眼跳运动和知觉注意以一种协调的方式工作，以允许选择对有限的视觉处理资源具有最大瞬时需求的对象、特征或区域。这项研究使用视觉操作来研究保持注视过程中的注意机制，调查了一系列眼跳过程中眼跳前注意转移的知觉特征。本文第一部分回顾了眼跳与注意之间关系的研究，以及它们对眼跳控制和知觉的意义。第二部分介绍了三个实验，考察了眼跳前注意转移对眼跳序列中视觉的影响。在一系列刺激对比中，无论是知觉辨别还是检测任务，无论是单个还是多个知觉目标，无论是否存在外部噪声，眼跳目标位置相对于非目标位置的知觉增强都被发现。结果表明，眼跳的准备可以引起多种注意效应，包括注意介导的知觉表征强度的变化，视觉记忆中编码目标的选择，外部噪声的排除，或内部视觉噪声水平的变化。由眼跳规划引起的视觉变化使视觉系统能够有效地利用眼跳运动来探索视觉环境。
Saccadic eye movements and perceptual attention work in a coordinated fashion to allow selection of the objects, features or regions with the greatest momentary need for limited visual processing resources. This study investigates perceptual characteristics of pre-saccadic shifts of attention during a sequence of saccades using the visual manipulations employed to study mechanisms of attention during maintained fixation. The first part of this paper reviews studies of the connections between saccades and attention, and their significance for both saccadic control and perception. The second part presents three experiments that examine the effects of pre-saccadic shifts of attention on vision during sequences of saccades. Perceptual enhancements at the saccadic goal location relative to non-goal locations were found across a range of stimulus contrasts, with either perceptual discrimination or detection tasks, with either single or multiple perceptual targets, and regardless of the presence of external noise. The results show that the preparation of saccades can evoke a variety of attentional effects, including attentionally-mediated changes in the strength of perceptual representations, selection of targets for encoding in visual memory, exclusion of external noise, or changes in the levels of internal visual noise. The visual changes evoked by saccadic planning make it possible for the visual system to effectively use saccadic eye movements to explore the visual environment.
