Étude de la cohérence discursive dans la relation de soin à travers les emplois fonctionnels de mais ; Study of discursive coherence in the care relationship through the functional uses of but

The study focuses on the use of discursive coherence marker but examined in care context. In the framework of DECLICS project, we focused on the functional distribution of but according to the role of the speaker (doctors vs therapists). Based on scientific literature, three macro-functions of but (interlocutive-interactional, logical-argumentative and logical-semantic) are broken down into 17 types, 16 of which are present in the DECLICS2016 corpus. With the systematic account of the 122 occurrences of but present in the corpus we study the quantitative frequency of comparative use between doctors and therapists. The quantitative results indicate that the doctors employ more but than therapists do, regardless of their respective hospital service. With a qualitative analysis, we reveal the interactional mechanisms during medical versus clinical therapeutic interviews, by determining the preponderant, secondary and tertiary functions assignable to each of the 122 occurrences of but. Of these 122 occurrences, 32 correspond to a single predominant function, 80 correspond to a bi-functionality of the marker and 10 to a tri-functionality. The results show that the interactional and semantic macro-functions allow the distinction of the roles of caregivers, and we observe a link between the use of the preponderant argumentative function and the secondary logical-semantic function of circumstantial type. The results made it possible to extract two patterns of use from the tri-functionality of but, mainly used by therapists. This study shows that doctors use but to mark logical-argumentative operations while therapists use but for an interactional purpose. ; L’étude porte sur les emplois du marqueur de cohérence discursive mais étudié en contexte de soin.
