{"pk":27427,"title":"Exploitative and Exploratory Attention in a Four-Armed Bandit Task","subtitle":null,"abstract":"When making decisions, we are often forced to choose\nbetween something safe we have chosen before, and\nsomething unknown to us that is inherently risky, but may\nprovide a better long-term outcome. This problem is known as\nthe Exploitation-Exploration (EE) Trade-Off. Most previous\nstudies on the EE Trade-Off have relied on response data,\nleading to some ambiguity over whether uncertainty leads to\ntrue exploratory behavior, or whether the pattern of\nresponding simply reflects a simpler ratio choice rule (such as\nthe Generalized Matching Law (Baum, 1974; Herrnstein,\n1961)). Here, we argue that the study of this issue can be\nenriched by measuring changes in attention (via eye-gaze),\nwith the potential to disambiguate these two accounts. We\nfind that when moving from certainty into uncertainty, the\noverall level of attention to stimuli in the task increases; a\nfinding we argue is outside of the scope of ratio choice rules.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Reinforcement Learning; Attention; Decision-\nMaking; Exploitation/Exploration Trade-Off; Bandit Task."}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/8ft623fx","frozenauthors":[{"first_name":"Adrian","middle_name":"R.","last_name":"Walker","name_suffix":"","institution":"UNSW Sydney","department":""},{"first_name":"Mike","middle_name":"E.","last_name":"Le Pelley","name_suffix":"","institution":"UNSW Sydney","department":""},{"first_name":"Tom","middle_name":"","last_name":"Beesley","name_suffix":"","institution":"UNSW Sydney","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27427/galley/17063/download/"}]}
