As people move through an environment, they typically change both their heading and their location relative to the surrounds. During such changes, people update their changing orientations with respect to surrounding objects. People can also update after only imagining such typical movements, but not as quickly or accurately as after actual movement. In the present study, blindfolded subjects pointed to objects after real and imagined walks. The role of rotational and translational components of movement were contrasted. The difficulty of imagined updating was found to be due to imagined rotation and not to imagined translation; updating after the latter was just as quick and accurate as updating after actual rotations and translations. Implications for understanding primary spatial orientation, the organization of spatial knowledge, and spatial-imagination processes are discussed.
当人们在环境中移动时，他们通常会改变自己的前进方向以及相对于周围环境的位置。在这种变化过程中，人们会根据周围物体更新自己不断变化的方向。人们在仅仅想象了这种典型运动之后也能够进行更新，但不如实际运动之后那样迅速和准确。在本研究中，蒙住眼睛的受试者在实际行走和想象行走之后指向物体。对运动的旋转和平移成分的作用进行了对比。研究发现，想象更新的困难是由于想象中的旋转，而不是想象中的平移；想象平移之后的更新与实际旋转和平移之后的更新一样迅速和准确。文中讨论了这一发现对于理解基本空间定向、空间知识的组织以及空间想象过程的意义。
