Mou和McNamara（2002）最近提出了非自我中心参考框架（即，基于对象配置的空间结构的内在参考帧）被用于组织存储器中的空间关系。该理论并没有提出关于刺激阵列的内在结构是否是这种非自我中心编码的必要或充分条件的主张。我们表明，显着的内在轴在布局的对象既不必要，也不足以让人们使用非自我中心的参考框架在组织空间记忆。在实验1中，参与者被成功地指示采用非自我中心的首选方向的内存中的一系列对象没有显着的内在参考轴。在实验2中，没有任何指示，参与者采用了一个自我中心的首选方向与一个显着的内在轴阵列。这些结果表明，物理显着的阵列结构发挥了最小的影响编码的空间记忆通过非自我中心的参考框架。
Mou and McNamara (2002) have recently theorized that nonegocentric reference frames (viz., intrinsic reference frames, based on the spatial structure of a configuration of objects) are used to organize spatial relationships in memory. The theory has not made claims about whether the intrinsic structure of a stimulus array is necessary or sufficient for such nonegocentric coding. We demonstrate that salient intrinsic axes in a layout of objects are neither necessary nor sufficient for people to use a nonegocentric reference frame in organizing spatial memory. In Experiment 1, participants were successfully instructed to adopt a nonegocentric preferred direction in memory for an array of objects with no salient intrinsic reference axes. In Experiment 2, with no instructions, participants adopted an egocentric preferred direction for an array with a salient intrinsic axis. These results suggest that physically salient array structure exerts a minimal influence in the coding of spatial memory through nonegocentric reference frames.
