{"pk":27769,"title":"Do Humans Navigate via Random Walks? Modeling Navigation in a Semantic Word Game","subtitle":null,"abstract":"We investigate a method for formulating context- and task-\nspecific computational models of human performance in a con-\nstrained semantic memory task. In particular, we assume that\nmemory retrieval can only use a simple process – a random\nwalk – and examine whether the effect of context and task\nspecifications can be captured via a straightforward network\nestimation method that is sensitive to context and task. We find\nthat a random walk model on the context-specific networks\nmimics aggregate human performance.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"network analysis"},{"word":"Semantic search"},{"word":"spreading activation"},{"word":"Semantic memory"},{"word":"Random walks"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0bd1b52n","frozenauthors":[{"first_name":"Mohammad","middle_name":"Isyroqi","last_name":"Fatham","name_suffix":"","institution":"University of Kansas","department":""},{"first_name":"Eli","middle_name":"J","last_name":"Renfro","name_suffix":"","institution":"University of Kansas","department":""},{"first_name":"Joseph","middle_name":"L","last_name":"Austerweil","name_suffix":"","institution":"University of Wisonsin - Madison","department":""},{"first_name":"Nicole","middle_name":"M","last_name":"Beckage","name_suffix":"","institution":"University of Kansas; University of Wisconsin-Madison","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27769/galley/17409/download/"}]}
