It is controversial whether the magnitude of the motion aftereffect is greater when both inspection and test stimuli are the same color rather than different colors (color selectivity}. The present experiments show that the extent of color selectivity in the classical motion aftereffect depends upon {1} the duration of the interval between inspection and test, and {2} the nature of the stimulation during this interval. These findings are consistent with previous reports of two phases in the motion aftereffect and are interpreted in terms of the known properties of sustained and transient cells in the human visual system.
