{"pk":27221,"title":"A Hebbian account of entrenchment and (over)-extension in language learning","subtitle":null,"abstract":"In production, frequently used words are preferentially\nextended to new, though related meanings. In comprehension,\nfrequent exposure to a word instead makes the learner\nconfident that all of the word’s legitimate uses have been\nexperienced, resulting in an entrenched form-meaning\nmapping between the word and its experienced meaning(s).\nThis results in a perception-production dissociation, where the\nforms speakers are most likely to map onto a novel meaning\nare precisely the forms that they believe can never be used\nthat way. At first glance, this result challenges the idea of\nbidirectional form-meaning mappings, assumed by all current\napproaches to linguistic theory. In this paper, we show that\nbidirectional form-meaning mappings are not in fact\nchallenged by this production-perception dissociation. We\nshow that the production-perception dissociation is expected\neven if learners of the lexicon acquire simple symmetrical\nform-meaning associations through simple Hebbian learning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Hebbian learning; word learning; mental lexicon"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1854n0jh","frozenauthors":[{"first_name":"Vsevolod","middle_name":"","last_name":"Kapatsinski","name_suffix":"","institution":"University of Oregon","department":""},{"first_name":"Zara","middle_name":"","last_name":"Harmon","name_suffix":"","institution":"University of Oregon","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/27221/galley/16857/download/"}]}
