Resumo:
The present dissertation is a theoretical-experimental study on language in schizophrenia, focusing on the usage of pronouns in written texts produced by native speakers of English and published on Reddit, considering in addition syntactic complexity at the sentential level. Schizophrenia is a mental disorder characterized by a set of heterogeneous dysfunctions, with language-malfunctioning being one of its main characteristics. In particular, misuse and misinterpretation of nominal expressions and syntactic-complexity reduction are linguistic hallmarks of schizophrenia. 78 texts (39 from Reddit users with self-declaration of schizophrenia and 39 from paired controls) were automatically collected, manually tagged and statistically compared. The tagging process was based on syntactic complexity at the sentential and nominal level. Between-group statistical comparisons showed significant differences, with the schizophrenic group exhibiting less non-anomalous sentential truncations (ellipsis) and more anomalous 3Person referential pronouns. This is in accordance with previous independent studies. Assuming human Grammar to be a computational apparatus of the cognitive system, we interpret the obtained results as suggesting that schizophrenia leads to reductions on meaning-building derivational grammatical processes.
