In 3 experiments, the authors examined how misalignment of egocentric and exocentric reference frames affects cardinal direction judgments. Experiments 1 and 2 demonstrated large differences in the accuracy and speed with which 104 less experienced and 7 experienced navigators made cardinal direction judgments. Reference-frame misalignment was associated with large performance decrements. The extent of these decrements diminished as ability and experience increased: however, even experienced navigators showed decrements when reference frames were misaligned. In Experiment 3, the authors used 55 college students to examine the individual subtasks of a common strategy for cardinal direction judgments and to isolate the effects of reference-frame misalignment to a particular subtask of this strategy. The tasks and strategies studied in this article can be applied in the development of navigational training and interfaces.
在3项实验中，作者研究了以自我为中心和以外界为中心的参照系的不一致如何影响基本方向判断。实验1和实验2表明，104名经验较少的导航员和7名经验丰富的导航员在进行基本方向判断时，在准确性和速度上存在巨大差异。参照系的不一致与表现大幅下降有关。随着能力和经验的增加，这些下降的程度有所减小：然而，即使是经验丰富的导航员，当参照系不一致时也会出现表现下降。在实验3中，作者使用55名大学生来研究基本方向判断的一种常见策略的各个子任务，并将参照系不一致的影响分离到该策略的一个特定子任务上。本文研究的任务和策略可应用于导航训练和界面的开发。
