Derivation of a hypothesis about monocular size and depth perception from a simple general perceptual principle
Robert M Lambert
Received 12 August 1974
Abstract. A viewer is assumed to look with one eye at a fixation point f and a reference point x of a surface in a frontal parallel plane. He can move his eye along its line of regard for f some distance ΔS; and we suppose that he can assess the ratio ΔR-1/ΔS, where R is the retinal separation between the images of f and x and ΔR-1 is the change in the reciprocal of R that attends his movement of a distance ΔS. A model is proposed that approximates the optical conditions of his stimulation, and that allows him to calculate the physical distance E between f and x and the distance S between f and the center of his eye in terms of ΔR-1/ΔS. His calculations of E and S are treated as perceptions of the linear extent and the distance of the surface on which the points f and x are located.
