To test this, participants walked along a route in a virtual environment. They were asked to remember half of the intersections by what they saw. At the other 50% of intersections they heard an arbitrary name which they also had to remember. In the test phase they were teleported to different intersections and had to indicate the direction the route went on. At intersections without a name they performed faster and more accurately. In a second experiment meaningful names were used instead. Participants now performed better at named intersection. The results indicate an interaction between language and the presumably embodied wayfinding system. This interaction cannot be explained by a limited common resource, depth of processing, overshadowing, or linguistic scaffolding. However, it is consistent with dual coding. http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de Department Bülthoff http://cognitivesciencesociety.org/conference2009/index.html Biologische Kybernetik Max-Planck-Gesellschaft Amsterdam, Netherlands 31st Annual Conference of the Cognitive Science Society (CogSci 2009) en meilingerTMeilinger jspJSchulte-Pelkum frankensteinJFrankenstein naimaNLaharnar GHardieß hamHAMallot hhbHHBülthoff poster 5246 2008 10 9 32 This experiment tested whether vista spaces such as rooms or plazas are encoded differently in memory compared to environmental spaces such as buildings or cities. Participants learned an immersive virtual environment by walking through it in one direction. The environment consisted of seven corridors forming a labyrinth within which target objects were located. The participants either learned this environmental space alone, or distant mountains provided additional compass information. In a third condition, this labyrinth was located within a big hall (i.e., a vista space) which allowed self-localisation with respect to the vista space of the hall. In the testing phase, participants were teleported to different locations in the environment and were asked to identify their location and heading first, and then to point towards previously learned targets. In general, participants self localized faster when oriented in the direction in which they originally learned each corridor. However, a subset of participants showed a different orientation specificity in their pointing performance originating more from the orientation of the mountains or the hall. These participants were identified in catch trials after the experiment. The results are first hints for a difference in memory for vista and environmental spaces. http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de Department Bülthoff Biologische Kybernetik Max-Planck-Gesellschaft Dresden, Germany 9.

Participants learned an immersive virtual environment by walking in one direction. The environment consisted of seven corridors within which target objects were located. In the testing phase, participants were teleported to different locations in the environment and were asked to identify their location and heading and then to point towards previously learned targets. In experiment 1 eighteen participants could see the whole corridor and were able to turn their head during the testing phase, whereas in experiment 2 visibility was limited and the twenty participants were asked to not turn their heads during pointing. Reference direction theory assumes a global reference direction underlying the memory of the whole layout and would predict better performance when oriented in the global reference direction. However, no support was found for the reference direction theory. Instead, as predicted by view-dependent theories, participants pointed more accurately when oriented in the direction in which they originally learned each corridor, even when visibility was limited to one meter for all orientations (all results p<.05). When the whole corridor was visible, participants also self-localised faster when oriented in the learned direction. In direct comparison participants pointed more accurately when facing the learned direction instead of the global reference direction. With the corridors visible they also self-localised faster. No support was found for an exclusive orientation-independent memory as performance was orientation-dependent with respect to the learned orientation. We propose a ‘network of reference frames’ theory which extends the view-dependent theory by stating how locations learned from different views are connected within a spatial network. This theory is able to integrate elements of the different theoretical positions. http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de http://www.kyb.tuebingen.mpg.de Department Bülthoff http://www.twk.tuebingen.mpg.de/twk07/abstract.php?_load_id=meilinger01 Biologische Kybernetik Max-Planck-Gesellschaft Tübingen, Germany 10th Tübinger Wahrnehmungskonferenz (TWK 2007) en meilingerTMeilinger bernieBERiecke naimaNLaharnar hhbHHBülthoff
