{"pk":28841,"title":"Family Resemblance in Unsupervised Categorization: A Dissociation Between\nProduction and Evaluation","subtitle":null,"abstract":"A plurality of the categories we hold exhibit family\nresemblance (FR; i.e., many characteristic but few defining\nfeatures), suggesting FR may occupy a central role in human\ncategory formation. However, research in unsupervised\nlearning has shown that when people are asked to sort an\narray of novel items into categories, they ubiquitously use a\nunidimensional (UNI) rule – despite the availability of a FR\nsolution. This work suggests that, perhaps, FR similarity is\nnot a core tendency in category formation. Here, we question\nwhether the UNI bias is a result of the sorting paradigm.\nSpecifically, we speculate the paradigm conflates two\ncomponents vital for category formation: production and\nevaluation. Across three experiments we show that when\nevaluation is separated from generation – by using a novel\nforced-choice task that pits different category organizational\nschemes against one another – people exhibit a FR over UNI\npreference. The implications of these results are discussed.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"unsupervised categorization; similarity; family\nresemblance; unidimensional bias; category construction"}],"section":"Papers with Poster Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4909d75j","frozenauthors":[{"first_name":"John","middle_name":"D.","last_name":"Patterson","name_suffix":"","institution":"Binghamton University","department":""},{"first_name":"Sean","middle_name":"","last_name":"Snoddy","name_suffix":"","institution":"Binghamton University","department":""},{"first_name":"Kenneth","middle_name":"J.","last_name":"Kurtz","name_suffix":"","institution":"Binghamton University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28841/galley/18712/download/"}]}
