The main features of spoken language are at present well known to scholars, owing to the many corpora in existance nowadays. As regards some language pathologies, however, this does not seem to have had a significant effect on the analysis of the linguistic productions of patients affected by language disorders. This appears to be the case for the symptoms of schizophrenia, which, although identified by the use of certain linguistic phenomena, are mostly studied and classified according only to the report of the analyst and / or to the written production of patients. A major research gap in this specific literature is therefore primarily to be found in the lack of attention paid to diamesic variation, whereas in delirious psychosis oral language and written language appear to be significantly different varieties, each of them requiring a targeted analysis which applies methodologies specifically developed for the particular object under study. We intend to show the peculiarities of this type of speech as they emerge from the analysis of a corpus of spoken pathological / schizophrenic Italian, in which the recording of 'perilinguistic' and 'paralinguistic' elements plays an important role. Following from some early analysis of dialogic materials from the same corpus, this paper will explore the use of deixis and in particular the mode of occurrence of deictic I / you, as well as the semantics of both temporal and spatial deixis.
