{"pk":27005,"title":"It’s all in your head: Effects of expertise on real-time accessto knowledge during written sentence processing","subtitle":null,"abstract":"Real-time sentence processing involves connecting linguistic inputwith knowledge. Here, we ask how variability in semantic memory(specific domain knowledge) may influence semantic access in real-time sentence processing. We recorded EEG while participantsmore/less knowledgeable about the narrative world of Harry Potter(HP) read sentences. In Experiment 1, all participants showed N400predictability effects for general-knowledge sentences, but onlythose with high HP knowledge showed predictability effects forsentences about Harry Potter. This effect was driven by graded brainresponses to predictable endings as a function of knowledge.Experiment 2 revealed greater semantic activation (inferred fromN400 effects) for HP items participants reported knowing. High-knowledge participants also showed greater semantic activation foritems they reported not knowing/remembering. These findingssuggest that amount and/or functional organization of knowledgehas real-time consequences on written sentence processing andimplicate implicit/partial access to domain knowledge for expertswhen information is not explicitly recalled.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"sentence processing; knowledge; ERPs;individual differences"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/78g262v8","frozenauthors":[{"first_name":"Melissa","middle_name":"","last_name":"Troyer","name_suffix":"","institution":"University of California, San Diego","department":""},{"first_name":"Marta","middle_name":"","last_name":"Kutas","name_suffix":"","institution":"University of California, San Diego","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/27005/galley/16641/download/"}]}
