生命早期，异常的视觉体验可能会扰乱正常视觉功能成熟和维持所需的发育过程。在恒河猴中研究了视网膜图像剥夺（单眼形式剥夺）对四种心理物理功能的影响，以确定所有类型的视觉信息处理的敏感期是否具有相同的持续时间。与单眼空间视觉或分辨率（25 个月）和双眼视觉（> 25 个月）等更复杂的功能相比，视杆细胞和视锥细胞的基本光谱灵敏度功能的敏感发展期相对较短（3 和 6 个月）。因此，存在多个、部分重叠的发育敏感期，并且每种特定视觉功能的敏感期可能不同。
Early in life, abnormal visual experience may disrupt the developmental processes required for the maturation and maintenance of normal visual function. The effects of retinal image deprivation (monocular form deprivation) on four psychophysical functions were investigated in rhesus monkeys to determine if the sensitive period is of the same duration for all types of visual information processing. The basic spectral sensitivity functions of rods and cones have relatively short sensitive periods of development (3 and 6 months) when compared to more complex functions such as monocular spatial vision or resolution (25 months) and binocular vision (> 25 months). Therefore, there are multiple, partially overlapping sensitive periods of development and the sensitive period for each specific visual function is probably different.
