{"pk":27191,"title":"Leveraging mutual exclusivity for faster cross-situational wordlearning: A theoretical analysis","subtitle":null,"abstract":"Past mechanistic accounts of children’s word learningclaim that a simple type of cross-situational learning ispowerful enough to match observed rates of learning,even in quite ambiguous situations. However, a limita-tion in some of these analyses is their reliance on an un-realistic assumption that the learner only hears a word insituations containing the intended referent. This studyanalyzed a more general type of cross-situational learn-ing based on the relative frequency of word-object pairs,and found it to be slower than the simple mechanismanalyzed in prior work. We then analytically exploredwhether relative-frequency learning can be improved byincorporating the mutual exclusivity (ME) principle–an assumption that words map to objects 1-to-1. Ouranalyses show that with a certain type of correlation inword-to-word relationship, ME makes relative frequencylearning as efficient as fast-mapping, which can learn aword in one exposure.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Word learning; Cross-situational learningmodels; Mutual exclusivity; Language acquisition"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6qh0070q","frozenauthors":[{"first_name":"Shohei","middle_name":"","last_name":"Hidaka","name_suffix":"","institution":"Japan Advanced Institute of Science and Technology","department":""},{"first_name":"Takuma","middle_name":"","last_name":"Torii","name_suffix":"","institution":"Japan Advanced Institute of Science and Technology","department":""},{"first_name":"George","middle_name":"","last_name":"Kachergis","name_suffix":"","institution":"Radboud University","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/27191/galley/16827/download/"}]}
