基于工作记忆内容的视觉注意

视觉系统是一个资源有限的信息加工系统, 在任何时刻视觉注意只能选择外界环境中的有限信息进行加工。工作记忆对于解决视觉场景中不同物体之间的注意竞争具有重要作用, 保持在工作记忆中的物体表征会以自上而下的方式引导注意优先选择视场中与之匹配的物体。本文系统回顾了有关工作记忆内容对视觉注意的引导作用的研究文献, 并探讨了基于工作记忆内容的视觉注意捕获的自动性, 指出基于工作记忆内容的视觉注意捕获是一个有条件的自动化过程。

Content-based Working Memory-driven Visual Attention

Since there are usually much more stimuli in the scene than limited capacity visual system can process at any moment,visual attention selects only a minority of them for further processing. Working memory (WM) may be crucial to resolve the competition for selection amongst different stimuli in the visual field. Top-down feedback from the representation held in WM will bias attention in favor of the matching objects. The present paper systematically reviews existing literature on top-down guidance of visual ...
