Bruno Rocha, Tommaso Raso, Heliana Mello, Lucia Ferrari

• This paper focuses on information structure in the speech of individuals with schizophrenia, according to the theoretical framework found in the Language into Act Theory. A specific textual structure, called stanza, and its informational complexity, have been compared using two corpora: the C-ORAL-ESQ for pathological speech, and the C-ORAL-BRASIL for non-pathological speech. Firstly, we briefly explain the theory and the concept of stanza. Then, we explain in depth the methodology adopted for comparing pathological and non-pathological speech, using the two corpora. Additionally, we discuss the results found, part of which have statistical significance. Finally, we propose a first explanation of the results, focusing on cognitive and prosodic aspects that could provide insights for further research.
