The power of vision: Calibration of auditory space after sight restoration from congenital cataracts

Early visual deprivation typically also results in impaired spatial
cognition in the other sensory modalities (e.g., audition). It has been
suggested that this happens because, since vision provides the most
accurate spatial information, it is also used as a reference for
calibrating space in the other sensory modalities during development. Here
we found that sight restoration after several years of early-onset visual
deprivation can lead to the development of more accurate and precise
auditory space perception. In two experiments we assessed auditory space
perception in individuals who suffered from congenital bilateral cataracts
and got surgically treated for sight restoration several years after
birth.
