Four experiments investigated the roles of layout geometry in the selection of intrinsic frames of reference in spatial memory. Participants learned the locations of objects in a room from 2 or 3 viewing perspectives. One view corresponded to the axis of bilateral symmetry of the layout, and the other view(s) was (were) nonorthogonal to the axis of bilateral symmetry. Judgments of relative direction using spatial memory were quicker for imagined headings parallel to the symmetric axis than for those parallel to the other viewing perspectives. This advantage disappeared when the symmetric axis was eliminated. Moreover, there was more consistency across participants in the selection of intrinsic axes when the layout contained an axis of bilateral symmetry than when it did not. These results indicate that the layout geometry affects the selection of intrinsic frames of reference supporting the intrinsic model of spatial memory proposed by W. Mou and T. P. McNamara (2002) and by A. L. Shelton and T. P. McNamara (2001).
四项实验研究了布局几何结构在空间记忆中内在参照系选择方面的作用。参与者从2个或3个观察视角学习房间内物体的位置。其中一个视角对应布局的双侧对称轴，而其他视角与双侧对称轴不垂直。当想象的方向平行于对称轴时，利用空间记忆进行的相对方向判断比平行于其他观察视角时更快。当对称轴被消除时，这种优势就消失了。此外，与没有双侧对称轴的布局相比，当布局包含双侧对称轴时，参与者在内在轴的选择上更具一致性。这些结果表明，布局几何结构会影响内在参照系的选择，这支持了W. Mou和T. P. McNamara（2002年）以及A. L. Shelton和T. P. McNamara（2001年）提出的空间记忆内在模型。
