This study looked into the socio-pragmatic competence of doctors using an L2 on the workfloor. L2-doctors' use of modification when communicating with patients and colleagues, and the declarative and procedural knowledge underlying their pragmatic competence was investigated. The study was performed in six European countries (Belgium, Denmark, Germany, Italy and Sweden) and also included a control group of L1-doctors from each country. This project was funded with support from the European Commission.
