全局背景在视觉任务中起着重要但知之甚少的作用。这项研究表明，存在一个强大的视觉背景记忆来引导空间注意。全局上下文被操作化为视觉搜索显示中对象的空间布局。在整个会话中，有一半的配置在块之间重复，目标出现在这些阵列中的一致位置。出现在学习配置中的目标被更快地检测到。这种新发现的搜索促进形式被称为上下文提示。背景线索是由偶然学到的空间配置（上下文）和目标位置之间的关联驱动的。尽管识别配置的机会表现，但仍获得了这种益处，这表明上下文记忆是内隐的。研究结果表明，视觉环境的内隐学习和记忆如何引导空间注意力朝向场景的任务相关方面。(C)北京：科学出版社.
Global context plays an important, but poorly understood, role in visual tasks. This study demonstrates that a robust memory for visual context exists to guide spatial attention. Global context was operationalized as the spatial layout of objects in visual search displays. Half of the configurations were repeated across blocks throughout the entire session, and targets appeared within consistent locations in these arrays. Targets appearing in learned configurations were detected more quickly. This newly discovered form of search facilitation is termed contextual cueing. Contextual cueing is driven by incidentally learned associations between spatial configurations (context) and target locations. This benefit was obtained despite chance performance for recognizing the configurations, suggesting that the memory for context was implicit. The results show how implicit learning and memory of visual context can guide spatial attention towards task-relevant aspects of a scene. (C) 1998 Academic Press.
