{"pk":27657,"title":"Statistical Learning Contributions to Semantic Knowledge Development","subtitle":null,"abstract":"The organization of semantic knowledge according to relations between concepts influences many facets of highercognition. Therefore, understanding the origins of relations knowledge is a key focus of cognitive development research. Thisstudy investigated the contributions of environmental statistical regularities to relations knowledge in preschool-age children.Using CHILDES to estimate co-occurrence between familiar items, we constructed triads consisting of a target, related distrac-tor, and unrelated distractor in which targets and related distractors consistently co-occurred (e.g., sock-foot), belonged to thesame taxonomic category (e.g., sock-coat), or both (e.g., sock-shoe). Using a Visual World paradigm, we then measured rela-tions knowledge as the degree to which children looked at related versus unrelated distractors when asked to look for targets.The results revealed that co-occurrence, regardless of taxonomic relatedness, influenced whether participants looked signifi-cantly more at related versus unrelated distractors. These findings demonstrate that co-occurrence regularities between entitiesin the environment shape knowledge organization.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2sv3n814","frozenauthors":[{"first_name":"Layla","middle_name":"","last_name":"Unger","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"Anna","middle_name":"","last_name":"Fisher","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"Robert","middle_name":"","last_name":"Powers","name_suffix":"","institution":"Carnegie Mellon University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T21:00:00+03:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27657/galley/17293/download/"}]}
