{"pk":29891,"title":"Childrens use of linguistic and non-linguistic negation in reasoning by thedisjunctive syllogism","subtitle":null,"abstract":"Whether logical inference is available without language is highly debated. One such inference is the disjunctive syllogism(A Or B, Not A, Therefore B). Evidence from a search task that required disjunctive reasoning suggests that that thesyllogism is unavailable before age 3 (Mody & Carey, 2016). However, in a replication of the same task using language(i.e., verbal negation), even 2.5-year-olds succeeded (Grigoroglou, et al., 2019). Here we explore the role of languagein childrens logical reasoning. 2.5- to 4-year-olds performed the non-linguistic task, after a short training in reasoningby exclusion. Half of the children received linguistic training (e.g., heard there is no coin in X cup); half received non-linguistic training (i.e., saw that one location was empty). Results show that 2.5- and 3-year-olds were more successful inreasoning with the disjunctive syllogism after the linguistic training. Thus, offering children the premise Not A verballyfacilitated logical reasoning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Session 2","is_remote":true,"remote_url":"https://escholarship.org/uc/item/55z1x26g","frozenauthors":[{"first_name":"Myrto","middle_name":"","last_name":"Grigoroglou","name_suffix":"","institution":"University of Toronto","department":""},{"first_name":"Patricia","middle_name":"","last_name":"Ganea","name_suffix":"","institution":"University of Toronto","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29891/galley/19745/download/"}]}
