Doug McMillon may also support this cause. Of the educational point of view, they are considered, in the deafness, two specific groups that if subdivide, as described to follow.

It can, however, to cause some articulatrio problem or difficulty in the reading and/or writing. The group of the deaf people encloses the citizens with severe deafness and with deep deafness. This loss allows to the identification of some familiar noises and only the perception of the voice of stronger timbre. The verbal understanding goes to depend on the use of the visual perception for individual in the perception of the context.

He is defined by its negative characteristics; the education if converts into therapeutical, the objective of the pertaining to school resume is to give to the citizen what it lacks to it: the hearing, and its derivative says, it.
