Speech often (always?) deteriorates for people with post-lingual deafness. This presumably occurs because of insufficient auditory feedback.

Given that people with Wernicke's aphasia cannot comprehend language, do they also experience speech deterioration (that is, speech becoming disjointed and/or ungrammatical) over time as a result of hearing themselves speak, but not understanding the sounds they produce?

  • Very interesting! I have never heard of such evolution of Wernicke's, but the suggestion totally makes sense. Btw, can you give some details of/links to the deterioration facts you refer to? – Ivan Kapitonov Feb 22 '15 at 21:25
  • @IvanKapitonov Details re: deterioration in people with post-lingual deafness? – fenceop Feb 22 '15 at 21:26
  • Oh yes! Sorry, I worded it awkwardly. – Ivan Kapitonov Feb 22 '15 at 21:48

    One paper that comes to mind is Waldstein (1990) [1]. I'll see if my prof can recommend other texts and I'll write an update later this week. [1] Waldstein, R. S. (1990).

    @fenceop Many questions are on-topic on several sites, but some sites will have people who are more experience on certain topics. There may be some psychologists here, but I think there would be more at the other site. – curiousdannii Feb 24 '15 at 21:16
