We measured the velocity of the motion aftereffect (MAE) caused by adaptation to a drifting sinusoidal luminance grating or an equiluminous chromatic grating by making use of two methods (matching, or nulling). The effect of spatial frequency regarding adapting and test stimuli, and that of velocity regarding adapting stimulus were also investigated. This study showed that the MAE velocity was not affected by the difference of the methods for the chromatic grating, whereas it was partly affected by the difference of the methods at some spatial frequencies for the luminance grating. The effect of adapting velocity was observed at the low spatial frequency conditions for the luminance grating. but not observed for the chromatic grating. Moreover, a significant interaction between the adapting and test spatial frequencies for the luminance grating was appeared. The properties of a luminance and a color channels in visual system were discussed.
