一个有影响力的空间导航理论指出，环境的边界形状优先于其他空间线索进行编码，因此它不受其他信息源的干扰。我们探索了这一主张3 intradimensional-extradimensional移位实验，旨在研究在虚拟导航任务的地标和环境的几何特征的相互作用。在实验1和2中，参与者首先被要求找到一个隐藏的目标使用的信息所提供的形状的竞技场或地标集成到竞技场边界（实验1）或在竞技场本身（实验2）。然后，参与者被转移到一个不同形状的竞技场，其中包含新的地标，并再次要求找到一个隐藏的目标。在这两个实验中，根据来自先前相关的相同维度（维度内转移）的线索进行导航的参与者比根据来自先前不相关的维度（维度外转移）的线索进行导航的参与者更快地学会了找到目标。这表明形状信息在学习环境时并不具有特殊的地位。实验3复制实验2，并评估参与者的全球形状的导航舞台的认识。在整个实验中，当地标与导航相关时，识别会减弱。这些实验的结果进行了讨论的联想和非联想的空间学习理论。
An influential theory of spatial navigation states that the boundary shape of an environment is preferentially encoded over and above other spatial cues, such that it is impervious to interference from alternative sources of information. We explored this claim with 3 intradimensional–extradimensional shift experiments, designed to examine the interaction of landmark and geometric features of the environment in a virtual navigation task. In Experiments 1 and 2, participants were first required to find a hidden goal using information provided by the shape of the arena or landmarks integrated into the arena boundary (Experiment 1) or within the arena itself (Experiment 2). Participants were then transferred to a different-shaped arena that contained novel landmarks and were again required to find a hidden goal. In both experiments, participants who were navigating on the basis of cues that were from the same dimension that was previously relevant (intradimensional shift) learned to find the goal significantly faster than participants who were navigating on the basis of cues that were from a dimension that was previously irrelevant (extradimensional shift). This suggests that shape information does not hold special status when learning about an environment. Experiment 3 replicated Experiment 2 and also assessed participants’ recognition of the global shape of the navigated arenas. Recognition was attenuated when landmarks were relevant to navigation throughout the experiment. The results of these experiments are discussed in terms of associative and non-associative theories of spatial learning.
