如果我们要研究人类的形状和空间知觉的发展，就有必要了解一些发育中的人类婴儿的基本视觉能力。在生命的最初几个月里，已经有许多关于视力的调查。Fantzet al.1使用固定偏好作为衡量标准，表明婴儿在1个月时可以辨别每度1.5个周期的条纹图案，在2个月时可以辨别每度3个周期的条纹图案。Dayton等发现新生儿的视动性眼球震颤为每度4个周期。这些研究表明，非常小的婴儿的视觉空间分辨率是有用的，尽管明显低于典型的成人值40周每度。
IF we are to study the development of form and space perception in man, it is necessary to know something of the basic visual capabilities of the developing human infant. There have been a number of investigations of visual acuity in the first few months of life. Using fixation preference as a measure, Fantzet al.1showed that infants could discriminate a stripe pattern of 1.5 cycles per degree by 1 month, and 3 cycles per degree by 2 months. Daytonet al.2found that newborn infants showed optokinetic nystagmus to a 4 cycles per degree pattern. These studies demonstrate a useful degree of visual spatial resolution in very young infants, though one markedly poorer than the typical adult value of 40 cycles per degree.
