TWO-DIMENSIONAL FIELD EFFECTS AND STATIC SLANT PERCEPTION

E riksson , E. S. Two-dimensional field effects and static slant perception. Scand. J. Psychol ., 1968, 9, 19–32.—The model for two-dimensional field effects as developed in a previous article makes possible certain predictions concerning perceived shape which, taken together with the subjective slant principle, result in predictions of the perceived slant of a circle or a surface composed of circles. Data were obtained which agreed with these predictions, showing that the geometrical shape slant invariance hypothesis is an inadequate model for depth perception. Some implications for gradient theory, Helmholtzian theories and Gestalt theory are discussed.
