|TITLE: A survey of some major contemporary
findings on haptic perception|

research on touch began during the 19thy century with psychophysical
studies on cutaneous discriminations, there are still much less studies
on haptics than on vision or audition. However, the new technologies
now available have allowed a considerable development of our knowledge
on haptic functioning during the last two decades. In this survey,
I will evoke some major findings concerning the activation of the
“visual” cortex by haptic stimulation in blind and sighted people,
the specific modes of processing information in haptics (role of movement
and exploratory procedures, role of gravity and force cues, etc),
and the characteristics of visual-haptic crossmodal coordination.
These findings will be discussed in the light of some of their applications
to education, blindness, medical and general ergonomy, etc.
Biography of Pr. Yvette Hatwell: Yvette Hatwell
is now emeritus professor of psychology at the University Pierre
Mendès-France in Grenoble (France). She studied psychology
in Paris and was then researcher at the Centre National de la Recherche
Scientifique (Laboratory of Experimental Psychology in Paris and
Institut National des Jeunes Aveugles). In 1964, she became Assistant
Professor at the University of Paris and, in 1968, she moved as
professor of psychology at the University of Geneva, in Switzerland,
in the department directed by professor Jean Piaget. Finally, she
established (1973) as professor at the University Pierre Mendès-France
in Grenoble where she created and directed during 15 years a research
centre in experimental and cognitive psychology (Laboratoire de
Psychologie Expérimentale, named today Laboratoire de Psychologie
Her research concerns haptic perception in blind and blindfolded
sighted children and adults. More specifically, she studied first
the effects of early and permanent visual deprivation on the cognitive
development of children and young adults. Then, Yvette Hatwell
worked on the characteristics and the development of haptic perception
and visuo-haptic intermodal coordination in children and young
adults. Her experimental observations are published in a number
of articles, books and book chapters, and are summarized in the
following recent comprehensive books:
