| Abstract(in English) | We measured motion aftereffect (MAE) in a concentric sinusoidal grating stimulus that is composed of high and low spatial frequencies. One of the two spatial frequency components moved in the direction of expansion, and the other moved in the direction of contraction. When the static test stimulus was presented in the display, MAE for high spatial frequency components was stronger than that for low spatial frequency components both in expansive and contractive motion. When the flicker test stimulus was presented in the display, this tendency was reversed. Moreover, we found the asymmetry in MAE duration between expansion and contraction for high spatial frequency when the static test stimulus was presented. These results suggest that the dominance of high spatial frequency in MAE reflects the properties of the higher motion processing mechanism responsible for low temporal frequencies. |
