Abstract Amodal completion is the representation of those parts of the perceived object that we don’t get sensory information from. In the case of vision, it is the representation of occluded parts of the objects we see. Amodal completion is not a perceptual curiosity, it happens virtually all the time we perceive.

Amodal Completion in Mouse Vision
Perception, 1993The question of whether phenomena of human perception such as amodal completion are also present in visual perception in the mouse was investigated. Three experiments based on a simultaneous-discrimination task were carried out with the aid of a jumping-stand similar to the one used by Lashley. The subjects were 36 male mice (DBA/J)

Amodal Completion is Not Completed Only behind the Occluder
Perception, 2009We investigated amodal completion with changes in two parameters: figure orientation, and the shape of the occluding and occluded figures. First, Markovich's [2002, Visual Mathematics4(1); http://www.mi.sanu.ac.rs/vismath/fila ] figure was presented in vertical, horizontal, and diagonal orientations.

Learning and Motivation, 2010
Abstract We trained two bonobos to discriminate among occluded, complete, and incomplete stimuli. The occluded stimulus comprised a pair of colored shapes, one of which appeared to occlude the other. The complete and incomplete stimuli involved the single shape that appeared to have been partially covered in the occluded stimulus; the complete ...

Amodal completion is modulated by lightness similarity
Attention, Perception, and Psychophysics, 2013The strength of amodal completion is known to be modulated by contour relationships and global shape. Some researchers have shown that amodal completion also depends on surface similarity, but they have not distinguished the relative importance of similarity in surface representations either pre or post lightness constancy.

Effective CAPTCHA with Amodal Completion and Aftereffects
Proceedings of the 10th International Conference on Ubiquitous Information Management and Communication, 2016Accounts on web services are always exposed to the menace of attacks. Especially, a large number of accounts can be used for unfair uses such as stealth marketing or SPAM attacks. Needless to say, acquisition of those accounts and attacks are automatically done by software programs called bots.

Abstract When the vertex of an occluded angle geometrically belongs to the side of the occluding surface, the occluded angle looks distorted. This characteristic effect of coincidental occlusion—called the Gerbino illusion—is consistent with the phenomenal rounding of angles observed under conditions of symmetrical occlusion.

Amodal completion of unconsciously presented objects
Psychonomic Bulletin & Review, 2014In the visual environment, objects often appear behind occluding surfaces, yet they are automatically and effortlessly perceived as complete. Here, we examined whether visually occluded objects that are presented below the threshold of awareness are amodally completed.

Smooth pursuit of amodally completed images
Experimental Eye Research, 2019In order to evaluate the effect of the parafoveal area of the retina on smooth pursuit, we compared the horizontal smooth pursuit of visible and amodally completed stimuli in people with central vision loss and controls. In the amodally completed stimuli, a black mask covered the bottom vertex of a moving diamond which is the feature whose movement ...
