One of the most common obstacles to object perception is the fact that objects often occlude parts of themselves and parts of other objects. Perceptual completion has been studied extensively in humans, and researchers have shown that humans do complete partly occluded objects. In an effort to understand more about the mechanisms underlying completion, recent research has extended the study of perceptual completion to other mammalian species. Monkeys and mice also seem to complete two… 

Figures and Tables from this paper

Amodal Completion of Moving Objects by Pigeons
TLDR
Positive results suggest that motion may facilitate amodal completion by pigeons, perhaps by enhancing the figure – ground segregation process.
Perceptual Grouping in Pigeons
TLDR
Behavioral evidence is given that the perception of both occlusion and transparency is a common visual function shared by pigeons and humans, despite the structural differences between their visual systems.
Recognition of partly occluded objects by fish
The ability to visually complete partly occluded objects (so-called “amodal completion”) has been documented in mammals and birds. Here, we report the first evidence of such a perceptual ability in a
Does the Use of Natural Stimuli Facilitate Amodal Completion in Pigeons?
TLDR
It is suggested that a combination of various cues, including, eg, 3-D information and common motion in addition to surface and contour properties, may be required to induce a perceptual bias favouring visual completion of occluded portions.
Effects of Occlusion on Pigeons' Visual Object Recognition
TLDR
The recognition of occluding objects requires pigeons to learn to discriminate the object from the occluder; once this discrimination is mastered, occluded objects can be better recognized.
Prior experience affects amodal completion in pigeons
TLDR
It is suggested that experience with 2-D images may facilitate amodal completion in pigeons, perhaps via perceptual learning.
What perceptual rules do capuchin monkeys (Cebus apella) follow in completing partly occluded figures?
  • K. Fujita, A. Giersch
  • Psychology, Biology

  • 2005
TLDR
Experiment 5 showed that humans and capuchin monkeys basically follow similar perceptual rules in completing occluded contours, but the global regularity rule may be stronger in humans.
DOI:10.1068/p5402 Perceptual grouping in pigeons À
TLDR
It is shown that pigeons perceive occluded objects in the same manner as do other species and can recognize perceptually transparent surfaces when the effect is induced by the same perceptual mechanisms as occlusion, and given behavioral evidence that the perception of both occlusions and transparency is a common visual function shared by pigeons and humans.

The sensory information specifying objects is often optically incomplete : Objects occlude parts of themselves and other objects. However, people rarely experience difficulty in perceiving complete
Perception of partly occluded objects by young chicks
TLDR
The first demonstration of recognition of partly occluded objects in a bird species, the domestic chickGallus gallus, is provided, using the naturalistic setting made available by filial imprinting, a process whereby young birds form attachments to their mothers or some artificial substitute.
Completion of occluded objects in early vision : an exploration of spatial limits
TLDR
Results support the proposal of a preattentive completion process that is spatially limited, and the separability of completion from other cognitive processes was investigated using two strategies.
Local and Global Minima in Visual Completion: Effects of Symmetry and Orientation
TLDR
Results from the primed-matching 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.
Pigeons Are Sensitive to the Spatial Organization of Complex Visual Stimuli
TLDR
The results confirm Cerella's (1980) conclusion that pigeons discriminate the component parts of complex visual stimuli, but unless it is assumed that the scrambling deleted or created emergent features, the results disconfirm his conclusion that spatial organization plays no role in pigeons' picture perception.
Local and Global Processes in Visual Completion

Influences of closure, occlusion, and size on the perception of fragmented pictures
TLDR
The ability to recognize a repeated figure in stimuli where only fragments of the figures were presented support the idea of size invariance in object naming and difficulty in the smallest occluded condition is discussed.
