North Dakota State University, Fargo, North Dakota Little is known about infants' perception of depth from motion parallax, even though it is known that infants are sensitive both to motion and to depth-from-motion cues at an early age. The present experiment assesses whether infants are sensitive to the unambiguous depth specified by motion parallax and, if so, when this sensitivity first develops. Eleven infants were followed longitudinally from 8 to 29 weeks. Infants monocularly viewed a translating Rogers and Graham (1979) random-dot stimulus, which appears as a corrugated surface to adult observers. Using the infant-control habituation paradigm, looking time was recorded for each 10-sec trial until habituation, followed by two test trials: one using a depth-reversed and one using a flat stimulus. Dishabituation results indicate that infants may be sensitive to unambiguous depth from motion parallax by 16 weeks of age. Implications for the developmental sequence of depth from motion, stereopsis, and eye movements are discussed.

婴儿运动视差引起的深度感知的发展。

北达科他州立大学，北达科他州法戈，尽管人们知道婴儿在很小的时候就对运动以及对运动深度的暗示都敏感，但对婴儿对运动视差的深度知之甚少。本实验评估婴儿是否对运动视差指定的明确深度敏感，如果是，则何时开始发展这种敏感性。纵向随访11至8周至29周。婴儿单眼观看了翻译的罗杰斯和格雷厄姆（Rogers and Graham，1979）的随机点刺激，对成年观察者来说，它是波纹表面。使用婴儿控制习惯模型，记录每10秒钟试验的观察时间，直到适应为止，然后进行两项试验：一项使用深度反转，另一项使用平坦刺激。身体不适的结果表明，到16周龄时，婴儿可能会对运动视差明确的深度敏感。讨论了从运动，立体视和眼球运动到深度发展顺序的含义。
