Research on visual development has long been guided by two hypotheses: visual development is complete during infancy and the different visual functions (e.g., contrast sensitivity, acuity, motion perception, form perception) mature at the same rate. This explains why there are few studies of visual development beyond infancy. A series of recent studies from our laboratory cast serious doubt about these two hypotheses. Indeed, we found that several visual functions do not attain maturity before late childhood or even early adolescence and that not all visual functions mature at the same rate.

长期以来，关于视觉发育的研究一直受到两个假设的指导：视觉发育在婴儿期完成，不同的视觉功能（例如，对比敏感度、敏锐度、运动知觉、形状知觉）以相同的速率成熟。这就解释了为什么很少有关于婴儿期以后视觉发育的研究。我们实验室最近的一系列研究对这两个假设提出了严重的质疑。事实上，我们发现，有几种视觉功能在儿童晚期甚至青春期早期之前不会达到成熟，并且并非所有视觉功能都以相同的速度成熟。
