When one speaker's broccoli is another speaker's cauliflower: The real-time processing of multiple speaker vocabularies

Once interlocutors settle on a specific label in conversation, they tend to maintain the linguisticprecedent and reuse the same label (i.e. they become lexically entrained). This helps to facilitatecomprehension, with listeners identifying referents more quickly when repeated labels are usedcompared to new labels. In the current study, we looked at whether listeners are additionallysensitive to repeated infelicitous labels (Experiment 1), as when non-native speakers, forexample, overgeneralise a term (e.g. identifying a chair asthe chair with tires). In addition, weinvestigated the extent to which listeners’expectations of incorrect labels are influenced byknowledge of community speaking patterns, testing whether listeners could disregard recentlyencountered lexical errors from a non-native speaker as possible labels when processing anative speaker, who should not be expected to produce such errors (Experiment 2). Our resultsprovide no evidence that listeners were able to take into account speaker information
