Word deafness10
  • It is yet unclear whether auditory agnosia (also called general auditory agnosia) is a combination of milder disorders, such auditory verbal agnosia (pure word deafness), non-verbal auditory agnosia, amusia and word-meaning deafness, or a mild case of the more severe disorder, cerebral deafness. (wikipedia.org)
  • This is called verbal auditory agnosia or pure word deafness. (wikipedia.org)
  • As of 2014[update], 203 patients with auditory perceptual deficits due to CNS damage were reported in the medical literature, of which 183 diagnosed with general auditory agnosia or word deafness, 34 with cerebral deafness, 51 with non-verbal auditory agnosia-amusia and 8 word meaning deafness (for a list of patients see). (wikipedia.org)
  • Based on this case study, as well as other aphasic patients, Lichtheim proposed that the language reception center receives afferents from upstream auditory and visual word recognition centers, and that damage to these regions results in word deafness or word blindness (i.e., alexia), respectively. (wikipedia.org)
  • The analysis of pure word deafness (PWD) suggests that speech perception, construed as the integration of acoustic information to yield representations that enter into the linguistic computational system, (i) is separable in a modular sense from other aspects of auditory cognition and (ii) is mediated by the posterior superior temporal cortex in both hemispheres. (nyu.edu)
