The employee, Mr Taylor, is profoundly and prelingually deaf. |
In the 1970s, Helen Neville, a cognitive neuroscientist, showed that in prelingually deaf people the auditory parts of the brain had not atrophied. |
They can be used effectively by both prelingually and postlingually deafened children and adults. |
We believe that the best method for prelingually deaf and early-deafened children is Sign language, their natural language and the one they learn most easily, comfortably, and naturally. |
