{"pk":26299,"title":"Semantic, Lexical, and Geographic Cues are used in Geographic Fluency","subtitle":null,"abstract":"Semantic fluency tasks have increasingly been used to probethe structure of human memory, adopting methodologies fromthe ecological foraging literature to describe memory as a tra-jectory through semantic space. Clusters of semantically re-lated items are often produced together, and the transitions be-tween these clusters of semantically related items are consis-tent with theories of optimal foraging, where the search pro-cess exhibits a balance between exploration and exploitationbehaviors (Hills, Jones, & Todd, 2012). Here, we use a seman-tic fluency memory task in which subjects recall geographiclocations. For each pairwise transition, we measure tempo-ral, geographic, semantic, lexical, and phonetic distances. Ingeneral, the dimensions are loosely but reliably correlated witheach other. Segmentation of the retrieval sequence into patchessupports the notion that subjects strategically leave patches aswithin-patch resources diminish, but also suggests that sub-jects may shift their attention between different sources of in-formation, perhaps reflecting dynamically changing patch def-initions.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Memory search; Semantic fluency; Optimal for-aging; Spatial search"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0cs2k9z0","frozenauthors":[{"first_name":"Janelle","middle_name":"","last_name":"Szary","name_suffix":"","institution":"Indiana University Bloomington","department":""},{"first_name":"Michael","middle_name":"N.","last_name":"Jones","name_suffix":"","institution":"Indiana University Bloomington","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26299/galley/15935/download/"}]}
