Abstract

Lexical alignment refers to the adoption of one’s interlocutor’s lexical items. Accounts of the mechanisms underlying such lexical alignment differ (among other aspects) in the role assigned to addressee-centered behavior. In this study, we used a triadic communicative situation to test which factors may modulate the extent to which participants’ lexical alignment reflects addressee-centered behavior. Pairs of naïve participants played a picture matching game and received information about the order in which pictures were to be matched from a voice over headphones. On critical trials, participants did or did not hear a name for the picture to be matched next over headphones. Importantly, when the voice over headphones provided a name, it did not match the name that the interlocutor had previously used to describe the object. Participants overwhelmingly used the word that the voice over headphones provided. This result points to non-addressee-centered behavior and is discussed in terms of disrupting alignment with the interlocutor as well as in terms of establishing alignment with the voice over headphones. In addition, the type of picture (line drawing vs. tangram shape) independently modulated lexical alignment, such that participants showed more lexical alignment to their interlocutor for (more ambiguous) tangram shapes compared to line drawings. Overall, the results point to a rather large role for non-addressee-centered behavior during lexical alignment.

Highlights

During conversation, speakers tend to adopt a variety of aspects of their interlocutors’ linguistic and non-linguistic behavior
A number of different theoretical accounts have attempted to spell out the mechanisms that lead to lexical alignment in conversation (e.g., Brennan and Clark, 1996; Pickering and Garrod, 2004; Keysar, 2007)
This study investigated several factors that may affect the strength of lexical alignment to a specific conversation partner

Summary

Introduction

Speakers tend to adopt a variety of aspects of their interlocutors’ linguistic and non-linguistic behavior. Speakers may adopt their interlocutor’s syntactic structures (Branigan et al, 2000), lexical items (e.g., Brennan and Clark, 1996), description schemes (Garrod and Anderson, 1987), word pronunciation (Pardo, 2006), body posture (Chartrand and Bargh, 1999), etc. Such alignment of interlocutors is pervasive in communication (Wachsmuth et al, 2013) and has been suggested to contribute to communicative success (Pickering and Garrod, 2006). These accounts differ, among other things, in the extent to which utterances are assumed to be designed for a particular interlocutor
