Failures of lightness constancy, edge integration, and local edge enhancement.
In a CRT simulation of the "edge-substitution" paradigm [Gilchrist (1988) Perception & Psychophysics, 43, 415-424], observers adjusted the apparent reflectance (lightness) of a test surface to match incremental or decremental standards. Matches suggested that two factors contributed to the observed failures of lightness constancy: (1) the interpretation of the scene in terms of illumination and reflectance edges and their corresponding integration, and (2) edge-enhancement (the "crispening" effect) due to the local surround.[1]References
