Recurrent global dynamics underlie perceptual grouping

Arrays of ambiguous objects often appear to group into a single interpretation. Examples include Attneave's triangles and the dynamic dot arrays of Ramachandran and Anstis. However, there are other displays in which perceptual grouping fails. We find that in a variety of such displays—which int...

Description
Summary:Arrays of ambiguous objects often appear to group into a single interpretation. Examples include Attneave's triangles and the dynamic dot arrays of Ramachandran and Anstis. However, there are other displays in which perceptual grouping fails. We find that in a variety of such displays—which interpretations are seen, or whether grouping occurs at all—depends on whether the ambiguous property of the objects can be assigned values consistent with a single viewer position or motion. This implies that grouping depends on the visual system developing a 3-D scene model which constrains the relation of the viewer to objects in the scene.
