| contents | Remembered landmarks enhance the precision of path integration John W. Philbeck Shannon O´Leary Psicología When navigating by path integration, knowledge of ones position becomesincreasingly uncertain as one walks from a known location. Thisuncertainty decreases if one perceives a known landmark location nearby.We hypothesized that remembering landmarks might serve a similar purposefor path integration as directly perceiving them. If this is true, walking neara remembered landmark location should enhance response consistency inpath integration tasks. To test this, we asked participants to view a targetand then attempt to walk to it without vision. Some participants saw thetarget plus a landmark during the preview. Compared with no-landmarktrials, response consistency nearly doubled when participants passed near theremembered landmark location. Similar results were obtained whenparticipants could audibly perceive the landmark while walking. A controlexperiment ruled out perceptual context effects during the preview. Weconclude that remembered landmarks can enhance path integration eventhough they are not directly perceived. 2005 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16926102 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.1 Vol.26 |
