Modal and amodal completion generate different shapes.
Mechanisms of contour completion are critical for computing visual surface structure in the face of occlusion. Theories of visual completion posit that mechanisms of contour interpolation operate independently of whether the completion is modal or amodal--thereby generating identical shapes in the two cases. This identity hypothesis was tested in two experiments using a configuration of two ove...
متن کاملSetting boundaries: brain dynamics of modal and amodal illusory shape completion in humans.
Normal visual perception requires differentiating foreground from background objects. Differences in physical attributes sometimes determine this relationship. Often such differences must instead be inferred, as when two objects or their parts have the same luminance. Modal completion refers to such perceptual "filling-in" of object borders that are accompanied by concurrent brightness enhancem...

متن کاملModal and Amodal Completion in the Artwork of Coles Phillips.
Several decades before Gaetano Kanizsa (1913–1993) became famous for his drawings of modally completing flat triangles and amodally completing flat pacmen, there was an American illustrator named Coles Phillips (1880–1927), who exploited modal and amodal completion to generate the impression of volumes. At his peak of creativity and productivity, just over one hundred years ago, he was among th...
متن کاملAmodal completion and localization
In a three-line vernier acuity task, a central line was localized between two aligned line segments. Accuracy did not improve when the segments formed a unified amodally completed percept. In a two-line vernier acuity task, a line was localized below a target line placed next to a physically segmented flank stimulus. Shifts in mean points of subjective equality suggested that amodally completed...
