Discourse coherence - From psychology to linguistics and back again

Abstract : The present volume explores recent advances in modeling discourse processes, particularly new approaches aimed at understanding pathological language behavior specific to schizophrenia. In this work, we examine the modeling paradigm of formal semantics, which falls within the scope of both linguistics and logic while providing overlapping links with other fields such as philosophy of language and cognitive psychology. This volume is based on results presented during the series of workshops on (In)Coherence and Discourse organized by SLAM (Schizophrenia and Language: Analysis and Modeling), a project developed to systemize the study of pathological language processing by taking an overarching interdisciplinary approach combining psychology, linguistics, computer science and philosophy. The principle focus is on conversations produced by people with psychiatric disorders (such as schizophrenia and autism). The series of (In)Coherence of Discourse workshops hosted by the Loria were held in Nancy, France and include 33 presentations by lead researchers, young researchers and invited speakers. Our focus is on evaluating the heuristics of several formal approaches presented in the scientific literature aimed at explaining the incongruities and disturbances that characterize pathological discourse. We examine specifically the degree to which these formal approaches and experiments support traditional debates about discourse coherence and related cognitive processes. Based on a comprehensive evaluation of a range of works that have attempted to explain key disturbances such as disordered language and deficit in inferential skills, we show why some approaches are more relevant than others. Discourse coherence has traditionally been explored through discipline-specific research. We propose that considerable potential lies in approaching the question through a wider lens by considering perspectives across a range of disciplines; notably linguistics, computer science, philosophy and psychology. This volume underscores the importance and value of exploring this particularly complex issue within an interdisciplinary framework. In this introduction we begin by addressing the fundamental differences between current experimental and clinical approaches. By considering the underlying assumptions inherent in each, we show how both approaches fail to account for intentionality as an independent feature interaction dynamics. In the first section of this chapter, we show how modeling complex mental operations (including intentional states) through formal approaches to language can potentially compensate for this lack. In the second section, we describe several selected theories of linguistics and dedicate a section to those that have been applied to the study of schizophrenia. In the third and final section, we revisit the epistemological issues raised by the plurality of approaches to discourse coherence. We conclude with a more detailed presentation of the contributions in this volume.
