视觉注意是视觉感知的基础。空间注意使我们能够优先处理和选择性地处理给定位置的信息。在本文中,我解释了两种空间注意:隐蔽注意(分配到目标位置,没有伴随的眼动)和预视注意(分配到即将到来的扫视目标的位置)如何影响性能和改变外观。首先,我重点介绍了一些关于隐蔽注意力的行为和神经成像研究,它会改变许多基本视觉任务中的表现和外表。其次,我回顾了一些研究,这些研究表明眼跳前注意可以改善眼跳目标位置的表现并改变其外观。此外,这些调制自动改变特征信息的处理,即使它对手头的任务有害。我们认为,眼跳准备可能支持跨视整合。系统地研究内隐注意和视前注意的共性和差异性,将继续加深我们对信息的普遍选择性加工的理解,使我们能够理解我们复杂的视觉世界。
Visual attention is essential for visual perception. Spatial attention allows us to grant priority in processing and selectively process information at a given location. In this paper, I explain how two kinds of spatial attention: covert (allocated to the target location, without accompanying eye movements) and presaccadic (allocated to the location of the upcoming saccade’s target) affect performance and alter appearance. First, I highlight some behavioral and neuroimaging research on covert attention, which alters performance and appearance in many basic visual tasks. Second, I review studies showing that presaccadic attention improves performance and alters appearance at the saccade target location. Further, these modulations change the processing of feature information automatically, even when it is detrimental to the task at hand. We propose that saccade preparation may support transaccadic integration. Systematically investigating the common and differential characteristics of covert attention and presaccadic attention will continue to further our understanding of the pervasive selective processing of information, which enables us to make sense of our complex visual world.
