The capacity of young infants to discriminate 3 x 3 degrees broadband red or 550 nm green squares from a 589 nm yellow surround was tested by means of the forced-choice preferential looking technique. All 3-month olds, about 3/4 of the 2-month olds, and just under half of the one-month-olds could make at least one of these discriminations. Taken together with other known properties of infant color vision, the failures of discrimination shown by the younger infants are more readily modeled as immaturities of neural processing than as an absence of anomaly of LWS or MWS cones.
通过强迫选择优先注视技术，测试了幼儿区分3×3度宽带红色或550纳米绿色方块与589纳米黄色背景的能力。所有3个月大的婴儿、约四分之三的2个月大的婴儿以及略少于一半的1个月大的婴儿，至少能做出其中一种区分。结合婴儿色觉的其他已知特性，较小婴儿表现出的辨别失败，更容易被建模为神经处理的不成熟，而不是长波敏感（LWS）或中波敏感（MWS）视锥细胞的异常缺失。
