A growing body of research suggests that performing actions can distort the perception of size, distance, and other visual information. These distortions have been observed under a variety of circumstances, and appear to persist in both perception and memory. However, it is unclear whether these distortions persist as observers move to new viewpoints. To address this issue, the present study assessed whether action-specific distortions persist across changes in viewpoint. Participants viewed an object that was projected onto a table, then reached for it with their index finger or a reach-extending tool. After reaching for the object, participants remained stationary or moved to a new viewpoint, then estimated the object’s distance from their current viewpoint. When participants remained stationary, using a reach-extending tool led them to report shorter distance estimates. However, when participants moved to a new viewpoint, these distortions were eliminated. Similar effects were observed when participants produced different types of movement, including when participants rotated in place, moved to a new location, or simply walked in place. Together, these findings suggest that action-specific distortions are eliminated when observers move and perform other actions.

跨现实观点变化更新感知和行动。

越来越多的研究表明，执行动作会扭曲大小，距离和其他视觉信息的感知。这些变形已在各种情况下被观察到，并且似乎持续存在于感知和记忆中。但是，不清楚的是，随着观察者转向新观点，这些扭曲是否还会持续下去。为了解决这个问题，本研究评估了特定于行动的失真是否在观点变化中仍然存在。参与者查看了一个投影到桌子上的对象，然后用食指或延伸工具将其伸到桌子上。到达对象后，参与者保持静止不动或移至新的视点，然后从其当前视点估计对象的距离。当参与者静止不动时，使用覆盖范围扩展工具导致他们报告更短的距离估算值。但是，当参与者转移到新的观点时，这些失真就消除了。当参与者产生不同类型的动作时，包括参与者旋转到位，移动到新位置或只是走到原处时，也会观察到类似的效果。总之，这些发现表明，当观察者移动并执行其他操作时，可以消除特定于操作的失真。
