Abstract

This study analyzes written texts by patients diagnosed with schizophrenia within a creative writing task framework. Both lexical and grammatical structures were analyzed and quantified to find linguistic evidence, which allows the visualization of functional deterioration in self-monitoring abilities, fundamental in writing. To achieve this, we applied the Type and Token Ratio, and we evaluated the length of words and sentences; and, finally, we carried out a morphological parameterization to visualize the lexical repertoire by grammatical categories. The results obtained in the groups of participants with pathology show a poor performance in the indicators studied. This indicates that it is possible to propose an operable characterization of differential traits in the writing of people diagnosed with schizophrenia.
