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.
