{"pk":29652,"title":"Examining a developmental pathway of early word learning: From qualitative\ncharacteristics of parent speech, to sustained attention, to vocabulary size","subtitle":null,"abstract":"The quality of parent speech has been argued to impact child\nlanguage growth above and beyond quantity. One potential\nmechanism tying online experience to long-term vocabulary\ndevelopment is sustained attention to targets of parent speech.\nWe recruited thirty-five parent-toddler dyads to participate in\nfree toy play while wearing head-mounted eye trackers. Parent\nspeech was categorized based on its referential nature, syntax,\nand communicative intent. Parent referential speech positively\nrelated to both vocabulary size and online patterns of sustained\nattention. Speech categorized based on communicative intent\nalso showed relations with vocabulary size and sustained\nattention, but specific types of speech impacting each differed.\nThese results support the hypotheses that qualitative\ncharacteristics of parent speech relate to both long-term\nlanguage growth and online sustained attention and provide\ntentative evidence for the broader hypothesis that sustained\nattention is the mechanism tying online experience to long-\nterm language growth.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"eye-tracking; language input; eye-tracking;\nparent-child interaction; sustained attention; vocabulary size"}],"section":"Poster Session 1","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2p82d0sp","frozenauthors":[{"first_name":"Ryan","middle_name":"E.","last_name":"Peters","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Chen","middle_name":"","last_name":"Yu","name_suffix":"","institution":"Indiana University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29652/galley/19510/download/"}]}
