A single view of a room-sized path produces an orientation-specific memory representation, yet when memory is tested at a location on the path, orientation-free performance is observed. Either a virtual-views or an updating hypothesis can account for orientation-free performance by attributing it, respectively, to an orientation-free long-term-memory representation or to a working-memory representation of the body's updated location relative to the path. Experiments 1 and 2 test these hypotheses by manipulating the test-site location and the complexity of the trajectory from the study site to the test site. Experiment 3 tests orientation to the test space as a function of trajectory complexity. Results support a virtual-views explanation for the orientation-free performance of males and an updating explanation for females.
对房间大小的路径的单一视角会产生特定方向的记忆表征，然而当在路径上的某个位置进行记忆测试时，会观察到无方向依赖的表现。虚拟视角或更新假说都可以解释无方向依赖的表现，分别将其归因于无方向依赖的长期记忆表征或身体相对于路径更新位置的工作记忆表征。实验1和实验2通过操纵测试地点的位置以及从学习地点到测试地点的轨迹复杂性来检验这些假说。实验3测试对测试空间的方向作为轨迹复杂性的函数。结果支持对男性无方向依赖表现的虚拟视角解释以及对女性的更新解释。
