{"pk":26856,"title":"Empirical tests of large-scale collaborative recall","subtitle":null,"abstract":"Much of our knowledge is transmitted socially rather thanthrough firsthand experience. Even our memories depend onrecollections of those around us. Surprisingly, when people re-call memories with others, they do not reach the potential num-ber of items they could have recalled alone. This phenomenonis called collaborative inhibition. Recently, Luhmann and Ra-jaram (2015) analyzed the dynamics of collaborative inhibitionat scale with an agent-based model, extrapolating from previ-ous small-scale laboratory experiments. We tested their modelagainst human data collected in a large-scale experiment andfound that participants demonstrate non-monotonicities not ev-ident in these predictions. We next analyzed memory transmis-sion beyond directly interacting agents by placing agents intonetworks. Contrary to model predictions, we observed highsimilarity only within directly interacting pairs. By comparingbehavior to model predictions in large-scale experiments, wereveal unexpected results that motivate future work in eluci-dating the algorithms underlying collaborative memory.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"collaborative memory; collaborative inhibition;network transmission; crowdsourcing; agent-based modeling"}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7440w48w","frozenauthors":[{"first_name":"Monica","middle_name":"A.","last_name":"Gates","name_suffix":"","institution":"University of California, Berkeley","department":""},{"first_name":"Jordan","middle_name":"W.","last_name":"Suchow","name_suffix":"","institution":"University of California, Berkeley","department":""},{"first_name":"Thomas","middle_name":"L.","last_name":"Griffiths","name_suffix":"","institution":"University of California, Berkeley","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/26856/galley/16492/download/"}]}
