After a prolonged viewing of stimuli moving in one direction subsequent static stimuli appear to move in the opposite direction (the motion aftereffect; MAE). It is known that MAEs with achromatic luminance stimuli are enhanced when static reference stimuli are displayed. In this study we examined the effect of static reference on MAEs with isoluminant chromatic stimuli. The results were consistent with other studies and robust MAEs were observed when the adaptors and tests were modulated along a different color axis. Furthermore, the static MAE was increased by the reference only when the adaptor and/or test were achromatic. In contrast, the reference did not have an effect on the MAE with a dynamic test. The results revealed that luminance and chromatic signals are processed independently in an early stage, and share common motion mechanisms later in higher stages.
