Perceptual coupling of multiple point-light figures

摘要: When confronted with multiple bistable stimuli at the same time, visual system tends to generate a common interpretation for all stimuli. We exploit this perceptual-coupling phenomenon investigate perception of depth in point-light figures. Observers indicate global orientation simultaneously presented figures while similarity between is manipulated. In first experiment, higher occurrence coupled percepts found identical figures, but coupling breaks down when either movement pattern or both viewpoint and phase-relation are changed. A second experiment confirms these results, also demonstrates that different actions can be subject perceptual as long they share exhibit equivalent degrees ambiguity. The data consistent an explanation terms differential contributions stored, view-dependent object action representations intera...
