{"pk":30147,"title":"The effect of context on decisions:Decision by sampling based on probabilistic beliefs","subtitle":null,"abstract":"Previous studies have shown that people’s decisions are af-fected by context in various ways, even when they are providedwith the same or analogous information. In the present study,we analyzed decisions based on verbally expressed probabilis-tic phrases (verbal probabilities) and examined how contextualfactors affected such decisions. In particular, we focused on thedifference in contexts that produced different probabilistic be-liefs with regards to uncertain events. We hypothesized thatsuch contextual effects could be explained in terms of a Deci-sion by Sampling (DbS) account (Stewart et al., 2006). In orderto examine our hypothesis, we proposed a modified version ofDbS, Decision by Belief Sampling (DbBS), and conducted be-havioral experiment about decision making. In this experiment,we set different contexts that we expected to produce differentprobabilistic beliefs regarding uncertain events for decision-makers and examined how such differences affected decisionmaking. Results showed that decisions were significantly af-fected by the variation in contexts, and DbBS well explainedsuch effects.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"verbal probabilities; Decision by Sampling (DbS);directionality of verbal probabilities; contextual effects in de-cision making"}],"section":"Papers accepted as Posters, appearing in proceedings only","is_remote":true,"remote_url":"https://escholarship.org/uc/item/8bg0q0f8","frozenauthors":[{"first_name":"Hidehito","middle_name":"","last_name":"Honda","name_suffix":"","institution":"Otemon Gakuin University","department":""},{"first_name":"Toshihiko","middle_name":"","last_name":"Matsuka","name_suffix":"","institution":"Chiba University","department":""},{"first_name":"Kazuhiro","middle_name":"","last_name":"Ueda","name_suffix":"","institution":"The University of Tokyo","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30147/galley/20001/download/"}]}
