Attention is a central neural process that enables selective and efficient processing of visual information. Individuals can attend to specific visual information either overtly, by making an eye movement to an object of interest, or covertly, without moving their eyes. We review behavioral, neuropsychological, neurophysiological, and computational evidence of presaccadic attentional modulations that occur while preparing saccadic eye movements, and highlight their differences from those of covert spatial endogenous (voluntary) and exogenous (involuntary) attention. We discuss recent studies and experimental procedures on how these different types of attention impact visual performance, alter appearance, differentially modulate the featural representation of basic visual dimensions (orientation and spatial frequency), engage different neural computations, and recruit partially distinct neural substrates. We conclude that presaccadic attention and covert attention are dissociable.

注意力是一个中枢神经过程，可以选择性和有效地处理视觉信息。个人可以通过对感兴趣的对象进行眼球运动来公开地关注特定的视觉信息，或者在不移动眼睛的情况下隐蔽地关注特定的视觉信息。我们回顾了在准备扫视眼球运动时发生的扫视前注意调制的行为、神经心理学、神经生理学和计算证据，并强调了它们与隐蔽空间内源性（自愿）和外源性（非自愿）注意的区别。我们讨论了最近关于这些不同类型的注意力如何影响视觉表现、改变外观、差异调节基本视觉维度（方向和空间频率）的特征表示的研究和实验程序，参与不同的神经计算，并招募部分不同的神经基质。我们得出结论，presaccadic 注意和隐蔽注意是可分离的。
