Three-dimensional object constancy: Coherence of a simulated rotating sphere in noise

摘要: Southeast Missouri State University, Cape Girardeau, 63 701 The maintenance of constant and coherent percepts three-dimensional objects, even in the midst visual noise, is important to our ability navigate environment. In present experiments, observers viewed computer-animated simulations spheres rotating around vertical axis depth. first experiment, addition noise form randomly moving display elements reduced subjects’ judgments depth accuracy their rotation-direction judgments, although phenomenal appearance structure was maintained throughout. second a change from frame orientation vectors that composed simulation reduced, but did not destroy, perceived accuracy. effect between successive frames depended upon length those vectors. It argued thatdynamic perspective— information provided by movement perspective together—is significant factor threedimensional object constancy.
