{"pk":32838,"title":"Effects of Background Knowledge on Family Resemblance Sorting and Missing Features","subtitle":null,"abstract":"Despite people's strong bias to sort exemplars based on a single dimension, various situations where family resemblance (FR) categories tend to be created have been identified. In a previous study (Ahn 1990b), knowing prototypes or theories underlying categories led subjects to create FR categories. The current study investigates why existence of background knowledge encourages creation of F R categories. Comparison of results from two experiments indicates that there is no intrinsic tie between knowing theories or prototypes and F R structure. The role of background knowledge on FR sorting seems to lie in leading subjects to weight dimensions equally, in helping them to infer unavailable values in favor or F R sorting, and / or in relating surface dimensions in terms of a deeper feature.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations -- Regularities and Estimation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/1f90b86x","frozenauthors":[{"first_name":"Woo-kyoung","middle_name":"","last_name":"Ahn","name_suffix":"","institution":"University of Michigan","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1991-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/32838/galley/23898/download/"}]}
