Approche clinique et analytlque de l’aphasie au niveau de la coherence : analyse logico-semantique de l’aphasie

الملخص EN

Having two types of parameters, one linguistic and the other pragmatic, our grid of aphasia analysis is based on the neo-khalilien linguistic concepts, namely the semiologico-grammatical and the logico-semantic (communications!) analyses The results of our clinical investigation on throe eases of aphasia (two of Broca and one of Wernicke) at the lexical and Icxcmatic levels has allowed to reveal that Broca aphasia is an impairment in the process of the incremential variation governing the construction of generating patterns (schemes) which influences the grammatical cohesion , while the Wernicke aphasia is due to a disfunction in the processus of the root (ratine) (semiological analysis), which influences negatively the logico-semantic principle (coherence) at a global level (that of the discourse).
