Reg-ularities and differences in the age of acquisition for wordsacross languages yield insights regarding the mechanismsguiding word learning. In a large-scale corpus analysis,we estimate the ages at which 9,200 children learn 300-400words in seven languages, predicting them on the basis ofindependently-derived linguistic, environmental, and concep-tual factors. Predictors were surprisingly consistent across lan-guages, but varied across development and as a function oflexical category (e.g., concreteness predicted nouns while lin-guistic structure predicted function words). By leveraging dataat a significantly larger scale than previous work, our analyseshighlight the power that emerges from unifying previously dis-parate theories, but also reveal the amount of reliable variationthat still remains unexplained.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"language acquisition; word learning; development"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9sn4p5f9","frozenauthors":[{"first_name":"Mika","middle_name":"","last_name":"Braginsky","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Daniel","middle_name":"","last_name":"Yurovsky","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Virginia","middle_name":"A.","last_name":"Marchman","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Michael","middle_name":"C.","last_name":"Frank","name_suffix":"","institution":"Stanford University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26348/galley/15984/download/"}]}
