66名大学生阅读了当代小说的两章，同时他们的眼球运动被监测。眼动数据进行了分析，以确定影响读者的初始眼睛固定在一个词的位置的因素。当数据根据先前固定的位置（即发射点）进行分区时，单词上固定位置的分布（即着陆点分布）受到高度约束，形状正常，并且不受单词长度的影响。对单词的初始注视位置可以根据知觉-眼动控制的五个原则来解释：单词对象具有特定的功能目标位置，出现扫视范围误差，其产生着陆点与功能目标位置的系统偏差，对于跟随较长眼睛注视的扫视，扫视范围误差稍微减小，存在着作为着陆点变化的第二个非系统性来源的感知-视力变化，并且感知-视力变化随着发射点距目标的距离而增加。
Sixty-six college students read two chapters from a contemporary novel while their eye movements were monitored. The eye movement data were analyzed to identify factors that influence the location of a reader's initial eye fixation on a word. When the data were partitioned according to the location of the prior fixation (i.e. launch site), the distribution of fixation locations on the word (i.e. landing site distribution) was highly constrained, normal in shape, and not influenced by word length. The locations of initial fixations on words can be accounted for on the basis of five principles of perceptuo-oculomotor control: a word-object has a specific functional target location, a saccadic range error occurs that produces a systematic deviation of landing sites from the functional target location, the saccadic range error is reduced somewhat for saccades that follow longer eye fixations, there exists perceptuo-oculomotor variability that is a second, nonsystematic source of variation in landing sites, and the perceptuo-oculomotor variability increases with distance of the launch site from the target.
