在观看了一幅环境图片后，我们对它的记忆通常会超出所呈现的内容，这种现象被称为边界扩展。但是，有时记忆错误会表现出相反的模式边界收缩，而这些现象之间的关系是有争议的。我们构建了虚拟三维环境，并在不同的距离创建了一系列视图，从物体特写到广角室内视图，并测试了沿着这个物体到场景的连续体的记忆错误。边界扩展是明显的近尺度的意见和参数化过渡到边界收缩远尺度的意见。然而，该转变点并不与环境中的特定位置相关联（例如，可达性点）。相反，它跟踪的是对环境中最好看的视图的判断，无论是在丰富的对象还是低对象环境中。我们提供了一个动态的张力帐户，基于对象和基于场景的启示之间的竞争决定了一个视图是否会在内存中扩展或收缩。这项研究表明，边界扩展和边界收缩不是两个独立的现象，而是一个连续体的两个部分，提出了一个共同的潜在机制。两者之间的过渡点不是固定的，而是取决于观察者对环境的最佳视角的判断。这些发现为我们如何感知和记忆环境提供了新的见解。
After viewing a picture of an environment, our memory of it typically extends beyond what was presented, a phenomenon referred to as boundary extension. But, sometimes memory errors show the opposite pattern—boundary contraction—and the relationship between these phenomena is controversial. We constructed virtual three-dimensional environments and created a series of views at different distances, from object close-ups to wide-angle indoor views, and tested for memory errors along this object-to-scene continuum. Boundary extension was evident for close-scale views and transitioned parametrically to boundary contraction for far-scale views. However, this transition point was not tied to a specific position in the environment (e.g., the point of reachability). Instead, it tracked with judgments of the best-looking view of the environment, in both rich-object and low-object environments. We offer a dynamic-tension account, where competition between object-based and scene-based affordances determines whether a view will extend or contract in memory. This study demonstrates that boundary extension and boundary contraction are not two separate phenomena but rather two parts of a continuum, suggesting a common underlying mechanism. The transition point between the two is not fixed but depends on the observer's judgment of the best-looking view of the environment. These findings provide new insights into how we perceive and remember a view of environment.
