Establishing and updating spatial relationships between objects in the environment is vital to maintaining situation awareness and supporting many socio-spatial tasks. In a complex environment, people often need to utilize multiple reference systems that are intrinsic to different objects (intrinsic frame of reference, IFOR), but these IFORs may conflict with each other in one or more ways. Current spatial cognition theories do not adequately address how people handle multi-IFOR reasoning problems. Two experiments manipulated relative orientations of two task-relevant objects with intrinsic axes of orientation as well as their relative task salience. Response times (RTs) decreased with increasing salience of the targeted IFOR. In addition, RTs increased as a consequence of intrinsic orientation conflict, but not by amount of orientation difference. The results suggest that people encounter difficulties when they have to process two conflicting IFOR representations, and that they seem to prioritize processing of each IFOR by salience.
建立和更新环境中物体之间的空间关系对于保持态势感知和支持许多社会空间任务至关重要。在复杂环境中，人们常常需要利用不同物体固有的多个参照系（固有参照系，IFOR），但这些IFOR可能在一个或多个方面相互冲突。当前的空间认知理论未能充分说明人们如何处理多IFOR推理问题。两项实验操纵了两个与任务相关物体的相对方向以及它们的固有方向轴及其相对任务显著性。反应时间（RT）随着目标IFOR显著性的增加而减少。此外，RT因固有方向冲突而增加，但不是因方向差异量而增加。结果表明，当人们必须处理两个相互冲突的IFOR表征时会遇到困难，而且他们似乎会根据显著性对每个IFOR的处理进行优先级排序。
