In this paper we investigate the behavior patterns of Alzheimer patients and multihandicapped persons communicating with peers and therapists in an interaction situation. Communicative items were analyzed automatically and sorted into patterns. The results showed that despite their reported ‘linguistic’ disabilities, the patients not only played their role in the interaction, but were also able to lead the conversation and take initiatives. In spite of their vulnerability, both types of patients, particularly those with Alzheimer’s disease, exhibited the ability to integrate (...) new information and to get involved in the dialogue.

Les langages humains et animaux diffèrent-ils réellement? Quel est le statut des gestes face aux autres signes linguistiques? L'importance de la voix? Si l'individu éprouve un tel besoin de communiquer, on peut se demander si les définitions les plus répandues du langage permettent de comprendre ce phénomène dans sa complexité et son fonctionnement au sein des interactions.
