Velocity matches were made by 4 to 9 Ss for two reference velocities, 30'/sec and 5°/sec. The perceived velocity decreased as either aperture size or stripe size increased. Brown's transposition principle did not hold completely when the aperture and stripe size increased propor-tionally. The results can be understood as simultaneous manifestations of the aperture and stripe effects. The effect of the luminance upon the perceived velocity was not clear, though the fusion threshold linearly increased as the log. luminance increased. The velocity was underestimated in horizontal motions as compared with vertical motions under high velocity.
