For effective human vision, the brain must integrate the binocular input from the two eyes, and in turn drive the two eyes to move binocularly in appropriate directions. The development of sensory binocularity appears to depend on the ability to align the two eyes to give visual stimulation of corresponding points on the retina of each eye. This alignment is a precursor to development of cells in the visual cortex that are sensitive to retinal disparity, and for stereoscopic vision. This project studies how oculomotor and sensory factors combine to contribute to the development of binocular visual functions during infancy in humans. Models are outlined for possible developmental relationships, and a novel binocular eye-tracking technique will be used to measure human infant eye movements. Data on developing motor binocularity is compared to data on developing sensory binocularity measured by a variety of behavioral and non-invasive tests, to see how sensory and motor factors are combined. Results from this study will be important to visual science, and also to developmental human research and to human performance analysis, with further likely importance to understanding disorders in binocular vision. ***

为了有效的人类视觉，大脑必须整合来自两只眼睛的双眼输入，并反过来驱动两只眼睛在适当的方向上进行双眼运动。 感觉双眼的发展似乎取决于将两只眼睛对齐以给予每只眼睛视网膜上的对应点的视觉刺激的能力。 这种排列是视觉皮层中对视网膜视差敏感的细胞和立体视觉发育的前兆。 本计画主要研究人类婴儿期双眼视觉功能的发展，是如何由视觉与感觉联合收割机所促成。 模型概述了可能的发展关系，和一种新的双目眼跟踪技术将被用来测量人类婴儿的眼球运动。 发展中的运动双目的数据进行比较，发展中的感官双目的各种行为和非侵入性测试测量的数据，看看感觉和运动因素是如何结合起来的。 这项研究的结果将是重要的视觉科学，也发展人类的研究和人类的性能分析，进一步可能的重要性，了解疾病的双眼视觉。 ***
