A New Perceptual Context-Superiority Effect: Line Segments Are More Visible against a Figure than against a Ground.

Wong, Eva; Weisstein, Naomi

Science, v218 n4572 p587-89 Nov 5 1982

Reports effects of context that are entirely perceptual. Visual discrimination was enhanced when line segments were flashed in a region that was perceived as a figure. Discrimination was substantially degraded when the same region was seen as ground although the physical stimulus remained identical throughout figure-ground reversals. (Author/JN)
