%X Flash lag effect describes a phenomenon that flash objects are perceived at a position behind physically aligned moving ones. Several contradictory explanations were proposed in recent years. The retina extrapolation proposal, based on a linear filter model, is the most competitive one to reach the neural mechanism of this effect. This proposal has been tested in the present study, in a second-order motion configuration, which was assumed to be irresolvable for the linear filter model. A luminance defined first-order motion and a motion-contrast defined first-order motion were used as control conditions. The results suggest that there was no significant difference between the amplitudes of the flash-lag effect in the second-order motion and in the first-order motion. This indicats that the retina extrapolation is not the main mechanism of the flash-lag effect. The results also suggest that the main mechanism of the flash-lag effect might locate above the combination of the first-order motion and the second-order motion computational channel.
