{"pk":27891,"title":"Using Ensembles of Cognitive Models to Answer Substantive Questions","subtitle":null,"abstract":"Cognitive measurement models decompose observed behav-ior into latent cognitive processes. For situations with morethan one condition, such models allow to test hypotheses onthe level of the latent processes. We propose a fully Bayesianensemble model approach to test hypotheses on the level ofthe latent processes in situations in which multiple measure-ment models or model classes exist. In the first step, one needsto perform a Bayesian model selection step comparing the hy-potheses within each model class. Aggregating the results ofthe first step yields ensemble posterior model probabilities. Weprovide an example for a working memory data set using anensemble of a resource model and a slots model.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"ensemble models"},{"word":"model selection"},{"word":"Bayesian inference"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4h2911rf","frozenauthors":[{"first_name":"Henrik","middle_name":"","last_name":"Singmann","name_suffix":"","institution":"University of Zurich","department":""},{"first_name":"David","middle_name":"","last_name":"Kellen","name_suffix":"","institution":"Syracuse","department":""},{"first_name":"Eda","middle_name":"","last_name":"Mizrak","name_suffix":"","institution":"UC Davis","department":""},{"first_name":"Ilke","middle_name":"","last_name":"Oztekin","name_suffix":"","institution":"NYU","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27891/galley/17529/download/"}]}
