We tested the effects of using a prosthesis for substitution of vision with audition (PSVA) on sensitivity to the Ponzo illusion. The effects of visual experience on the susceptibility to this illusion were also assessed. In one experiment, both early-blind and blindfolded sighted volunteers used the PSVA to explore several variants of the Ponzo illusion as well as control stimuli. No effects of the illusion were observed. The results indicate that subjects focused their attention on the two…

Vertical-horizontal illusion present for sighted but not early blind humans using auditory substitution of vision
TLDR
The absence of the illusion effect in early blind subjects suggests that the sensory experience influences the nature of perception and that the visual experience plays a crucial role in the vertical-horizontal illusion, in accordance with the size-constancy scaling theory.
Vision substitution and depth perception: Early blind subjects experience visual perspective through their ears
TLDR
The results suggest the possibility to compensate for some effects of early and long-lasting blindness by providing visual-like experience via SS through a visual-to-auditory SS system.
Learning to Perceive with a Visuo — Auditory Substitution System: Localisation and Object Recognition with ‘The Voice’
TLDR
The results showed that participants, through sensorimotor interactions with the perceptual scene while using the hand-held camera, were able to make use of the auditory stimulation to obtain the information necessary for locomotor guidance, localisation, and pointing, as well as for object recognition.
Generalized learning of visual-to-auditory substitution in sighted individuals
Looking into Task-Specific Activation Using a Prosthesis Substituting Vision with Audition
TLDR
FMRI induced a similar recruitment of frontoparietal brain areas in blindfolded sighted subjects as the corresponding tasks using the same stimuli in the same subjects in vision and observed a similar preference of the right superior parietal lobule for spatial localization over orientation processing in both sensory modalities.
The role of visual experience for the neural basis of spatial cognition
Pattern recognition using a device substituting audition for vision in blindfolded sighted subjects
Looking into brain activation using a sensory substitution prosthesis : seeing with sound
TLDR
This PhD thesis aimed to study possible behavioral and cerebral adjustments in sensory function when using sensory substitution to provide visual percepts in sighted people studied blindfolded and to investigate the neural correlates of face perception through sensory substitution of vision in early blind subjects.
Visualizing sounds: training-induced plasticity with a visual-to-auditory conversion device
TLDR
This study revealed that, after training, when asked to identify sounds, processes shared with vision were involved, as participants’ performance in sound identification was influenced by the simultaneously presented visual distractors.
The Implications of Brain Plasticity and Task Selectivity for Visual Rehabilitation of Blind and Visually Impaired Individuals
TLDR
The impact of invasive and noninvasive forms of artificial vision on brain organization with a special emphasis on sensory substitution devices is discussed and the implications for the visual rehabilitation of congenitally and late blind and partially sighted individuals while applying insights from neuroimaging and psychophysics are discussed.

Auditory coding of visual patterns for the blind.
TLDR
Simple pattern recognition is possible with a fairly natural vision-to-audition coding scheme, given the possibility for the subjects to have sensory--motor interactions while using the device.
Production and Interpretation of Perspective Drawings by Blind and Sighted People
TLDR
The results suggested that congenitally blind people may benefit from haptic exposure to raised-line configurations representing geometric perspective, especially for drawings of the board at the vertical orientation.
Auditory substitution of vision: pattern recognition by the blind
Pattern recognition in a computer environment was investigated in 6 early blind and 6 blindfolded sighted subjects using auditory substitution of vision. Subjects had to scan visual patterns…
Improved auditory spatial tuning in blind humans
TLDR
Comparisons of behavioural and electrophysiological indices of spatial tuning within central and peripheral auditory space in congenitally blind and normally sighted but blindfolded adults test the hypothesis that the effects of visual deprivation might be more pronounced for processing peripheral sounds.
Occipital Activation by Pattern Recognition in the Early Blind Using Auditory Substitution for Vision
TLDR
The results suggest that activity of the extrastriate visual cortex of early blind subjects can be modulated and bring additional evidence that early visual deprivation leads to cross-modal cerebral reorganization.

An experiment designed to measure Ss’ ability to detect small targets using self-generated sonar signals revealed that a group of six Ss blind from birth were significantly (.05 level) superior to…
Touch, representation, and blindness
Psychological studies of touch and blindness have been fraught with controversy. Within this field there remains an important theoretical divide. Many researchers have taken a cognitive approach to…
Early-blind human subjects localize sound sources better than sighted subjects
TLDR
The results resolve a long-standing controversy in that they provide behavioural evidence that totally blind individuals have better auditory ability than sighted subjects, enabling them to compensate for their loss of vision.
