Zusammenfassung
While people frequently change perspectives around the ground plane, they less do so around the vertical plane. We investigated whether this difference in interacting with the environment affects spatial memories for different planes. In Experiment 1, participants memorized locations of colored tags on either a horizontal or a vertical board in a virtual room, and then relocated them to their original location from different perspectives (via rotating the board). Surprisingly, relocation was quicker and more accurate for the vertical than for the horizontal plane when spatial memory was accessed from the learning perspective or novel perspectives orthogonal to it. Therefore, spatial memory represented along vertical upright orientation can be better than that encoded with a front orientation. In Experiment 2, we rotated both the board and the whole virtual room to simulate the perspective change caused by observer’s movement. Performance decreased with increasing disparity between learning and test perspectives for the vertical plane but less so for the horizontal plane. Moreover, performance was clearly better when the room rotated with the board than not, suggesting that spatial locations were also represented with environmental frames of reference. These results demonstrate that spatial memories for horizontal and vertical planes are qualitatively different.
