RESUMO:

Recent studies in computational psychiatry (Mota et al., 2012, Mota et al., 2014, Mota et al., in preparation) indicate significant structural differences between the speech of psychotic and healthy subjects. Graph analysis of these subjects’ autobiographic reports allow the quantification of psychotic speech symptoms, marked by poor, disconnected and repetitive speech. In the 1970’s, Julian Jaynes proposed that psychosis was socially prevalent until around 1,000 BC. This conjecture was first tested by Diuk et al. (2012), who used Latent Semantic Analysis to assess the semantic similarity to the introspection concept across Judeo-Christian and Greco-Roman texts from the first millenium BC. In this perspective, we seek to investigate this hypothesis proceeding graph analysis of 448 texts across history, from 3,000 BC to 2,010 AC. Graph measures of six different cultures of Afro-Eurasia (Syro-Mesopotamian, Egyptian, Hindu, Persian, Judeo-Christian, Greek-Roman) and three more recent literary categories (Medieval, Modern, and Contemporary) reveal a clear pattern: While lexical diversity and connectivity increase, recurrence decreases. These findings are compatible with the notion that psychosis is an early trait of our species.
