Abstract(in English) Anstis (2001, 2004) suggested that the footsteps illusion is due to confusion between contrast and velocity signaling in the motion detectors of the human visual system. In order to test this hypothesis, two experiments were carried out. In Experiment 1, magnitudes of the footsteps illusion in dynamic and static conditions were compared. We found that the illusion was even more prominent in the static condition than in the dynamic condition. In Experiment 2, the magnitude of the illusion was measured with a temporally-modulated background, instead of a spatially-modulated background. The results showed that the magnitude of the illusion was much reduced in this condition. These results indicate that the footsteps illusion can be considered as a sequence of a static geometrical illusion induced by the striped background and that motion detectors play a minor roll at best.
