{"pk":27484,"title":"A picture falls under many categories: How ancient mathematical marks becameextinct","subtitle":null,"abstract":"The development of mathematical marking conventions from prehistory to the present is characterized by a trendfrom conventions with more iconic relationships to concrete structures of the physical world (such as more pictorial ancient landsurveying marks) to marking systems with less-iconic relationships to physical structures (that represent numbers, operations,infinity, and other more abstract concepts). We propose how certain constraints of perception-cognition induced conventionsthat made more-iconic (pictorial) marks controversial. These became too conceptually ambiguous to convey more abstractconceptual categories during the formalization of mathematics: Iconic properties of ancient proto-mathematical conventionsrecruited lower level perceptual capabilities developed to perceive-act in a concrete world of occluded surfaces-edges andwere suitable for conveying concrete structures (such as landforms during surveying). However, these were too conceptuallyambiguous to convey more abstract conceptual categories that emerged when mathematics was formalized because a (pictured)concrete structure can fall under many possible conceptual categories","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1627v4k9","frozenauthors":[{"first_name":"Peter","middle_name":"","last_name":"Coppin","name_suffix":"","institution":"University of Toronto","department":""},{"first_name":"Daemon","middle_name":"","last_name":"Retren","name_suffix":"","institution":"OCAD University","department":""},{"first_name":"Ambrose","middle_name":"","last_name":"Li","name_suffix":"","institution":"OCAD 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/27484/galley/17120/download/"}]}
