Ongoing experience unfolds over time. To segment continuous experience into component events, humans rely on physical and conceptual boundaries. Here we explored the subjective representation of turns along travelled routes as boundaries. Across two experiments, turns selectively enhanced participants’ subjective recollection of locations immediately preceding them, compared to their recollection of locations in the middle of a route straightaway or immediately following turns. In Experiment 2, we also observed a subjective expansion of the time spent at pre-turn, relative to post-turn, locations. These results highlight the influence of turns on memory for travelled routes and provide further evidence for a link between subjective episodic re-experiencing and temporal memory. Taken together, this evidence suggests that turns during navigation act much as boundaries do for events, enhancing memory and processing of pre-boundary locations.

导航期间的转弯充当边界,可增强空间记忆并扩展时间估计。

持续的经验会随着时间的推移而发展。为了将连续的体验划分为各个组成部分,人类需要依靠物理和概念上的界限。在这里,我们探索了以行驶路线为边界的转弯的主观表现形式。在两个实验中,转弯有选择地增强了参与者对自己紧随其后的位置的主观回忆,与之相比,他们对路线中间或转弯后立即回想的位置的回忆。在实验2中,我们还观察到相对于转弯后位置而言,转弯前所花费时间的主观扩展。这些结果突显了转弯对行进路线记忆的影响,并为主观情节性再体验与时间记忆之间的联系提供了进一步的证据。在一起
