Available in PDF, EPUB and Kindle. Book excerpt: Despite decades of research, significant mysteries remain concerning two fundamental aspects of human visual processing: how we perceive moderately complex line shapes such as letters of the alphabet, and how peripheral vision differs from foveal vision. This dissertation comprises studies that address both these topics, using experiments with letter recognition and visual "crowding"--The deleterious influence of flanking objects on identification of a target. Letters are well-studied psychophysical stimuli that strike a balance between degenerate patterns such as Gabor patches or gratings, with more uncontrolled stimuli such as natural images. Letters contain distinct spatial features that are more straightforward to quantify than the characteristics of natural scenes, yet have a sufficient richness of information to probe the general-purpose mechanisms of object recognition. The last decade has seen a renewed interest in perception in the peripheral visual field, with a particular emphasis on the phenomenon of crowding. Many researchers acknowledge that this curious effect provides a unique window into the process of object recognition. Since there is such a marked difference between the periphery, where crowding is potent, and the fovea, where it is nearly absent, crowding sheds light on the dichotomy between visual processing in the high resolution fovea versus the information-limited periphery. Understanding crowding may illuminate general principles of biological visual processing.

Download or read book Laws of Seeing written by Wolfgang Metzger and published by MIT Press. This book was released on 2009-08-21 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first English translation of a classic work in vision science from 1936 by a leading figure in the Gestalt movement, covering topics that continue to be major issues in vision research today. This classic work in vision science, written by a leading figure in Germany's Gestalt movement in psychology and first published in 1936, addresses topics that remain of major interest to vision researchers today. Wolfgang Metzger's main argument, drawn from Gestalt theory, is that the objects we perceive in visual experience are not the objects themselves but perceptual effigies of those objects constructed by our brain according to natural rules. Gestalt concepts are currently being increasingly integrated into mainstream neuroscience by researchers proposing network processing beyond the classical receptive field. Metzger's discussion of such topics as ambiguous figures, hidden forms, camouflage, shadows and depth, and three-dimensional representations in paintings will interest anyone working in the field of vision and perception, including psychologists, biologists, neurophysiologists, and researchers in computational vision—and artists, designers, and philosophers. Each chapter is accompanied by compelling visual demonstrations of the phenomena described; the book includes 194 illustrations, drawn from visual science, art, and everyday experience, that invite readers to verify Metzger's observations for themselves. Today's researchers may find themselves pondering the intriguing question of what effect Metzger's theories might have had on vision research if Laws of Seeing and its treasure trove of perceptual observations had been available to the English-speaking world at the time of its writing.
Download or read book Sophie s World written by Jostein Gaarder and published by Farrar, Straus and Giroux. This book was released on 2007-03-20 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.

Download or read book Murder Among Friends written by Candace Fleming and published by Anne Schwartz Books. This book was released on 2022-03-29 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did two teenagers brutally murder an innocent child...and why? And how did their brilliant lawyer save them from the death penalty in 1920s Chicago? Written by a prolific master of narrative nonfiction, this is a compulsively readable true-crime story based on an event dubbed the "crime of the century." In 1924, eighteen-year-old college students Nathan Leopold and Richard Loeb made a decision: they would commit the perfect crime by kidnapping and murdering a child they both knew. But they made one crucial error: as they were disposing of the body of young Bobby Franks, whom they had bludgeoned to death, Nathan's eyeglasses fell from his jacket pocket. Multi-award-winning author Candace Fleming depicts every twist and turn of this harrowing case--how two wealthy, brilliant young men planned and committed what became known as the crime of the century, how they were caught, why they confessed, and how the renowned criminal defense attorney Clarence Darrow enabled them to avoid the death penalty. Following on the success of such books as The Rise and Fall of Charles Lindbergh and The Family Romanov, this acclaimed nonfiction writer brings to heart-stopping life one of the most notorious crimes in our country's history.
