In particular, the first session concentrates on the construction of the clinical setting and the introduction of the program, its aims and the tools used; the patients are asked to introduce themselves and explain the communication difficulties they experience in their daily living. These interventions are videorecorded and then used in the last session to verify the progress made and compare the initial performance of each patient with the abilities acquired through the training program. General Communication Ability (Sessions 2, 3, 22 & 23): In these sessions, two in the early stages of the program and two at the end, the patients practice their communication abilities and test their overall pragmatic effectiveness using all the modalities that constitute communicative competence.

Material: Video-taped scenes and role playing. Extralinguistic Ability (Sessions 6 & 7): These sessions are concerned with rehabilitation and improving patients’ gestural abilities.
