Essay / Research Paper Abstract

9 pages in length. The manner by which human beings perceive what they see is comprised of a multidimensional approach of part-based and surface-based visualization that serves to segment the object and then reconstruct it in the mind's eye so as to finally see it as a whole. A chair, for example, is looked at two ways: 1) as a holistic entity and 2) as an assemblage of four legs, a seat and a back support; walking around that chair confirms there is yet another side that cannot be viewed from the front but serves to complete the structural identification of this chair. A 2-D photograph of a chair, by virtue of this understanding, would thereby make holistic perception more of a challenge due to self-occlusion; only because we know chairs have a backside do we automatically presume the one in the photo does, as well. Bibliography lists 11 sources.

reconstruct it in the minds eye so as to finally see it as a whole. A chair, for example, is looked at two ways: 1) as a holistic entity and 2) as an assemblage of four legs, a seat and a back support; walking around that chair confirms there is yet another side that cannot be viewed from the front but serves to complete the structural identification of this chair. A 2-D photograph of a chair, by virtue of this understanding, would thereby make holistic perception more of a challenge due to self-occlusion (Singh et al, 2001); only because we know chairs have a backside do we automatically presume the one in the photo does, as well (Pirrone, 2001). "Entire objects, however, are not the only perceptual units. Indeed, the objects we see are not unstructured wholes they themselves have further part structure. We perceive a table, for example, as a coherent perceptual object; but also as a spatial arrangement of clearly defined parts: four legs and a top. Hence, perceptual units exist at many levels: at the level of whole objects, at the level of parts, and possibly smaller parts nested within larger ones" (Singh et al, 2001, p. 402). II. INTRODUCTION The extent to which Gestalt laws play a role in and help to clarify the overall understanding of visual perception and its relation to part-based and surface-based distinction allows one to better realize how the minds eye sorts the information it receives depending upon how and what it sees (Grill-Spector et al, 2004). The series of Gestalt laws begins with the law of pragnanz, which explains why the human mind feels obligated to perceive an entity as a whole being even if it is comprised of myriad segments. An ...
