四项实验测试了记忆中物体位置是否存在持久的空间表征。先前的研究表明，在某些条件下，使用记忆指向对象的内部一致性会因迷失方向而被破坏。这种迷失方向效应归因于物体位置的缺乏或不精确的持久空间表示。实验 1 复制了标准的定向障碍效应。参与者学习了不规则布局中物体的位置，然后在身体转向面对物体并迷失方向后指向物体。观察到预期的迷失方向。在实验2中，在迷失方向后，参与者被要求想象他们面对原来的学习方向，然后身体转向采用测试方向。在实验3中，参与者迷失方向后转向采用测试方向，然后由实验者告知原来的观看方向。在实验2或3中没有观察到迷失方向的效果。在实验4中，迷失方向后，参与者转向面对测试方向，但没有被告知原来的学习方向。与实验1一样，观察到定向障碍效应。这些结果表明，根据与学习视图平行的空间参考方向指定的对象位置存在持久的空间表示，并且迷失方向效应是由迷失方向后恢复相对于测试方向的空间参考方向的不确定性引起的。
Four experiments tested whether there are enduring spatial representations of objects’ locations in memory. Previous studies have shown that under certain conditions the internal consistency of pointing to objects using memory is disrupted by disorientation. This disorientation effect has been attributed to an absence of or to imprecise enduring spatial representations of objects’ locations. Experiment 1 replicated the standard disorientation effect. Participants learned locations of objects in an irregular layout and then pointed to objects after physically turning to face an object and after disorientation. The expected disorientation was observed. In Experiment 2, after disorientation, participants were asked to imagine they were facing the original learning direction and then physically turned to adopt the test orientation. In Experiment 3, after disorientation, participants turned to adopt the test orientation and then were informed of the original viewing direction by the experimenter. A disorientation effect was not observed in Experiment 2 or 3. In Experiment 4, after disorientation, participants turned to face the test orientation but were not told the original learning orientation. As in Experiment 1, a disorientation effect was observed. These results suggest that there are enduring spatial representations of objects’ locations specified in terms of a spatial reference direction parallel to the learning view, and that the disorientation effect is caused by uncertainty in recovering the spatial reference direction relative to the testing orientation following disorientation.
