Infants have a natural tendency to look at adults' faces, possibly to help initiate vital interactions with caregivers during sensitive periods of development. Recent studies using eye‐tracking technologies have identified the mechanisms that underlie infants' capacity to orient and hold attention on faces. These studies have shown that the bias for faces is weak in young infants, but becomes more robust and resistant to distraction during the second half of the 1st year. This development is apparently related to more general changes in infants' attention and control of eye movement. As a tractable and reproducible aspect of infant behavior, the attention bias for faces can be used to examine the neural correlates of attention and may be a way to monitor early neurodevelopment in infants.

使用眼动追踪了解婴儿对面部的注意力偏差。

婴儿有看成人脸的自然倾向，这可能有助于在敏感的发育时期与看护人进行重要的互动。最近使用眼动追踪技术的研究已经确定了婴儿在面部定向和保持注意力能力的基础机制。这些研究表明，年幼婴儿对面孔的偏见较弱，但在第一年的后半期变得更加强大和抗干扰。这种发展显然与婴儿注意力和眼球运动控制的更普遍变化有关。作为婴儿行为的一个易于处理和可重复的方面，面部的注意力偏差可用于检查注意力的神经相关性，并且可能是监测婴儿早期神经发育的一种方式。
