Abstract
It has been hypothesized (Graham, 1963) that reversals in the Ames window are the outcome of a resolution of ambiguous differential angular velocity cues by linear perspective cues. This theory was tested. A parallel projection of the window on an opal glass screen was used as the stimulus. Ss almost always reported two apparent reversals per rotation. The long vertical side of the figure was always apparently in front of the short vertical side. These results were interpreted to be in line with theoretical expectations.
