人类婴儿出生后3-4个月出现立体视觉是惊人的，并导致推测其快速发病和随后的发展必须归因于大脑的戏剧性重组。立体视觉从未在幼猴中测量过，但以前的研究表明，许多其他视觉功能在幼猴中的发育速度是人类的四倍。我们对11只幼年恒河猴的立体视锐度进行了纵向评估。在测试过程中，使用了一种强制选择的偏好性技术来呈现随机点立体图。出生后8周，所有猴子都至少对粗略的视差水平（1760″ [秒]）做出反应，到13周龄时，所有猴子都对相对精细的88″视差水平做出反应。正如预期的那样，猴子的立体视觉发病年龄约为人类发病年龄的四分之一。然而，随后的发展在猴子和人类中以类似的绝对速度进行。相对于神经机制，这可能是负责不同的发展速度的研究结果进行了讨论。
The emergence of stereopsis at 3–4 months postnatal in human infants is striking and has led to speculation that its rapid onset and subsequent development must be due to a dramatic reorganization of the brain. Stereopsis has never been measured in infant monkeys, but previous studies have demonstrated that many other visual functions develop four times faster in infant monkeys than in humans. We made longitudinal assessments of stereoacuity in 11 infant rhesus monkeys. A forced-choice preferential-looking technique was used to present random-dot stereograms during testing. By 8 weeks after birth, all of the monkeys were responding to at least coarse levels of disparity (1760″ [seconds]), and by 13 weeks of age, all were responding to the relatively fine level of 88″ disparity. Age of onset for stereopsis in monkeys was at about one-quarter the age when it occurs in humans, as expected. However, subsequent development proceeded at a similar absolute rate in monkeys and humans. The findings are discussed relative to the neural mechanisms which might be responsible for the differing rates of development.
