两项研究调查了在真实的、想象的和模拟的运动过程中自我位置和方向的更新。受试者被暴露在一个两段的路径与段之间的转弯;他们的反应是转身面对原点，因为他们会，如果他们走的路径，并在第二段的结束。路径暴露的条件包括物理行走、根据口头描述想象行走、观看另一个人行走以及体验模拟行走的光流，在路径段之间有或没有物理转弯。IS受试者航行以更新航向的内部表示，但确实对路径轨迹进行了编码，他们应该根据路径段之间的转弯幅度进行翻转。这种系统性的翻转是描述和观看条件中的源，但不是物理行走。模拟光流本身不足以诱导空间更新，支持正确的转向反应。
Two studies investigated updating of self-position and heading during real, imagined, and simulated locomotion. Subjects were exposed to a two-segment path with a turn between segments; they responded by turning to face the origin as they would if they had walked the path and were at the end of the second segment. The conditions of pathway exposure included physical walking, imagined walking SI om a verbal description, watching another person walk, and experiencing optic flow that simulated walking, with or without a physical turn between the path segments. IS subjects Sailed to update an internal representation of heading, bur did encode the pathway trajectory, they should have overturned hy the magnitude of the turn between the path segments. Such systematic overturning was Source in the description and watching conditions, but not with physical walking. Simulated optic flow was not by itself sufficient to induce spatial updating that supported correct turn responses.
