{"pk":30105,"title":"Influences of both prior knowledge and recent historyon visual working memory","subtitle":null,"abstract":"Existing knowledge shapes and distorts our memories, serv-ing as a prior for newly encoded information. Here, we in-vestigate the role of stable long-term priors (e.g. categoricalknowledge) in conjunction with priors arising from recentlyencountered information (e.g. ’serial dependence’) in visualworking memory for color. We use an iterated reproductionparadigm to allow a model-free assessment of the role of suchpriors. In Experiment 1, we find that participants’ reports re-liably converge to certain areas of color space, but that thisconvergence is largely distinct for different individuals, sug-gesting responses are biased by more than just shared categoryknowledge. In Experiment 2, we explicitly manipulate trialn-1 and find recent history plays a major role in participants’reports. Thus, we find that both global prior knowledge and re-cent trial information have biasing influences on visual work-ing memory, demonstrating an important role for both short-and long-term priors in actively maintained information.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"working memory"},{"word":"serial dependence"},{"word":"prior knowl-edge"},{"word":"iterated learning"},{"word":"reconstructive memory"}],"section":"Poster Session 3","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3wk1b0qn","frozenauthors":[{"first_name":"Isabella","middle_name":"","last_name":"DeStefano","name_suffix":"","institution":"University of California, San Diego","department":""},{"first_name":"Edward","middle_name":"","last_name":"Vul","name_suffix":"","institution":"University of California, San Diego","department":""},{"first_name":"Timothy","middle_name":"F.","last_name":"Brady","name_suffix":"","institution":"University of California, San Diego","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30105/galley/19959/download/"}]}
