{ "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/" } ] }
