• The Rotating Snakes illusion is a motion illusion in which a static figure appears to rotate. Murakami et al. (2006) proposed the model that the biphasic shape of the temporal impulse response (TIR) function induces this illusion. We attempted to test this hypothesis by manipulating retinal illuminance because it is well known that the shape of the TIR function changes from biphasic to monophasic with decreasing retinal illuminance. The results indicated that the illusion strength indeed decreased with decreasing retinal illuminance. To obtain a better view of the change in temporal response property, the TIR functions were estimated by the double-pulse method (Burr & Morrone, 1993) under certain light conditions. We confirmed that the biphasic character of TIR gradually changed to monophasic with decreasing retinal illuminance. We argue that the biphasic characteristic of the TIR function contributes to the illusion strength.
