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.
