The capacity to perceive depth is critical for an
observer to interact with his or her surroundings.
During observer movement, information about depth
can be extracted from the resulting patterns of
image motion on the retina (motion parallax). Without
extraretinal signals related to observer movement,
however, depth-sign (near versus far) from motion
parallax can be ambiguous. We previously demon-
