The extent of visual deficit and auditory spatial compensation: evidence from self-positioning from auditory cues

Blindfolded sighted, myopic, amblyopic, adventitiously blind and congenitally blind humans performed a self-positioning task during which they were stimulated only by auditory cues. Results showed that visually deprived subjects used auditory cues to position themselves in their environment with a greater accuracy than normal-sighted subjects. In addition, the magnitude of auditory spatial compensation was found to be strongly related to the extent of the visual deficit.
