Abstract

The ability to perceive and remember the spatial layout of a scene is critical to understanding the visual world, both for navigation and for other complex tasks that depend upon the structure of the current environment. However, surprisingly little work has investigated how and when scene layout information is maintained in memory. One prominent line of work investigating this issue is a scene-priming paradigm (e.g., Sanocki & Epstein, 1997), in which different types of previews are presented to participants shortly before they judge which of two regions of a scene is closer in depth to the viewer. Experiments using this paradigm have been widely cited as evidence that scene layout information is stored across brief delays and have been used to investigate the structure of the representations underlying memory for scene layout. In the present experiments, we better characterize these scene-priming effects. We find that a large amount of visual detail rather than the presence of depth information is necessary for the priming effect; that participants show a preview benefit for a judgment completely unrelated to the scene itself; and that preview benefits are susceptible to masking and quickly decay. Together, these results suggest that "scene priming" effects do not isolate scene layout information in memory, and that they may arise from low-level visual information held in sensory memory. This broadens the range of interpretations of scene priming effects and suggests that other paradigms may need to be developed to selectively investigate how we represent scene layout information in memory.

摘要

感知和记忆场景的空间布局的能力对于理解视觉世界至关重要,无论是对于导航还是对于依赖当前环境结构的其他复杂任务而言。然而,令人惊讶的是,很少有研究探讨场景布局信息在记忆中是如何以及何时被保持的。研究这个问题的一个主要研究方向是场景启动范式(例如,Sanocki & Epstein,1997),在该范式中,在参与者判断场景的两个区域中哪个在深度上更靠近观察者之前不久,会向他们呈现不同类型的预览。使用该范式的实验被广泛引用,作为场景布局信息在短暂延迟期间被存储的证据,并已被用于研究场景布局记忆背后的表征结构。在本实验中,我们对这些场景启动效应进行了更好的表征。我们发现,启动效应需要大量的视觉细节而非深度信息的存在;参与者对与场景本身完全无关的判断表现出预览优势;并且预览优势容易受到掩蔽的影响且迅速衰退。总之,这些结果表明,“场景启动”效应并没有在记忆中分离出场景布局信息,并且它们可能源于感觉记忆中保留的低层次视觉信息。这拓宽了对场景启动效应的解释范围,并表明可能需要开发其他范式来选择性地研究我们如何在记忆中表征场景布局信息。
