© The Author(s) 2020. Interactional adjustment refers to people’s tendency to adjust, or adapt, their communication behavior in social interactions. In recent years, three distinctive approaches to this topic that have featured prominently in the Journal of Language and Social Psychology are communication accommodation theory (CAT), language style matching (LSM), and discursive psychology using conversation analysis (DPCA). In this article, we provide a review of these three approaches, highlighting what defines and distinguishes them, as well as what insights into interactional adjustment each offers. We draw out the connections and points of tensions between these approaches; in so doing, we identify future directions for research on interactional adjustment as a fundamental aspect of human communication, and in the study of language and social psychology.
