In this chapter, we describe the role of attention in the control of smooth pursuit eye movements. As a voluntary and continuous eye movement, smooth pursuit is driven by both visual and cognitive signals. Here we show that whereas the entire process of smooth pursuit requires visual attention, the post-onset phase of the initiation and the maintenance smooth pursuit are under an additional sustained non-visual cognitive attention control. The temporal dynamics of these complementary controls of visual and non-visual cognitive attention support the continuous generation of smooth pursuit so that eye tracking of a moving target can be prompt and accurate.
在本章中，我们描述了注意力在平稳跟踪眼球运动控制中的作用。作为一种自主且持续的眼球运动，平稳跟踪由视觉和认知信号共同驱动。我们在此表明，虽然平稳跟踪的整个过程都需要视觉注意力，但起始和平稳跟踪维持的起始后阶段还受到额外的持续非视觉认知注意力控制。视觉和非视觉认知注意力的这些互补控制的时间动态支持平稳跟踪的持续产生，从而使对移动目标的眼球跟踪能够迅速且准确。
