{"pk":28489,"title":"Evidence of error-driven cross-situational word learning","subtitle":null,"abstract":"One powerful way children can learn word meanings is viacross-situational learning, the ability to discern consistentword-referent mappings from a series of ambiguous scenes andutterances. Various computational accounts of word learninghave been proposed, with mechanisms ranging from storingand testing a single hypothesized referent for each word, totracking multiple graded associations and selectively strength-ening some of them. Nearly all word learning models as-sume storage of some feasible word-referent mappings fromeach situation, resulting in a degree of learning proportionalto the number of co-occurrences. While these accumulativemodels would generally predict that incorrect co-occurrenceswould slow learning, recent empirical work suggests these ac-counts are incomplete: paradoxically, giving learners incorrectmappings early in training was found to boost performance(Fitneva & Christiansen, 2015). We test this finding’s general-ity in a new experiment with more items, consider system- anditem-level explanations, and find that a model with error-drivenlearning best accounts for this benefit of initially-inaccuratepairings.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"cross-situational word learning; error-driven asso-ciative learning model; word learning;"}],"section":"Papers with Oral Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7433c1bp","frozenauthors":[{"first_name":"Chris","middle_name":"","last_name":"Grimmick","name_suffix":"","institution":"New York University","department":""},{"first_name":"Todd","middle_name":"","last_name":"Gureckis","name_suffix":"","institution":"New York University","department":""},{"first_name":"George","middle_name":"","last_name":"Kachergis","name_suffix":"","institution":"Stanford University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28489/galley/18360/download/"}]}
