We analyze data from a group problem-solving taskto gain insight into how people use information from past expe-riences and from others to achieve explore-exploit trade-offs incomplex environments. The behavior we observe is consistentwith the use of simple, reinforcement-based heuristics. Partic-ipants increase exploration immediately after experiencing alow payoff, and decrease exploration immediately after expe-riencing a high or improved payoff. We suggest that whetheran outcome is perceived as “high” or “low” is a dynamic func-tion of the outcome information available to participants. Thedegree to which the distribution of observed information re-flects the true range of possible outcomes plays an importantrole in determining whether or not this heuristic is adaptive ina given environment.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"exploration; exploitation; networks; social learn-ing"}],"section":"Papers with Poster Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9xm5w299","frozenauthors":[{"first_name":"Sabina","middle_name":"J.","last_name":"Sloman","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"Robert","middle_name":"L.","last_name":"Goldstone","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Cleotilde","middle_name":"","last_name":"Gonzalez","name_suffix":"","institution":"Carnegie Mellon University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28881/galley/18752/download/"}]}
