注视性眼球运动被细分为震颤、漂移和微扫视。所有三种类型的微型眼球运动产生小随机位移的视网膜图像时，观看一个静止的场景。在这里，我们研究了经典的空间线索范式下的内隐注意转移对微眼跳的调制。首先，我们复制的抑制微扫视的最小速率约150毫秒后，线索发病。第二，作为一个新的发现，我们观察到微扫视增强的最大速率约350毫秒后，介绍的线索。第三，我们发现一个调制的方向朝向线索的方向。视觉注意对微眼跳的多重影响突出了其在视觉信息处理中的作用。此外，我们的研究结果表明，微眼跳可以用来映射视觉注意的心理物理实验的方向。(C)2003爱思唯尔科技有限公司版权所有。
Fixational eye movements are subdivided into tremor, drift, and microsaccades. All three types of miniature eye movements generate small random displacements of the retinal image when viewing a stationary scene. Here we investigate the modulation of microsaccades by shifts of covert attention in a classical spatial cueing paradigm. First, we replicate the suppression of microsaccades with a minimum rate about 150 ms after cue onset. Second, as a new finding we observe microsaccadic enhancement with a maximum rate about 350 ms after presentation of the cue. Third, we find a modulation of the orientation towards the cue direction. These multiple influences of visual attention on microsaccades accentuate their role for visual information processing. Furthermore, our results suggest that microsaccades can be used to map the orientation of visual attention in psychophysical experiments. (C) 2003 Elsevier Science Ltd. All rights reserved.
