Touch, Representation, and Blindness


Book Description

Psychological studies of touch and blindness have been fraught with controversy. Within this field there remains an important theoretical divide. Many researchers have taken a cognitive approach to the study of touch and blindness, relating these to higher order processes, such as memory and concept formation. Others adopt a theoretical perspective, arguing that it not necessary to consider the 'internal representation' of the stimuli, when investigating touch - thus people make use of information from the physical biomechanical properties of their limbs as they assess the physical properties of objects. In addition, psychologists differ in the relative importance they place on the modality of sensory stimulation for subsequent perceptual experiences. Some psychologists argue that touch can do many of the things that are accomplished by vision, and claim that the mode of sensory stimulation is not critically important for perception, arguing that much information can be obtained through non-visual modalities. Others suggest that there are important consequences of a lack of visual experience, arguing for the importance of multiple forms of sensory input for conceptual development. New to the Debates in Psychology series, Touch, Representation, and Blindness brings together the leading investigators in these areas, each presenting the evidence for their side of the debate. An introductory chapter sets the theoretical and historical stage for the debate, and a concluding chapter draws together the different views and ideas set forth by the contributors, summarizing and resolving the discussion.




Touch and Blindness


Book Description

Research on touch and blindness has undergone rapid transformation in recent years, with dramatic developments in technology designed to provide assistance to those who are blind, and advancements in robotics that demand haptic interfaces. Touch and Blindness approaches the study of the topic from the perspectives of psychological methodology and the most sophisticated, state-of-the-art techniques in neuroscience. This book, edited by well-known leaders in the field, is derived from the discussions presented by speakers at a conference held in 2002, and presents current research in the field. The book is arranged in a logical, disciplinary fashion, first discussing touch and blindness from a psychological perspective, followed by an examination from the perspective of neuroscience. Some specific topics include: *processing spatial information from touch and movement; *form, projection, and pictures for the blind; *neural substrate and visual and tactile object representations; and *the role of visual cortex in tactile processing. Touch and Blindness is ideal for researchers in psychology and neuroscience, medicine, and special education.




Psychology of Touch and Blindness


Book Description

This book reviews the considerable body of research that has been done to evaluate the touch skills of blind people. With an emphasis on cognitive and neuroscientific approaches, it encompasses a wide-ranging discussion of the theoretical issues in the field of touch perception and blindness. The volume includes chapters on sensory aspects of touch, perception in blind individuals, multimodal relations and their implications for instruction and development, and new technology, including sensory aids and virtual touch. A distinctive feature of the book is the inclusion of the practical applications of research in this area. A significant characteristic of research on touch and imagery in congenitally blind individuals is that it speaks to the basic nature of spatial imagery and the importance and necessity -- or lack thereof -- of specific visual sensory experience for the acquisition of knowledge about space, spatial layout, and picture perception. As such, the book will not only appeal to researchers and professionals with an interest in touch and blindness, but also to a wider audience of cognitive psychologists and cognitive neuroscientists working in the field of perception.




Blindness and Brain Plasticity in Navigation and Object Perception


Book Description

This book features chapters from cognitive and developmental psychologists, neurologists and neuroscientists, and rehabilitation specialists and educators. These groups do research in this area but generally do not collaborate. This book is an attempt to bring together the disparate threads of research into one volume.




Seeing with the Hands


Book Description

A literary, historical and philosophical discussion of attitudes to blindness by the sighted, and what the blind 'see'Why has there been a persistent fascination by the sighted, including philosophers, poets and the public, in what the blind 'see'? Is the experience of being blind, as Descartes declared, like 'seeing with the hands'? What happens on the rare occasions when surgery allows previously blind people to see for the very first time? And how did evidence from early experimental surgery inform those philosophical debates about vision and touch? These questions and others were prompted by a question that the Irish scientist, Molyneux, asked an English philosopher, Locke, in 1688, but which was to have implications for British empiricism, French sensationism, and the beginnings of psychology that outlasted the long tail of the Enlightenment. Through an unfolding historical and philosophical narrative the book follows up responses to this question in Britain and France, and considers it as an early articulation of sensory substitution, the substitution of one sense (touch) for another (vision). This concept has influenced attitudes towards blindness, and technologies for the blind and vision impaired, to this day.Key FeaturesUnfolds the history of 'blindness' from 17th century that shades into the beginnings of psychologyQuestions the assumed centrality of vision and the eye in Enlightenment philosophy and scienceTraces the core idea of 'sensory substitution' from hypothetical speculations in the 17th century to present day technologies for the blind and vision impaired




Touching for Knowing


Book Description

The dominance of vision is so strong in sighted people that touch is sometimes considered as a minor perceptual modality. However, touch is a powerful tool which contributes significantly to our knowledge of space and objects. Its intensive use by blind persons allows them to reach the same levels of knowledge and cognition as their sighted peers.In this book, specialized researchers present the recent state of knowledge about the cognitive functioning of touch. After an analysis of the neurophysiology and neuropsychology of touch, exploratory manual behaviors, intramodal haptic (tactual-kinesthetic) abilities and cross-modal visual-tactual coordination are examined in infants, children and adults, and in non-human primates. These studies concern both sighted and blind persons in order to know whether early visual deprivation modifies the modes of processing space and objects. The last section is devoted to the technical devices favoring the school and social integration of the young blind: Braille reading, use of raised maps and drawings, “sensory substitution” displays, and new technologies of communication adapted for the blind.
