Book Description
This volume on Visual Psychophysics documents the current status of research aimed toward understanding the intricacies of the visual mechanism and its laws of operation in intact human perceivers. As can be seen from the list of contributors, the problems of vision engage the interest and experimental ingenuity of investi gators from a variety of disciplines. Thus we find authors affiliated with depart ments of biology, medical and physiological physics, ophthalmology, physics, physiology and anatomy, psychology, laboratories of neurophysiology, medical clinics, schools of optometry, visual and othcr types of research institutes. A continuing interplay between psychophysical studies and physiological work is everywhere evident. As more information about the physiological basis of vision accumulates, and new studies and analyses of receptor photochemistry and the neurophysiology of retina and brain appear, psychophysical studies of the intact organism become more sharply focused, sometimes more complex, and often more specialized. Technological advances have increased the variety and precision of the stimulus controls, and advances in measurement techniques have reopened old problems and stimulated the investigation of new ones. In some cases, new concepts are being drawn in to help further our under standing of the laws by which the visual mechanism operates; in other cases, ideas enunciated long ago have been reevaluated, developed more fully, and reified in terms of converging evidence from both psychophysical experiments and unit recordings from visual cells.

Book Description
A common human factors recommendation states that, for good target visibility, the area surrounding a display should not be brighter than the background area within the display. However, this recommendation must often be violated in applications where the surround brightness cannot be adequately controlled (e.g. in an airplane cockpit) and/or display technique limitations prevent use of high brightness backgrounds (e.g. with cathode ray tubes). This literature review was undertaken to see what has been discovered thus far concerning the effects on target visibility of specific parameters of a surround-to-background. Well over 100 documents were reviewed. Seventy-five annotated references to the more pertinent documents are contained in this report. Quantitative effects of pertinent parameters have been studied by numerous investigators. Results of studies using extended surrounds, rather than point sources, have not been sufficiently comprehensive or consistent to support quantitative generalizations in this area. Attempts have been made by Holladay and by Moon and Spencer to make quantitative predictions for the extended surround case on the basis of the more extensive body of data dealing with point source effects. However, several of the findings upon which their formulas are based have been contradicted by other findings cited in this report. (Author).

Book Description
Sensory Processes: The New Psychophysics describes, summarizes, and theorizes on the application of psychophysics to the study of sensory processes. This book deals with significant issues in sensory psychology, which is mainly by treating sensory dimensions and attributes as measurable quantities. Organized into seven chapters, this book starts with an overview of the fundamental methods for evaluating the magnitudes of sensation with emphasis direct scaling methods. This text then explains the advantages of direct scaling procedures in providing psychophysical and sensory-physical information. Other chapters consider the parameters of temporal and spatial distribution of the stimulus. This book discusses as well the other significant variables that determine sensitivity, particularly compositional variables that refer to wavelength and frequency of light and sound. The final chapter deals with several persistent issues and unresolved questions in the realm of sensory scaling. Sensory psychologists, sensory scientists, researchers, and graduate students will find this book useful.

Book Description
In the last ten years the neuroscience of language has matured as a field. Ten years ago, neuroimaging was just being explored for neurolinguistic questions, whereas today it constitutes a routine component. At the same time there have been significant developments in linguistic and psychological theory that speak to the neuroscience of language. This book consolidates those advances into a single reference. The Handbook of the Neuroscience of Language provides a comprehensive overview of this field. Divided into five sections, section one discusses methods and techniques including clinical assessment approaches, methods of mapping the human brain, and a theoretical framework for interpreting the multiple levels of neural organization that contribute to language comprehension. Section two discusses the impact imaging techniques (PET, fMRI, ERPs, electrical stimulation of language cortex, TMS) have made to language research. Section three discusses experimental approaches to the field, including disorders at different language levels in reading as well as writing and number processing. Additionally, chapters here present computational models, discuss the role of mirror systems for language, and cover brain lateralization with respect to language. Part four focuses on language in special populations, in various disease processes, and in developmental disorders. The book ends with a listing of resources in the neuroscience of language and a glossary of items and concepts to help the novice become acquainted with the field. Editors Stemmer & Whitaker prepared this book to reflect recent developments in neurolinguistics, moving the book squarely into the cognitive neuroscience of language and capturing the developments in the field over the past 7 years. - History section focuses on topics that play a current role in neurolinguistics research, aphasia syndromes, and lesion analysis - Includes section on neuroimaging to reflect the dramatic changes in methodology over the past decade - Experimental and clinical section reflects recent developments in the field

Book Description
Addresses the fundamental principles of visual perception and map symbolism and critically examines the assumptions behind the theories of psychophysical testing and cartographic communication. This revised and expanded edition includes new sections on the relationship between cartography and art, and the distinction between knowledge and skill.
