摘要: Previous work has demonstrated that human beings employ a processing assumption, the boundary-flow constraint, in perceiving order of depth at an edge. Subjects perceive surfaces on basis relative motions image boundary and projected surface texture either side boundary. In present study, adult subjects viewed computer generated kinematograms which information provided only cue for order. The results Experiments 1 2 indicate common motion between differential can independently generate perception ordered depths surfaces. Experiment 3, we examined interaction two processes involved extraction from displays: (1) propagation foreground background to boundary; (2) computation while mechanism computes functions reliably when mean distance is 8.1o,surface may be disrupted distances this magnitude.
