Amodal perception
Encyclopedia
Amodal perception is the term used to describe the perception
of the whole of a physical structure when only parts of it affect the sensory receptors. For example, a table will be perceived as a complete volumetric structure even if only part of it—the facing surface—projects to the retina; it is perceived as possessing internal volume and hidden rear surfaces despite the fact that only the near surfaces are exposed to view. Similarly, the world around us is perceived as a surrounding plenum, even though only part of it is in view at any time. Another much quoted example is that of the "dog behind a picket fence" in which a long narrow object (the dog) is partially occluded by fence-posts in front of it, but is nevertheless perceived as a single continuous object. Albert Bregman noted an auditory analogue of this phenomenon: when a melody is interrupted by bursts of white noise, it is nonetheless heard as a single melody continuing "behind" the bursts of noise.
Formulation of the theory is credited to the Belgian psychologist Albert Michotte
and Fabio Metelli, an Italian
psychologist, with their work developed in recent years by E.S. Reed and the Gestaltists
.
Modal completion is a similar phenomena in which a shape is perceived to be occluding other shapes even when the shape itself is not drawn. Examples include the triangle that appears to be occluding three disks in the Kanizsa triangle and the circles and squares that appear in different versions of the Koffka cross.

Perception is the process of attaining awareness or understanding of the environment by organizing and interpreting sensory information. All perception involves signals in the nervous system, which in turn result from physical stimulation of the sense organs...
