Objects in a scene are likely to occlude other objects partially and are itself likely to be partially occluded. A central question, therefore, is how the visual system resolves the resulting surface correspondence problem by successfully determining which surfaces belong to which objects. To this end, a recently developed dynamic grouping methodology has determined whether pairs of adjacent surfaces are grouped (Hock & Nichols, 2012).

Show moreObjects in a scene are likely to occlude other objects partially and are itself likely to be partially occluded. A central question, therefore, is how the visual system resolves the resulting surface correspondence problem by successfully determining which surfaces belong to which objects. To this end, a recently developed dynamic grouping methodology has determined whether pairs of adjacent surfaces are grouped (Hock & Nichols, 2012). The grouping of adjacent surfaces, which depends on their affinity state, is indicated by the direction of perceived motion across one surface when its luminance is perturbed. In the current stimuli, which consists of a horizontal surface partially occluded by a vertical bar, dynamic grouping also can occur for nonadjacent surfaces, providing they are linked in two-dimensions by a connecting surface. Results indicate that the dynamic grouping motion is stronger for amodal completion entailing the perceptual grouping of nonadjacent surfaces behind an occluder.
