“…The given local completion in figure 2b is based on linear good continuation and agrees, for example, with the model proposed by Wouterlood and Boselie (1992). [Note that the approach of Kellman and Shipley (1991) would not predict completion here because the edges do not meet the relatability criterion; see also Boselie and Wouterlood (1992). ]…”

“…This principle was referred to as the reliability criterion. Boselie and Wouterlood (1992) criticised this principle on several grounds and proposed their own local model (Wouterlood and Boselie 1992). In their good-continuation model, it is assumed that there is a tendency to describe a pattern by the smallest number of contour elements and changes of direction within and between these contour elements.…”

Global Visual Completion of Quasi-Regular Shapes

The topic of amodal completion has often been investigated by using partly occluded shapes that are regular. In research that has typically been done with displays such as these regular shapes, it has been shown that global aspects of a shape can determine completion. To see how robust these global influences in the completion process are, we investigated quasi-regular shapes, ie shapes with a certain overall regularity but not based on metrical identities. First, in experiment 1 participants had to complete quasi-regular shapes in a drawing task. Then, in experiment 2 the primed-matching paradigm was used. Results from both experiments provided evidence for global completions. In experiment 3 we found that multiple global completions can be primed, which, as a control experiment showed, cannot be explained by some inability of the visual system to see the difference between the different completions. These data support the notion that global influences on visual occlusion are apparent even when the partly occluded stimulus is outside the domain of regular shapes. Implications for a global approach are provided.

“…We agree with Kellman and Shipley (1991) that splitting is (mainly) due to local factors, although for a critique of the claim that completions do not occur for angles less than 908 one must see Boselie and Wouterlood (1992). However, we disagree with Figure 2.…”

Mirror Symmetry Opposes Splitting of Chromatically Homogeneous Surfaces

Chromatically homogeneous surfaces can be seen as single figures but also as two or more overlapping figures. Local factors such as relatability have been proposed in order to explain perception of two or more figures (Kellman and Shipley, 1991 Cognitive Psychology 23 141-221). However, even when these factors are at work, there are conditions favouring the perception of a single figure, which have not been explored so far. Here we propose that one such factor is the mirror symmetry of the surface. Three experiments were designed to test: (a) the main hypothesis, that mirror symmetry enhances perception of a single figure; (b) the role of orientation; (c) the effect of the number of axes of symmetry. The results show that (i) there is a good general correlation between mirror symmetry and perception of a single figure; (ii) vertical and horizontal axes of symmetry are the most effective; and (iii) the more axes of symmetry a surface has, the more likely is the perception of a single figure. These results suggest that mirror symmetry is an important factor in the perception of chromatically homogeneous displays. Some explanations are discussed, particularly one based on the rejection-of-coincidence principle [Rock, 1983 The Logic of Perception (Cambridge, MA: MIT Press)], and a version of the minimum principle in which the strength of the global solution depends on symmetry, whereas the strength of the splitting solution depends on the strength of local factors. In brief, global and local factors compete in determining the perceptual outcome in chromatically homogeneous surfaces.

“…According to this theory, completion tends to produce the impression of the most regular shapes (Buffart and Leeuwenberg, 1981). However, other researchers have shown that observers do not always perceive the most regular shapes (Boselie and Wouterlood, 1992). Other theories ascribe amodal completion to the use of volume cues to form the image (Tse, 1999) or common depth planes (Nakayama and Shimojo, 1992).…”

A new taxonomy for perceptual filling-in

Perceptual filling-in occurs when structures of the visual system interpolate information across regions of visual space where that information is physically absent. It is a ubiquitous and heterogeneous phenomenon, which takes place in different forms almost every time we view the world around us, such as when objects are occluded by other objects or when they fall behind the blind spot. Yet, to date, there is no clear framework for relating these various forms of perceptual filling-in. Similarly, whether these and other forms of filling-in share common mechanisms is not yet known. Here we present a new taxonomy to categorize the different forms of perceptual filling-in. We then examine experimental evidence for the processes involved in each type of perceptual filling-in. Finally, we use established theories of general surface perception to show how contextualizing filling-in using this framework broadens our understanding of the possible shared mechanisms underlying perceptual filling-in. In particular, we consider the importance of the presence of boundaries in determining the phenomenal experience of perceptual filling-in.
