Developmental aspects of sensory substitution.
Research involving the provision of an artificial intersensory substitute--the SonicguideTM--is reported. Subjects were congenitally blind infants and young children. In a search task requiring distally appropriate responses, results indicated that younger subjects showed a more rapid sensitivity to the spatial information provided by the device. The implications of these developmental differences for intersensory substitutability are discussed.
