工作记忆表征引导视觉注意的影响因素

Factors Influencing the Attentional Guidance from Working Memory Representations

摘要: 日常生活中人们每天都会通过视觉系统接受大量的刺激，而视觉系统是一个有限的信息加工系统，只能通过视觉注意在视觉场景中选择出与当前任务相关的信息做进一步加工。保持在工作记忆中的目标表征会影响视觉注意的选择，这种自上而下的注意引导被称作工作记忆表征对视觉注意的引导效应。在以往的研究中，并不总是能够观察到工作记忆表征对视觉注意的引导效应，引导效应的产生需要满足一定的条件。本文系统地总结了在过去的研究中发现的各种影响工作记忆表征对视觉注意的引导是否能够产生的因素，并对未来的研究作了展望。

Abstract: Every day people use the visual system to accept a lot of stimulations, and the visual system is a limited information processing system. People can only select the information that is related to current task through visual attention in the visual scene for further processing. Maintaining the target representation in working memory affects the selection of visual attention, which is called the guidance effect of visual attention from working memory representations. In previous studies, it is not always possible to observe the guidance effect, and the happening of guidance effect needs to meet certain conditions. We systematically summarize the factors that may influence the guidance effect of visual attention from working memory representations, and prospect the research in the future.
