Abstract

Aim of the present meta-analysis of the experimental studies on deafness and communication is to compare, in terms of efficacy, the communicative methods currently used to teach deaf people to communicate. From the meta-analysis emerges that the sign languages and the bilinguism facilitate, more than the oralist and the mix methods, discourse comprehension in deaf people. Provided our considerations, which are supported by experimental data, we will present some statistical data according to which in Italy parents of deaf children choose for their sons schools that do not adopt the most effective communicative methods.
