This paper discusses some possibilities that the theory of translational norms may offer in connection with research into simultaneous interpreting. After a brief discussion of the concept of translational norms, the author explores how this concept may be useful in interpreting research in general. The author then proceeds to discuss and criticize the set-up of her own project on simultaneous interpreting and translation - especially how the progressive aspect was originally used as a focus of analysis. The author concludes by demonstrating how the theory of translational norms has been a useful methodological tool in the analysis of her data.
