DESCRIPTION:Goal-directed movements rely on both egocentric (target relati
 ve to the observer) and allocentric (target relative to landmarks) spatial
  representations. So far\, it is widely unknown which factors determine th
 e use of allocentric information when we localize objects in space. To pro
 be allocentric coding\, we established an object shift paradigm and asked 
 participants to encode the location of multiple objects presented in natur
 alistic 2D scenes or 3D virtual environments. After a brief delay\, a test
  scene reappeared with one of the objects missing (= target) and the other
  objects (= landmarks) systematically shifted in one direction. After the 
 test scene vanished\, participants had to indicate the remembered location
  of the target. By quantifying the positional error of the target relative
  to the physical shift of the landmarks we determined the contribution of 
 allocentric target representations. In my talk\, I will present a series o
 f behavioral experiments in which we identified key factors influencing th
 e use of allocentric spatial coding\, such as spatial proximity\, task rel
 evance\, scene coherence\, and scene semantics. Overall\, our results show
  that low-level as well as high-level factors influence how humans represe
 nt objects in naturalistic environments.\nSpeakers:\nProf. Dr. Katja Fiehl
