The Integration of Spatial Information across Different Perspectives
Year: 2008
Type: article
Abstract: The integration of spatial information across different\nperspectives or viewpoints is a frequent spatial task, yet\nrelatively little is known about it. In the present study,\nparticipants were shown three target locations from one point\nof view. After walking away, they either returned to the same\nlocation or to a novel location before being presented with\nthree additional target locations. Their task was to plan and\nnavigate the shortest possible path to visit all six target\nlocations. To successfully solve the task, participants had to\nintegrate different pieces of spatial information acquired from\ntwo viewpoints. We measured errors and the time to reach the\nfirst target. An increased number of errors in the condition\nincluding a perspective shift strongly suggest that participants\nencoded different views which had to be aligned in order to\nbe integrated. The fact that the increase in errors primarily\noriginated from the target locations presented first, indicates\nthat the first view was transformed into the perspective of the\nsecond view. Neither egocentric updating, allocentric\norientation-independent memory, nor allocentric reference\naxis theory can explain these results.
