视觉注意是选择相关视觉信息而忽略不相关视觉信息的机制集合。视觉工作记忆是相关的视觉信息被保留，而不相关的信息被抑制的机制。除了定义上的重叠之外，在注意力和工作记忆任务中活跃的大脑区域也有很强的重叠。本文回顾了支持和反对“视觉工作记忆和注意是同一种认知功能，具有相同的能力、相同的控制过程和相同的表征内容”这一假设的行为证据。数据最好由一个统一的模型来解释，在这个模型中可以保持多个表示，但只有一个受到当前关注的焦点。然后，任务环境决定了这个中心表征比它的助记符竞争者优先级高的程度。
Visual attention is the collection of mechanisms by which relevant visual information is selected, and irrelevant visual information is ignored. Visual working memory is the mechanism by which relevant visual information is retained, and irrelevant information is suppressed. In addition to this overlap in definition, a strong overlap in brain areas active during attention and working memory tasks is found. The present paper reviews the behavioral evidence for and against the hypothesis that visual working memory and attention are best regarded as one and the same cognitive function, with the same capacity, the same control processes, and the same representational content. The data are best explained by a unified model in which multiple representations can be maintained, but only one receives the current focus of attention. Task circumstances then determine how successful this central representation can be prioritized over its mnemonic competitors.
