Présentation de l'éditeur
Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of
"seeing" as the ability to generate internal mental representations that may contain visual details,
the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo
and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the
development and functioning of the human cognitive system. Drawing on behavioral and
neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition,
and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with
complete or profound visual impairment. They find that our brain does not need our eyes to
"see."
Cattaneo and Vecchi address critical questions of broad importance: the
relationship of visual perception to imagery and working memory and the extent to which mental
imagery depends on normal vision; the functional and neural relationships between vision and the
other senses; the specific aspects of the visual experience that are crucial to cognitive
development or specific cognitive mechanisms; and the extraordinary plasticity of the brain -- as
illustrated by the way that, in the blind, the visual cortex may be reorganized to support other
perceptual or cognitive funtions. In the absence of vision, the other senses work as functional
substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take
on the "tyranny of the visual," pointing to the importance of the other senses in
cognition.
