{"pk":27492,"title":"The acquisition of verb morphology in Polish and Finnish: Model and experiment","subtitle":null,"abstract":"Usage-based approaches suggest that language acquisition is a function of the statistical properties of the input. Wecompare predictions from neural network models with results of two elicited-production experiments on verb inflection withchildren in the morphologically complex languages Polish and Finnish. Three-layer neural networks were trained to produceperson/number-inflected present-tense verb forms in Polish and Finnish from phoneme representations of verb stems usingfrequency information from child-directed speech corpora. Simulated acquisition in both languages was affected by tokenfrequency and phonological neighbourhood density (PND) as well as an interaction such that low-frequency forms benefitedmore from PND than high-frequency forms. Suffix errors showed overgeneralisation and substitutions of low-frequency formswith higher-frequency forms. The model predictions are consistent with our empirical findings, except for the frequency XPND interaction. We discuss the experimental and simulated data and their implications.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/99c4f7vd","frozenauthors":[{"first_name":"Felix","middle_name":"","last_name":"Engelmann","name_suffix":"","institution":"University of Manchester","department":""},{"first_name":"Joanna","middle_name":"","last_name":"Kolak","name_suffix":"","institution":"University of Manchester","department":""},{"first_name":"Sonia","middle_name":"","last_name":"Granlund","name_suffix":"","institution":"University of Liverpool","department":""},{"first_name":"Ben","middle_name":"","last_name":"Ambridge","name_suffix":"","institution":"University of Liverpool","department":""},{"first_name":"Julian","middle_name":"","last_name":"Pine","name_suffix":"","institution":"University of Liverpool","department":""},{"first_name":"Anna","middle_name":"","last_name":"Theakston","name_suffix":"","institution":"University of Manchester","department":""},{"first_name":"Elena","middle_name":"","last_name":"Lieven","name_suffix":"","institution":"University of Manchester","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-02T02:00:00+08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27492/galley/17128/download/"}]}
