{"pk":28319,"title":"Identifying the structure of hypotheses that guide search during development","subtitle":null,"abstract":"People use hypothesis-driven search to learn about novel concepts, favoring information sources that reduce uncertaintyacross a set of hypotheses about a target concept. We used childrens information search to investigate their reliance on twotypes of hypothesis spaces: exemplar-based representations or a hierarchical hypothesis space based on cue abstraction.Five- to seven-year-olds learned to rank monsters according to a hierarchical decision rule involving two cues (shape andcolor). Children generated evidence by selecting pairs of monsters and observing which one ranked higher; they werethen tested on whether they learned the decision rule and correct ranking. A comparison of exemplar-based and cue-based Bayesian models revealed that all children made search decisions predicted by the exemplar-based model, but olderchildren could use collected evidence to infer the underlying hierarchical structure. These results suggest a dissociationbetween the representations used to drive search and to make inferences from evidence during development.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Abstracts-Posters","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7zs6w9db","frozenauthors":[{"first_name":"Doug","middle_name":"","last_name":"Markant","name_suffix":"","institution":"University of North Carolina at Charlotte","department":""},{"first_name":"Angela","middle_name":"","last_name":"Jones","name_suffix":"","institution":"Max Planck Institute for Human Development","department":""},{"first_name":"Thorsten","middle_name":"","last_name":"Pachur","name_suffix":"","institution":"Max Planck Institute for Human Development","department":""},{"first_name":"Alison","middle_name":"","last_name":"Gopnik","name_suffix":"","institution":"University of California at Berkeley","department":""},{"first_name":"Azzurra","middle_name":"","last_name":"Ruggeri","name_suffix":"","institution":"Max Planck Institute for Human Development","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T10:00:00-08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28319/galley/18004/download/"}]}
