{"pk":27251,"title":"When do learned transformations influence similarity and categorization?","subtitle":null,"abstract":"The transformational theory of similarity suggests that whenjudging similarity, people are sensitive to the number of trans-formation operations needed to make two compared repre-sentations match. Although this theory has been influential,little is known about how transformations are learned andto what extent learned transformations affect similarity judg-ments. This paper presents two experiments addressing thesequestions, in which people learned categories defined by atransformation. In Experiment 1, when the transformationswere directly visible, people had no trouble learning and ap-plied their knowledge to similarity and categorization judg-ments involving previously unseen items. In Experiment 2,the task required transformations to be inferred rather than ob-served. People were still able to learn the categories, but inthis more difficult case ratings were less strongly affected bytraining. Overall, this work suggests that newly learned trans-formations can impact similarity judgments but the salience ofthe transformation has a large impact on transfer.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"similarity; category learning; transformationalsimilarity"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5mn0t2r8","frozenauthors":[{"first_name":"Steven","middle_name":"","last_name":"Langsford","name_suffix":"","institution":"University of Adelaide","department":""},{"first_name":"Andrew","middle_name":"T.","last_name":"Hendrickson","name_suffix":"","institution":"Tilburg University","department":""},{"first_name":"Amy","middle_name":"","last_name":"Perfors","name_suffix":"","institution":"University of Adelaide","department":""},{"first_name":"Daniel","middle_name":"J.","last_name":"Navarro","name_suffix":"","institution":"University of New South Wales","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/27251/galley/16887/download/"}]}
