Amodal completion is the most common form of visual completion occurring when portions of an object are hidden, due to their occlusion behind another object (Michotte, 1951). Just as a shape is completed amodally behind another occluding shape, so is a color behind another occluding color or behind a lighting: a bright light reflected by a three-dimensional object. Four possible phenomenal combinations related to the amodal completion of color are shown: amodal or modal coloration or discoloration. Purposes of four experiments were: (1) to demonstrate the amodal completion of color under different stimulus conditions and under chromatic and achromatic conditions and (2) to extract the general principles ruling the amodal completion of color: “which, among many, is the color that completes amodally?” and, consequently, “which is the region of an object that determines its color?” The results showed the effectiveness of the amodal completion of color and that chromatic and achromatic conditions reveal different results. Four general principles of the amodal completion of color, useful to understand the more general problem of phenomenal organization of color, are suggested.

The Cost

The visual completion is the result of the integration of fragmented contours. The contrast polarity (or contrast sign) may affect this interpolation by strengthening the completion in a direction where the contrast polarity is preserved. This chapter illustrates some manifestations of these phenomena: the alteration of the alignment of the visual units and the illusory tilt of more complex visual organization. The occurrence of basic distorting effects underlying classic illusions—such as the Frazer illusion—is discussed. It is noted that the role of the contrast polarity rule in representing a “preferential” rule does not preclude other possibilities, such as edges completion, although it renders the contour detectable to a lesser degree.

Differences and similarities between modal and amodal completions can only be understood by considering the goals of visual completion: unity, shape, and perceptual quality. Pessoa et al. cannot reject representational accounts of vision because of flaws with isomorphic representations of perceptual quality: representations and processes for perceptual quality (modal completion) and most likely dissociable from those for unity and shape (nonmodal completions).

Objective Study

The visual information that specifies three-dimensional objects is often incomplete because objects occlude parts of themselves and other objects. Yet people rarely have difficulty perceiving complete, three-dimensional forms. Somehow the visual system seems to ‘complete’ partially specified objects. The perceptual processes underlying this seemingly effortless and immediate completion are poorly understood. Sekuler and Palmer designed in 1992 the primed-matching paradigm for the objective study of completion effects and their microgenesis. Results from the paradigm suggest that global processes may play a role early in perceptual completion, and that local processes dominate only under limited conditions of figural regularity and orientation. These results are not consistent with purely local or purely global theories of completion. The findings have implications for object perception and representation.
