使用接触透镜/光学杠杆系统记录了与保持注视相关的单眼眼球运动。磁带上的模拟记录随后被转换成数字形式，并在计算机上进行分析。发现同一受试者在不同日期的反应之间存在合理的一致性。扫视和漂移的幅度和首选方向及其相互关系的分析表明，有一个椭圆形的整体固定区域，细分为一系列重叠的短期固定区域。结果表明，在注视过程中发生的扫视有两个功能之一，要么（a）重新集中在短期平均注视位置上的视网膜图像，或（B）移动短期注视区，可能是为了避免视网膜感受器疲劳。通过对实验结果的分析，提出了固视控制系统的组织模型。
The monocular eye movements associated with the maintenance of fixation have been recorded using the contact lens/optical lever system. The records, in analogue form on magnetic tape, were subsequently converted to a digital form and analysed on a computer. It is found that there is reasonable agreement between the responses of the same subject on different days. Analysis of the magnitudes and preferred directions of saccades and drifts and their interrelationships show that there is an elliptical overall fixation area which is subdivided into a series of overlapping short-period fixation areas. The results indicate that saccades occurring during fixation have one of two functions, either (a) to recentre the retinal image on the short-period mean fixation position, or (b) to move the short-period fixation area, possibly to avoid retinal receptor fatigue. An organizational model of the fixation control system has been developed from the analysis of results.
