{"pk":27122,"title":"PACKER: An Exemplar Model of Category Generation","subtitle":null,"abstract":"Generating new concepts is an intriguing yet understudiedtopic in cognitive science. In this paper, we present a novelexemplar model of category generation: PACKER (ProducingAlike and Contrasting Knowledge using Exemplar Representa-tions). PACKER’s core design assumptions are (1) categoriesare represented as exemplars in a multidimensional psycholog-ical space, (2) generated items should be similar to exemplarsof the same category, and (3) generated categories should bedissimilar to existing categories. A behavioral study revealsstrong effects of contrast- and target-class similarity. Theseeffects are novel empirical phenomena, which are directly pre-dicted by the PACKER model but are not explained by existingformal approaches.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Categorization"},{"word":"exemplar models"},{"word":"category gener-ation"},{"word":"creative cognition"},{"word":"computational modeling."}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1k55q8c8","frozenauthors":[{"first_name":"Nolan","middle_name":"","last_name":"Conaway","name_suffix":"","institution":"University of Wisconsin - Madison","department":""},{"first_name":"Joseph","middle_name":"L.","last_name":"Austerweil","name_suffix":"","institution":"University of Wisconsin - Madison","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/27122/galley/16758/download/"}]}
