{"pk":31736,"title":"Schema-based Categorization","subtitle":null,"abstract":"Many theories of conceptual organization assume the\nexistence of some form of mental similarity metric\n(Medin and Schaffer, 1978; Hintzman and Ludlum,\n1980; Nosofsky, 1988; Shepard, 1987; Kruschke, 1992, among others.) In the domain of categorization, such\ntheories have been called \"similarity-based\" (Murphy\nand Medin, 1985). Criticism of similarity-based the-\nstories has led to a call for \"theory-based\" models of\ncategorization (Murphy and Medin, 1985; Rips, 1989;\nBarsalou, 1991; Medin, 1989). Theory-based views\nremain somewhat vague, however. In this paper I\noutline a schema-based theory of conceptual organi-\nzation. T h e model depends on the notion of amen -\ntal similarity metric but makes use of connectionist\nlearning principles to develop a conceptual organiza-\ntion that solves a problem faced by purely similarity-\nbased models of categorization. I discuss the rela-\ntionship of this theory to similarity-based and theory- based accounts.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/09w6w1j7","frozenauthors":[{"first_name":"Benjamin","middle_name":"","last_name":"Martin","name_suffix":"","institution":"Stanford University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1993-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31736/galley/22804/download/"}]}
