Indicate That

Studies of mental rotation indicate that:

A) participants are able to imagine rotation of a two-dimensional display but are unable to imagine rotation in depth
B) the greater the degree of rotation required, the more time needed to complete the rotation
C) participants seem able to compare objects in mental imagery without bothering to imagine these objects rotated into alignment
D) imagined rotation in depth is appreciably faster than imagined rotation in two dimensions
