从出生起，婴儿就更喜欢看脸，而不是乱七八糟的脸。这种面孔输入对面孔加工的发展很重要：由于先天性白内障而经历早期视觉剥夺的人，会有长期的面孔加工缺陷。有趣的是，这种缺陷是特定于眼睛的，因此左眼白内障会干扰面部加工的发展，而右眼白内障则不会。这就提出了一个问题，婴儿的脸部偏好是否主要是由左眼观察到的面孔驱动的。为了研究这一点，我们展示了3个月大的婴儿，他们的脸是完整的，有杂乱的脸。婴儿只用左眼或右眼用双眼观察运动刺激。用双眼或只用左眼看刺激的婴儿比看杂乱的脸花费更多的时间看完整的脸，但这种效果在只用右眼看刺激的婴儿中是模棱两可的。双眼组的婴儿对面孔的偏好最大，而且这种偏好大于右眼组对面孔的偏好。左眼组对面孔的偏好与其他两组的面孔偏好在统计学上没有差异，但进一步的分析显示，只有右眼组的面孔偏好与年龄之间存在相关性，这表明右眼组对面孔的偏好从3个月到4个月增加。这些结果表明，在3个月大或之前，左眼在面孔加工中发挥着特殊的作用，但在3个月大后不久，人们就出现了通过右眼加工面孔的偏好。
From birth, infants prefer looking at faces over scrambled faces. This face input is important for the development of face processing: individuals who experienced early visual deprivation due to congenital cataracts have long-lasting face processing deficits. Interestingly, the deficits are eye-specific such that left eye cataracts disrupt the development of face processing whereas right eye cataracts do not. This raises the question of whether infant face preferences are driven primarily by faces observed through the left eye. To investigate this, we presented 3-month-old infants with intact faces paired with scrambled faces. Infants viewed the moving stimuli binocularly, only with their left eye, or only with their right eye. Infants viewing stimuli binocularly or with only the left eye spent significantly more time looking at intact faces than scrambled faces, but this effect was equivocal in infants viewing stimuli through only their right eye. Infants in the binocular group had the greatest preference for faces, and this preference was greater than the right eye group’s preference for faces. The left eye group’s preference for faces was not statistically different from the other two groups’ preference for faces, but additional analyses revealed a correlation between preference for faces and age for the right eye group only, indicating that preference for faces seen with the right eye increase from 3- to 4-months-of-age. These results indicate that the left eye plays a special role in face processing at, or before 3-months-of-age, but a preference for faces through the right eye emerges soon after.
