In spatial tasks, males found it easier to visualize geometrically and rotationally while females used references to objects when guiding through a route.
In obtaining the second and third images, the main objective is to filter out aliasing noise, so a rotationally symmetrical function may be more appropriate.
For example, imagine that a north-southoriented ice skater, in orbit over the equator of a black hole and rotationally at rest with respect to the stars, extends her arms.
