Abstract
24 students, 5 male and 19 female, were used in a repeated-measures factorial design to test two theories of Necker cube reversal. It was hypothesized that cubes with complete contours and high figure-ground contrast would reverse at faster rates than cubes with incomplete contours and low contrast if a sensory satiation theory (Köhler & Wallach, 1944) is valid, but at the same rate if the satiation of an orientation theory (Orbach, Ehrlich, & Heath, 1963) is correct. High contrast was achieved with black contours on white grounds and vice versa, low contrast with gray contours on black and white grounds. Cubes with complete contours, and stimuli in which only the eight corners of the cube were visible through 18-mm holes superimposed upon the complete cube, provided the contour variable. The results showed a higher reversal rate for cubes with complete contours but no contrast effect. The results were interpreted as supporting a sensory satiation theory.
