Abstract
The perception of subjective contours has been ascribed to organizational factors which utilize implicit depth cues in the configuration. A recent alternative maintains that these apparent edges are due to the operation of simultaneous brightness contrast. Several demonstration figures are presented which show the relative inadequacy of contrast as an explanation for these phenomena.
