Abstract
This chapter provides a set of guidelines, known as the Johnstone Boundary Condition Model (JBCM), to model lexical repetition into a dialogic sphere while providing an analysis of two ways to conceptualize lexical repetition and its conversational functions. Drawing from the work on interpersonal coordination and social support, we examined data from 273 dyads (151 strangers, 122 friends) to analyze the action of two types of linguistic coordination, Language Style Matching (LSM) and Local Lexical Repetition (LLR), on perceived understanding. Our results suggest that each measure alone does not predict outcomes (at least in this context); instead both measures together produce increased perceptions of understanding, at least among friends discussing problems. More generally, LSM and LLR were found to be conceptually different and empirically distinct and when paired with the JBCM can provide researchers new ways to understand the boundaries of linguistic repetition and its functions.
