Figure 8. Illusory motion and depth of a rotating band.

Illustrated are the instants just before and after FAS, with identical spatial distributions but opposite directions of motion. Top row: frontal views with two highlighted example dots (red and green). Middle and bottom rows: top views of the interpolated shapes, resulting from different combinations of illusory motion and illusory depth, again with two highlighted example dots (red and green). The arrows depict spontaneous reversals (green), reversals of illusory depth only (blue, constant illusory motion outcome of FAS), and reversals of illusory rotation only (red, illusory motion reversal outcome of FAS).
