People rely on multiple frames of reference (FORs) to represent and update spatial relationships of different objects in a complex environment. According to the "Frame of Reference-based Map of Salience" theory (FORMS), FORs with high salience are processed in priority, and human performance is determined by the interaction of all relevant FOR-based representations. We conducted a modified two-cannon task manipulating conflicts among FORs (e.g., egocentric [FOR-EFOR], intrinsic [FOR-IFOR]) in order to explore how FORs interact with each other. We found that participants responded slower when two IFORs were incongruent than when they were congruent. There was also an interaction between these two conflicts. Moreover, the effect size of conflict between two IFORs was much larger than that between an IFOR and an EFOR. These results suggest that although the IFOR and EFOR may be coded by different spatial representations, they rely on a common processing mechanism and compete with each other. The findings from the current study provide support for the FORMS theory.
人们依靠多个参照系（FORs）来表征和更新复杂环境中不同物体的空间关系。根据“基于参照系的显著性地图”理论（FORMS），具有高显著性的参照系会被优先处理，而人类的表现则由所有相关的基于参照系的表征之间的相互作用决定。我们进行了一项经过修改的双炮任务，操纵参照系之间的冲突（例如，自我中心参照系[FOR-EFOR]、固有参照系[FOR-IFOR]），以探究参照系之间是如何相互作用的。我们发现，当两个固有参照系不一致时，参与者的反应比它们一致时更慢。这两种冲突之间也存在相互作用。此外，两个固有参照系之间冲突的效应大小远大于固有参照系与自我中心参照系之间冲突的效应大小。这些结果表明，尽管固有参照系和自我中心参照系可能由不同的空间表征进行编码，但它们依赖于一种共同的处理机制并相互竞争。当前研究的结果为FORMS理论提供了支持。
