Evolución de la pragmática en un caso de afasia de Broca severa

Though it is usual to speak about pragmatics of the speakers with brain damage, there are few detailed and rigorous analyses of the linguistic real production of such speakers. In this paper we present a model of pragmatic analysis from several transcriptions of a speaker with Broca aphasia by registered quantitatively information recounted to the index of conversational participation, to the type of interventions, and to the type of speech acts. There are identified as specific categories of the aphasic speech the editing tasks: draft acts, propositional acts, and activators of inferences acts (interjections and locutive acts), that overexploit other pragmatics cathegories as the Grice's implicatures or the inferencial meaning. The data belong to the corpus PerLA (perception, language and aphasia), integrated by conversational recordings of aphasic speakers. The evolution of the aphasic speaker demonstrates a clear increase of the lexical and grammatical skills, close to a showy reduction of conversational participation index. Usual speech therapy, worried by the recovery of the grammar, has to incorporate a real and effective consideration of the linguistic pragmatic elements, so that the lexical and morphosyntactic rehabilitation is not realized with the lost of the communicative efficiency of the speaker. For that, it will be necessary that the pragmatic evaluation be rigorous and detailed.
