La sintassi dialogica nei dialoghi tra logopedista e paziente afasico. Risonanza e diatassi in un corpus di 12 dialoghi

This work is a first attempt to analyze the conversations among a speech therapist and an aphasic patient in the light of the theoretical frame of dialogic syntax. The analysis of a corpus of 12 dialogues (6 dialogues among a speech therapist and an agrammatic aphasic, 6 dialogues involving a fluent aphasic) has shown that the participants, both strongly engaged in the conversation, co-construct the dialogue activating affinities across utterances (“resonances”, in dialogic syntax terminology). There have been recognized resonances derived from linguistic structures at all levels: lexical resonances, resonances on the diatactic frame, on the sentence level, across different dialogic turns. As the analysis of the data shows, agrammatic aphasics have a preference for resonances of content words, while fluent aphasics prefer structural resonances (total resonances, sentence resonances, resonances in the diatactic frame and function word resonances).
