Discourse attention during utterance planning affects referential form choice

Abstract

Abstract:An unstudied source of linguistic variation is the use of discourse-appropriate language. Sometimes individuals use linguistic devices (anaphors, connectors) to connect utterances to the discourse context, and sometimes not. We asked how this variation is related to utterance planning, using eyetracking with a narrative production task. Participants saw picture pairs depicting two events. They heard a description of the first event (Context picture), then added to the story by describing the second event (Target picture). We found that one group of participants produced utterances that connected with the discourse context (Context-Users), using pronouns/zeros and connectors (and/then) as appropriate, while another group consistently used definite NP descriptions and virtually no connectors (Context-Ignorers). Eyetracking measures reflected utterance planning within a discourse context: all participants shifted their attention from the Context picture to the Target picture throughout a trial. We also observed group differences: Context-Users directed their attention in a more systematic way than Context-Ignorers. At trial onset, Context-Users looked more at the Context picture than Context-Ignorers. Right before speaking, they looked more at the Target picture than Context-Ignorers. The Context-Users also had shorter latency to begin speaking. This study provides a first step toward characterizing individual differences in terms of utterance planning.
