Book excerpt: Excerpt from The Effect of Illumination on Peripheral Vision Table III has been selected as fairly representative of the results obtained with the white background and projection ground. It shows the general trend of the colors. With this background, however, there is greater variability in the observers, and also in the results for a single Observer, than with the other two backgrounds. Because Of this variability, special additional tables IV - VIII have been prepared, which represent respectively the results from red, orange, orange yellow, yellow, and yellow-green, for all the Observers. (1) Red is fairly constant, changing only slightly in the direction of yellow; (2) orange is almost as constant, but shifts some what toward red; (3) orange - yellow changes also toward red, though it only occasionally shifts beyond orange; (4) yellow soon loses its decidedly greenish cast and changes in the direc tion Of red; it almost never, however, shows a shift beyond orange; for G and B it is practically constant, and for the other observers it shifts generally only to orange-yellow; 5) yellow-green passes through greenish yellow and yellow to orange-yellow; for B it then shifts almost to orange; for F it becomes even more reddish; for the others (d, G, and R) it practically remains slightly on the yellow side of orange yellow; (6) green shifts through yellowish green, yellow green, and greenish yellow: to yellow; it is then usually color less, but is sporadically seen as orange-yellow, orange, or a color between orange and orange-red 7)blue - green changes to green ish blue or blue; it is even occasionally seen on the periphery as bluish green; (8) blue is fairly constant; (9) violet becomes blue for all except F, for whom it is sometimes violet; (io) purple likewise becomes blue for all except F, for Whom it is544.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Diseases of the Eye and Ophthalmoscopy: A Handbook for Physicians and Students These three functions of the eye, acuteness of vision, light-sense, and color-sense, are to be tested both directly (at the center) and indirectly (at the periphery). This examination of the extent of the visual field or for any gaps in it, is of distinct importance; the method employed is called Perimetry. Finally, the harmony of action in both eyes must be tested monocular ana' binocular vision; and all defects therein must be noted.

Download or read book Vision written by David Marr and published by MIT Press. This book was released on 2010-07-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Download or read book Purkinje s Vision written by Nicholas J. Wade and published by Psychology Press. This book was released on 2001-04-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life of Jan Evangelista Purkinje (1787-1869) has fascinated students from many disciplines. Histologists marvel at his early descriptions of cells; physiologists admire his attempts to relate structure to function; pharmacologists view in awe his heroic experiments on self-administered drugs; forensic scientists acknowledge his role in the use of fingerprints for identification; and Czech patriots salute his awakening of pride in their nation. Yet all these achievements followed his initial enquiries into vision. It is this psychological dimension that fostered this collaboration. As the title suggests, the present volume is bifocal. In the narrow sense it refers to Purkinje's studies of vision, but in its broader view it concerns Purkinje's anticipation of neuroscience. Purkinje provided evidence to support both its cellular and its conceptual base. At the cellular level his acute vision is immortalized within our bodies. At the conceptual level, he sought to relate subjective phenomena to their objective underpinnings--to link psychology to physiology. Vision provides a bond that unites psychology and physiology, and it is this bond that was strengthened by Purkinje's enquiries. The authors have tried to provide a context in which Purkinje's descriptions of visual phenomena can be placed. In some cases this exposes clear precursors of research for which Purkinje has been credited. In others, there was nothing to suggest the phenomena that he exposed. The book translates Purkinje's initial masterpiece on subjective vision and places it in the context of emerging views of neuroscience.
