{"pk":27909,"title":"Measuring Belief Bias with Ternary Response Sets","subtitle":null,"abstract":"Belief bias in syllogistic reasoning refers to the finding thatindividuals are more likely to accept believable than unbeliev-able conclusions independent of their logical validity. Mosttheories argue that belief bias is driven by differences in rea-soning processes between believable and unbelievable syllo-gisms. In contrast, Dube, Rotello, and Heit (2010) proposedthat belief bias is solely an effect of response processes. Weinvestigated belief bias without having to rely on response biasmanipulations (Klauer, Musch, and Naumer, 2000) or confi-dence ratings (Dube et al., 2010). Instead, we added a thirdresponse (“I don’t know”) to the usual binary response set(“Yes”/“No”). This allowed us to test belief bias with a fullyidentified multinomial processing tree model, in a hierarchicalBayesian framework. We found evidence that the belief biasis driven by differences in response processes. Evidence for adifference in reasoning processes was inconclusive.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"belief bias; syllogisms; multinomial processing tree models"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/895205x6","frozenauthors":[{"first_name":"Samuel","middle_name":"","last_name":"Winiger","name_suffix":"","institution":"University of Zurich","department":""},{"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":""}],"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/27909/galley/17547/download/"}]}
