在理论上最佳的条件下，对9周和20周大的人类婴儿的颜色恒定性进行了检测。在彩色监视器上模拟了两组具有互补反射功能的自然表面，它们被两种不同的太阳光照射。每个年龄段的婴儿的最终样本只包括那些在8个熟悉试验中表现出最大习惯化证据的婴儿。20周龄的婴儿只对表面反射率的模拟变化做出更多的关注，而不是只对照明的模拟变化做出反应。然而，9周大的婴儿对光源或表面反射率的模拟变化的关注程度有所增加。考虑到9周龄和20周龄之间可能存在的光谱敏感度差异，并拒绝将其作为颜色恒定的年龄差异的解释。
Color constancy was examined in 9- and 20-week-old human infants under theoretically optimal conditions. Pairs of natural surfaces with complementary reflectance functions, illuminated with two different phases of sunlight, were simulated on a color monitor. The final sample of infants of each age included only those infants who showed the greatest evidence of habituation during the 8 familiarization trials. The 20-week-olds responded with increased attention only to simulated changes of surface reflectance and not to simulated changes of the illumination alone. However, 9-week-olds responded with increased attention to simulated changes either of the illuminant or of surface reflectance. Possible differences in spectral sensitivity between 9 and 20 weeks of age were considered and rejected as explanation for the age difference in color constancy.
