The equidistance tendency is the tendency for objects or other inhomogeneities in the field-of-view to appear at the same distance as each other with the strength of this tendency being inversely related to directional separation. The evidence for the existence of the equidistance tendency and for its ability to modify the perceived depth resulting from size or stereoscopic cues is reviewed. The equidistance tendency is discussed as a disturbing factor in visual experimentation and as a necessary factor in the understanding of Emmert's law, the moon illusion, and similar phenomena. Several possible explanations for the equidistance tendency are evaluated in terms of the range of phenomena with which it is identified. (Author).
When most people think of space, they think of physical space. However, visual space concerns space as consciously experienced, and it is studied through subjective measures, such as asking people to use numbers to estimate perceived distances, areas, angles, or volumes. This book explores the mismatch between perception and physical reality, and describes the many factors that influence the perception of space including the meaning assigned to geometric concepts like distance, the judgment methods used to report the experience, the presence or absence of cues to depth, and the orientation of a stimulus with respect to point of view. The main theme of the text is that no single geometry describes visual space, but that the geometry of visual space depends upon the stimulus conditions and mental shifts in the subjective meaning of size and distance. In addition, The Geometries of Visual Space: *contains philosophical, mathematical, and psychophysical background material; *looks at synthetic approaches to space perception including work on hyperbolic, spherical, and Euclidean geometries; *presents a meta-analysis of studies that ask observers to directly estimate size, distance, area, angle, and volume; *looks at the size constancy literature in which observers are asked to adjust a comparison stimulus to match a variety of standards at different distances away; *discusses research that takes a multi-dimensional approach toward studying visual space; and *discusses how spatial experience is influenced by memory. While this book is primarily intended for scholars in perception, mathematical psychology, and psychophysics, it will also be accessible to a wider audience since it is written at a readable level. It will make a good graduate-level textbook on space perception.
According to Putnam to talk of “facts” without specifying the language to be used is to talk of nothing; “object” itself has many uses and as we creatively invent new uses of words “we find that we can speak of ‘objects’that were not ‘values of any variable’in 1 any language we previously spoke” . The notion of object becomes, then, like the notion of reference, a sort of open land, an unknown territory. The exploration of this land - pears to be constrained by use and invention. But, we may wonder, is it possible to guide invention and control use? In what way, in particular, is it possible, at the level of na- ral language, to link together program expressions and natural evolution? To give an answer to these onerous questions we should immediately point out that cognition (as well as natural language) has to be considered first of all as a peculiar fu- tion of active biosystems and that it results from complex interactions between the - ganism and its surroundings. “In the moment an organism perceives an object of wh- ever kind, it immediately begins to ‘interpret’this object in order to react properly to it . . . It is not necessary for the monkey to perceive the tree in itself. . . What counts is sur- 2 vival” .
This book provides an introduction to human visual perception suitable for readers studying or working in the fields of computer graphics and visualization, cognitive science, and visual neuroscience. It focuses on how computer graphics images are generated, rather than solely on the organization of the visual system itself; therefore, the text pro
The best example of filling-in involves the blind spot, a region of the retina devoid of photoreceptors. While this phenomenon is common in the visual domain, it is argued by contributors to this book that forms of filling-in also take place in other sensory modalities.
