Dynamic visual noise
Dynamic visual noise "resembles the "snowstorm" on an untuned television" (Read & Cumming, 2005). When viewed with an interocular delay, "the noise appears to swirl in depth, with points in front of the screeen moving towards the delayed eyes, and points behind it in the opposite direction" (Read & Cumming, 2005). The dynamic visual noise is unlike the pulfrich effect, in that the depth perception experience is not merely a "trival consequences of stimulus geometry" (Read & Cumming,2005).
Thus, we see that the classical explanation of the classical pulfrich effect cannot account for the results experience by the Stroboscopic Pulfrich effect and the dynamic visual noise. In fact, in Lee’s 1970 paper, he explicitly said that the “classical explanation doesn’t seem to work for the Stroboscopic Pulfrich effect” (Lee, 1970).As a result, this gave birth to the joint encoding of motion and depth explanation.
