Abstract

Similarly to sighted people, individuals congenitally affected by a severe visual impairment can maintain and mentally manipulate spatial information about tactile stimuli [Vecchi, T., Cattaneo, Z., Monegato, M., Pece, A., Cornoldi, C., Pietrini, P., 2006. Why Cyclops could not compete with Ulysses: monocular vision and mental images. NeuroReport 17, 723-726]. The aim of the present study was to assess whether the onset timing of a severe (but not total) sight loss may influence spatial imagery abilities based on haptic input. To this purpose, a group of late severe visually impaired people and a matched group of normally sighted participants (all blindfolded) were presented with an imagery task requiring to memorize and retrieve a number of locations presented on tactile matrices. Results indicate that a severe visual deficit occurring later in life significantly impairs spatial imagery abilities to a greater extent than in the case of congenital blindness, probably as a consequence of a modest development of specific compensatory mechanisms associated with congenital deficits
