The relationship between attention and eye movements is explored by consideration of the variety of ways attention may affect saccade programming. Four forms of attention are distinguished: one exogenous and three endogenous through either locations or objects or features. Each of these can control or influence the saccadic generation process. Visual onsets generate a rapid transient signal with low resolution that travels from the visual system to the oculomotor system. Generation of an eye movement is associated with an attentional signal, probably also with low resolution, travelling from the oculomotor system to the visual system. A high-resolution attentional signal, which appears to require voluntary effort, can also select saccadic targets.
通过考虑注意力影响扫视编程的各种方式，来探究注意力与眼动之间的关系。区分出四种注意力形式：一种是外源性的，另外三种是通过位置、物体或特征的内源性注意力。这些形式中的每一种都可以控制或影响扫视生成过程。视觉起始会产生一个低分辨率的快速瞬态信号，该信号从视觉系统传输到动眼系统。眼动的产生与一个注意力信号相关联，该信号可能也是低分辨率的，从动眼系统传输到视觉系统。一个似乎需要自主努力的高分辨率注意力信号，也可以选择扫视目标。
