Abstract
The position constancy during head movement of a luminous spot in a dark room depends in part on the convergence state of the eyes. This supports a modified form of the theory that an optical-motion/head-motion comparator contributes to constancy. By incorporating convergence information, the comparator can allow [or the effect of parallax on the optical-motion/body-motion ratio.
