Figural/depth rating as a function of flicker synchrony for three conditions: (A) static edges (similar to Weisstein and Wong's conditions), (B) flickering edges, and (C) asynchronously flickering edges. Symbols above the figures represent edge flicker conditions, and symbols below them represent textural flicker conditions. Filled circles represent static, unflickering elements, open circles with flares represent flickering elements, and filled circles with flares represent elements that flicker in counterphase to the elements with open circles and flares. Positive ratings indicate results consistent with the ERG hypothesis. Error bars represent standard errors of the mean.
