视觉工作记忆和视觉注意密切相关，因此，工作记忆的编码和维护反映了对有限数量的视觉物体和事件的积极持续的注意，这些物体和事件对持续的认知和行动很重要。虽然注意力通常被认为是在知觉输入上运作的，但最近的一种分类法提出了额外的考虑，即在没有感官输入以及其他内部记忆、选择和思想的情况下，注意力如何被引导到内部知觉表征上（Chun, Golomb, & Turk-Browne, 2011）。这种内在的注意力使特征与综合对象的绑定时间延长，同时增强了相关的感觉机制。尽管不同类型的工作记忆和注意力（如空间处理和对象处理）各自独立运作，但这些过程的容量都是有限的。总的来说，维持的成功取决于抑制外部（知觉）和内部（认知）分心的能力。工作记忆是注意机制选择并积极维持来自外部世界的相关知觉信息作为大脑内部表征的接口。(C) 2011出版的爱思唯尔有限公司
Visual working memory and visual attention are intimately related, such that working memory encoding and maintenance reflects actively sustained attention to a limited number of visual objects and events important for ongoing cognition and action. Although attention is typically considered to operate over perceptual input, a recent taxonomy proposes to additionally consider how attention can be directed to internal perceptual representations in the absence of sensory input, as well as other internal memories, choices, and thoughts (Chun, Golomb, & Turk-Browne, 2011). Such internal attention enables prolonged binding of features into integrated objects, along with enhancement of relevant sensory mechanisms. These processes are all limited in capacity, although different types of working memory and attention, such as spatial vs. object processing, operate independently with separate capacity. Overall, the success of maintenance depends on the ability to inhibit both external (perceptual) and internal (cognitive) distraction. Working memory is the interface by which attentional mechanisms select and actively maintain relevant perceptual information from the external world as internal representations within the mind.
