Abstract

Human observers were required to report whether a briefly- presented static grating appeared ahead of or behind a moving grating, while they fixated on a small marker in between the two gratings. A forced choice paradigm using the method of constant stimuli was adopted to measure the angle of phase corresponding to a perceptual alignment between the two gratings. The angle does not depend on spatial frequency and varies linearly with the temporal frequency. When the experiment was carried out tracking the moving grating, no misalignment between two gratings was found.
