{"pk":24090,"title":"Uncertainty affects planning effort, but not plans","subtitle":null,"abstract":"When people plan, they often do so in the face of uncertainty. However, little is known about how uncertainty affects planning. To study these effects, we used a reward gathering task in which the we varied the reliability of announced rewards varied from certain to completely random. We quantitatively compared several planning models. We found that participants used a suboptimal approach, failing to directly incorporate stochasticity into their planning. Instead, they \"compensated\" for uncertainty by decreasing their planning effort as stochasticity increased. First-move response time correspondingly decreased with increasing stochasticity. Our findings generalized to a manipulation of transition uncertainty. Together, these findings open the door to a more comprehensive and computationally grounded understanding of the role of stochasticity in planning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Cognitive Neuroscience; Psychology; Decision making; Reasoning; Computational Modeling"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0m9178tg","frozenauthors":[{"first_name":"Jordan","middle_name":"","last_name":"Lei","name_suffix":"","institution":"New York University","department":""},{"first_name":"Wei Ji","middle_name":"","last_name":"Ma","name_suffix":"","institution":"New York University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2024-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/24090/galley/13684/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/24090/galley/21688/download/"}]}
