{"pk":27030,"title":"A Computational Model for Constructing Preferences for Multiple Choice Options","subtitle":null,"abstract":"When choosing between multiple alternatives, people usuallydo not have ready-made preferences in their mind but ratherconstruct them on the go. The 2N-ary Choice Tree Model(Wollschlaeger & Diederich, 2012) proposes a preference con-struction process for N choice options from description, whichis based on attribute weights, differences between attribute val-ues, and noise. It is able to produce similarity, attraction,and compromise effects, which have become a benchmark formulti-alternative choice models, but also several other contextand reference point effects. Here, we present a new and math-ematically tractable version of the model – the Simple ChoiceTree Model – which also explains the above mentioned effectsand additionally accounts for the positive correlation betweenthe attraction and compromise effect, and the negative correla-tion between these two and the similarity effect as observed byBerkowitsch, Scheibehenne, and Rieskamp (2014).","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"computational model; multi-alternative choice;choice from description; preference construction; context ef-fects"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/8sr4k4m9","frozenauthors":[{"first_name":"Lena","middle_name":"M.","last_name":"Wollschlaeger","name_suffix":"","institution":"Jacobs University Bremen","department":""},{"first_name":"Adele","middle_name":"","last_name":"Diederich","name_suffix":"","institution":"Jacobs University Bremen","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-02T02:00:00+08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27030/galley/16666/download/"}]}
