The influence of dialogue context on the relationship between language production and comprehension
Kaitlyn Litcofsky1, Janet van Hell1; 1Pennsylvania State University
Language production and comprehension are typically studied separately. Yet, both are engaged in dialogue, where one individual expresses their thoughts through speech and the other listens to that output for comprehension. This pattern reverses continually, and every speaker is also a listener. The Interactive Alignment model (Pickering & Garrod, 2004) claims that production and comprehension are linked across interlocutors. Here, we examined how production and comprehension are linked within an individual, and how dialogue context impacts that relationship, using electrophysiological and behavioral methods. Alignment with an interlocutor should strengthen the alignment between production and comprehension within the individual, as compared to a monologue context. Participants completed two cross-modal syntactic priming tasks of active/passive sentences: production-to-comprehension in which they listened to sentences while EEG (Electroencephalography) was recorded (measure: Event-Related Potentials, ERPs) and comprehension-to-production in which they described simple pictures (measures: syntactic choice, average reaction time, average syllable duration). In dialogue, participants interacted with a confederate. In monologue, participants completed the task alone. For production-to-comprehension, ERPs revealed a sustained N400 priming effect at the main verb of target passive sentences both in monologue and dialogue. For comprehension-to-production, priming of the proportion of passives produced was found both in monologue and dialogue. The similar patterns of cross-modal syntactic priming in production and comprehension observed within an individual suggest that there are shared mechanisms underlying these processes. Moreover, these basic mechanisms are manifested similarly in monologue and dialogue contexts.
