{"pk":27202,"title":"The Influence of Speaker’s Gaze on Sentence Comprehension: An ERPInvestigation","subtitle":null,"abstract":"Behavioral studies demonstrate the influence of speakergaze in visually-situated spoken language comprehension.We present an ERP experiment examining the influence ofspeaker’s gaze congruency on listeners’ comprehension of ref-erential expressions related to a shared visual scene. Wedemonstrate that listeners exploit speakers’ gaze toward ob-jects in order to form sentence continuation expectations:Compared to a congruent gaze condition, we observe an in-creased N400 when (a) the lack of gaze (neutral) does not al-low for upcoming noun prediction, and (b) when the noun vi-olates gaze-driven expectations (incongruent). The later alsoresults in a late (sustained) positivity, reflecting the need to up-date the assumed situation model. We take the combinationof the N400 and late positivity as evidence that speaker gazeinfluences both lexical retrieval and integration processes, re-spectively (Brouwer et al., in press). Moreover, speaker gazeis interpreted as reflecting referential intentions (Staudte &Crocker, 2011).","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"ERP; N2; N400; late sustained positivity; gaze;prediction; referential expressions"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3f56z996","frozenauthors":[{"first_name":"Torsten","middle_name":"Kai","last_name":"Jachmann","name_suffix":"","institution":"Saarland University","department":""},{"first_name":"Heiner","middle_name":"","last_name":"Drenhaus","name_suffix":"","institution":"Saarland University","department":""},{"first_name":"Maria","middle_name":"","last_name":"Staudte","name_suffix":"","institution":"Saarland University","department":""},{"first_name":"Matthew","middle_name":"W.","last_name":"Crocker","name_suffix":"","institution":"Saarland University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27202/galley/16838/download/"}]}
