A substantial amount of research has demonstrated the importance of reference frames in organizing memory of object locations in both small and large environments. However, to date, little research has examined how the object locations represented in one reference frame are specified relative to object locations represented in another. In a series of 4 experiments, we demonstrate that multiple microreference frames can be established in memory for sets of objects that are spatially and semantically distinct, and that the spatial relations between these microreference frames are specified in memory by means of a more global, macroreference frame. Additionally, these experiments demonstrate that an established macroreference frame can influence which of several microreference frames will be coded in memory, but that a previously established microreference frame had no appreciable influence on the subsequent formation of a macroreference frame. These results are interpreted as indicating that the same cognitive mechanisms underlie interobject coding across multiple environmental scales. The implications for reference frame theories and theories positing hierarchical memory organization are discussed.
大量研究表明，参考系在组织小环境和大环境中的物体位置记忆方面具有重要意义。然而，迄今为止，很少有研究探讨在一个参考系中表示的物体位置相对于在另一个参考系中表示的物体位置是如何被指定的。在一系列 4 项实验中，我们证明了可以在记忆中为空间和语义上不同的物体集建立多个微参考系，并且这些微参考系之间的空间关系可以通过更全局的宏参考系在记忆中指定。此外，这些实验表明，已建立的宏参考系可以影响将在记忆中编码的几个微参考系中的哪一个，但先前建立的微参考系对随后形成的宏参考系没有明显影响。这些结果表明，多个环境尺度上的物体间编码是由相同的认知机制来支撑的。讨论了这些结果对参考系理论和假设分层记忆组织的理论的意义。
