视觉工作记忆表征与视觉注意的关系

The Relationship between Visual Working Memory Representations and Visual Attention

摘要: 视觉工作记忆表征与视觉注意之间存在密切联系，了解两者之间的关系对进一步理解视觉工作记忆表征的维持有重要意义。基于已有研究，本文分别梳理了视觉工作记忆表征对视觉注意的影响，视觉注意对视觉工作记忆表征的影响，以及两者之间相互作用的神经机制，发现视觉工作记忆中存储的内容可以捕获或抑制视觉注意，而视觉注意可以促进或干扰视觉工作记忆表征的精确性，且两者之间存在重叠的大脑皮层区域发挥着作用。目前，解释两者之间关系的理论仍不够完善，相关的皮层区域如何独立或共同发挥作用以及视觉注意对视觉工作记忆表征影响的神经机制也尚不太明确。未来需要进一步扩充相关研究的理论，并侧重在神经学层面上的相关研究。

Abstract: There is a close connection between visual working memory representations and visual attention, and understanding the relationship between them is important for further understanding the maintenance of visual working memory representations. Based on the existing researches, this paper combs the effects of visual working memory representations on visual attention, the effects of visual attention on visual working memory representations, and the neural mechanisms underlying the interactions between them, respectively, and finds that the content stored in visual working memory can capture or inhibit visual attention, while visual attention can facilitate or interfere with the accuracy of visual working memory representations, and there are overlapping cortical regions between them that play a role. Currently, theories explaining the relationship between them are still underdeveloped, and the neural mechanisms underlying how the relevant cortical regions function independently or together and the effects of visual attention on visual working memory representations are not clear. Future research needs to further expand the theories and focus on the neurological aspects of these studies.
