Abstract: | The present study investigated the role of object-centered reference systems in memories of objects' locations. Participants
committed to memory the locations and orientations of either 11 human avatars (Experiment 1) or 11 animal models (Experiment 2) displayed in a desktop virtual environment and then completed judgments of relative directions, in which they pointed to
objects from imagined vantage points corresponding to the locations of the objects. Results showed that, with avatars, performance
was better when the imagined heading was congruent with the facing direction of the avatar located at the imagined vantage
point. With animal models, no such facilitation was found. For both types of stimuli, performance was better for the learning
view than for the novel 135° view. Results demonstrate that memories of the locations of objects are affected by object-centered
reference systems and are consistent with conjectures that spatial memories are hierarchies of spatial reference systems,
with higher levels corresponding to larger scales of space. |
