{"pk":28058,"title":"Adaptive planning in human search","subtitle":null,"abstract":"How do people plan ahead when searching for rewards? Weinvestigate planning in a foraging task in which participantssearch for rewards on an infinite two-dimensional grid. Ourresults show that their search is best-described by a modelwhich searches at least 3 steps ahead. Furthermore, partici-pants do not seem to update their beliefs during planning, butrather treat their initial beliefs as given, a strategy similar to aheuristic called root-sampling. This planning algorithm corre-sponds well with participants’ behavior in test problems withrestricted movement and varying degrees of information, out-performing more complex models. These results enrich ourunderstanding of adaptive planning in complex environments","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Planning; Decision Making; Tree Search; Forag-ing; Reinforcement Learning; Monte Carlo Sampling"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/36d1q0dz","frozenauthors":[{"first_name":"Moritz","middle_name":"J.F.","last_name":"Krusche","name_suffix":"","institution":"University of Warwick","department":""},{"first_name":"Eric","middle_name":"","last_name":"Schulz","name_suffix":"","institution":"Harvard","department":""},{"first_name":"Arthur","middle_name":"","last_name":"Guez","name_suffix":"","institution":"University of College London","department":""},{"first_name":"Maarten","middle_name":"","last_name":"Speekenbrink","name_suffix":"","institution":"University of College London","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/28058/galley/17697/download/"}]}
