Duplicity Theory Of Vision

This book chronicles the development of three classic theories within vision research, from the 17th century to today, focusing on duplicity theory.

One of the most persistent controversies of modern science has dealt with human visual perception. It erupted in Germany during the 1860s as a dispute between physiologists Hermann von Helmholtz, Ewald Hering, and their schools. Well into the twentieth century these groups warred over the origins of our capacity to perceive space, over the retinal mechanisms that mediate color sensations, and over the role of mind, experience, and inference in vision. Here R. Steven Turner explores the impassioned exchanges of those rival schools, both to illuminate the clash of theory and to explore the larger role of controversy in the development of science. Controversy, he suggests, is constitutive of scientific change, and he uses the Helmholtz-Hering dispute to illustrate how polemics and tacit negotiation shape evolving theoretical stances. Turner focuses on the arguments and issues of the dispute, issues that ranged from the interpretation of color blindness and optical illusions to the therapeutic practices of clinical ophthalmology. As well, he focuses on the personalities, institutions, disciplinary structures, and methodological commitments that shaped the dispute, including the schools' rhetorical strategies. He explores the incommensurability of the protagonists' viewpoints and examines the reception of the theories and the changing fortunes of the schools. Finally, Turner traces the controversy into the twentieth century, where the issues continue to inform the study of vision today. Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Though psychology is a comparatively ‘younger’ subject as compared to allied subjects like Philosophy, Anthropology and Sociology, recent years have witnessed remarkable strides in its study. Indeed, writings on the subject have been both prodigious and prolific because of the enormous interest evinced by those interested in psychology and because human behaviour—both complex and simple—is such a fascinating subject for study and research. This accessible and student-friendly text shows the ‘what,’ ‘why’ and ‘how’ of human behaviour patterns. The text emphasizes controlled and systematic studies to explain such behavioural aspects as sensing, perceiving, modifications of human behaviour, memorizing, the recollection of past events, and affecting processes. The text is interspersed with many examples to illustrate the concepts discussed. The concepts are well-supported with experimental as well as observational facts. What’s more, the book acquaints the reader with the recent advances in the field of psychology. KEY FEATURES  Liberal use of examples to give a clear idea of the concept discussed.  Step-by-step analysis of various psychological facts to facilitate better understanding of the subject.  Presentation of new advances and discoveries in the field of various psychological processes.  Glossary of terms besides chapter-end exercises and summaries. Primarily intended as a text for undergraduate students of psychology, the book can also be profitably used by postgraduate students and all those who have an abiding interest in the study of human behaviour.

In attempting to understand and explain various behaviour, events, and phenomena in their field, psychologists have developed and enunciated an enormous number of ‘best guesses’ or theories concerning the phenomenon in question. Such theories involve speculations and statements that range on a potency continuum from ‘strong’ to ‘weak’. The term theory, itself, has been conceived of in various ways in the psychological literature. In the present dictionary, the strategy of lumping together all the various traditional descriptive labels regarding psychologists ‘best guesses’ under the single descriptive term theory has been adopted. The descriptive labels of principle, law, theory, model, paradigm, effect, hypothesis and doctrine are attached to many of the entries, and all such descriptive labels are subsumed under the umbrella term theory. The title of this dictionary emphasizes the term theory (implying both strong and weak best guesses) and is a way of indication, overall, the contents of this comprehensive dictionary in a parsimonious and felicitous fashion. The dictionary will contain approximately 2,000 terms covering the origination, development, and evolution of various psychological concepts, as well as the historical definition, analysis, and criticisms of psychological concepts. Terms and definitions are in English. *Contains over 2,000 terms covering the origination, development and evolution of various psychological concepts *Covers a wide span of theories, from auditory, cognitive tactile and visual to humor and imagery *An essential resource for psychologists needing a single-source quick reference

For forty years Hugh Davson's Physiology of the Eye has been regarded as the leading textbook in ophthalmology. This extensively revised and updated fifth edition maintains this reputation and presents the author's lifelong expertise to the student. The structure and content have been revised to keep abreast of current teaching and research interests, while maintaining the style and clarity of previous editions.

With more than three times as many defined entries, biographies, illustrations, and appendices than any other dictionary of psychology ever printed in the English language, Raymond Corsini's Dictionary of Psychology is indeed a landmark resource. The most comprehensive, up-to-date reference of its kind, the Dictionary also maintains a user-friendliness throughout. This combination ensures that it will serve as the definitive work for years to come. With a clear and functional design, and highly readable style, the Dictionary offers over 30,000 entries (including interdisciplinary terms and contemporary slang), more than 125 illustrations, as well as extensive cross-referencing of entries. Ten supportive appendices, such as the Greek Alphabet, Medical Prescription Terms, and biographies of more than 1,000 deceased contributors to psychology, further augment the Dictionary's usefulness. Over 100 psychologists as well as numerous physicians participated as consulting editors, and a dozen specialist consulting editors reviewed the material. Dr. Alan Auerbach, the American Psychological Association's de facto dictionary expert, served as the senior consulting editor. As a final check for comprehensiveness and accuracy, independent review editors were employed to re-examine, re-review, and re-approve every entry.
