视觉记忆已被证明在自然场景的视觉搜索和注意优先级中发挥作用。然而，它主要是在使用多个二维图像的实验范式中研究的。然而，自然体验需要长时间沉浸在有限的三维环境中。本实验的目的是重建与自然视觉体验相媲美的环境，以评估场景记忆在自然环境中指导眼球运动的作用。在为期三天的沉浸式虚拟现实环境中，受试者进行了连续的视觉搜索任务。我们发现，与二维环境类似，观众会随着时间的推移迅速了解环境中物体的位置，并利用空间记忆来指导搜索。附带注视对随后的搜索没有明显的好处，这表明语义上下文线索可能通常同样有效，或者在没有特定任务的情况下，许多附带注视的项目没有保存在记忆中。在体验环境的第三天，之前的搜索项的颜色发生了变化。相对于控制对象，这些项目被关注的可能性更高，这表明除了任务因素和简单的空间显著性外，记忆引导的优先级（或惊喜）可能是吸引人们关注自然环境新特征的强大机制。
Visual memory has been demonstrated to play a role in both visual search and attentional prioritization in natural scenes. However, it has been studied predominantly in experimental paradigms using multiple two-dimensional images. Natural experience, however, entails prolonged immersion in a limited number of three-dimensional environments. The goal of the present experiment was to recreate circumstances comparable to natural visual experience in order to evaluate the role of scene memory in guiding eye movements in a natural environment. Subjects performed a continuous visual-search task within an immersive virtual-reality environment over three days. We found that, similar to two-dimensional contexts, viewers rapidly learn the location of objects in the environment over time, and use spatial memory to guide search. Incidental fixations did not provide obvious benefit to subsequent search, suggesting that semantic contextual cues may often be just as efficient, or that many incidentally fixated items are not held in memory in the absence of a specific task. On the third day of the experience in the environment, previous search items changed in color. These items were fixated upon with increased probability relative to control objects, suggesting that memory-guided prioritization (or Surprise) may be a robust mechanisms for attracting gaze to novel features of natural environments, in addition to task factors and simple spatial saliency.
