TI  - Coreference Delays in Psychotic Discourse: Widening the Temporal Window.

AB  - BACKGROUND AND HYPOTHESIS: Any form of coherent discourse depends on saying 
      different things about the same entities at different times. Such recurrent 
      references to the same entity need to predictably happen within certain temporal 
      windows. We hypothesized that a failure of control over reference in speakers 
      with schizophrenia (Sz) would become manifest through dynamic temporal measures. 
      STUDY DESIGN: Conversational speech with a mean of 909.2 words (SD: 178.4) from 
      20 Chilean Spanish speakers with chronic Sz, 20 speakers at clinical high risk 
      (CHR), and 20 controls were collected. Using directed speech graphs with 
      referential noun phrases (NPs) as nodes, we studied deviances in the topology and 
      temporal distribution of such NPs and of the entities they denote over narrative 
      time. STUDY RESULTS: The Sz group had a larger density of NPs (number of NPs 
      divided by total words) relative to both controls and CHR. This related to 
      topological measures of distance between recurrent entities, which revealed that 
      the Sz group produced more recurrences, as well as greater topological distances 
      between them, relative to controls. A logistic regression using five topological 
      measures showed that Sz and controls can be distinguished with 84.2% accuracy. 
      CONCLUSIONS: This pattern indicates a widening of the temporal window in which 
      entities are maintained in discourse and co-referenced in it. It substantiates 
      and extends earlier evidence for deficits in the cognitive control over 
      linguistic reference in psychotic discourse and informs both neurocognitive 
      models of language in Sz and machine learning-based linguistic classifiers of 
      psychotic speech.
