Two- to 8-month-old infants interacted with their mother or a stranger in a prospective longitudinal gaze following study. Gaze following, as assessed by eye tracking, emerged between 2 and 4 months and stabilized between 6 and 8 months of age. Overall, infants followed the gaze of a stranger more than they followed the gaze of their mothers, demonstrating a stranger preference that emerged between 4 and 6 months of age. These findings do not support the notion that infants acquire gaze following through reinforcement learning. Instead, the findings are discussed with respect to the social cognitive framework, suggesting that young infants are driven by social cognitive motives in their interactions with others.
在一项前瞻性纵向目光追随研究中，2 至 8 个月大的婴儿与他们的母亲或陌生人进行互动。通过眼动追踪评估，目光追随在 2 至 4 个月之间出现，并在 6 至 8 个月之间稳定下来。总的来说，婴儿追随陌生人的目光比追随母亲的目光多，这表明从 4 至 6 个月大开始，婴儿出现了对陌生人的偏好。这些发现并不支持婴儿通过强化学习来获得目光追随的观点。相反，这些发现是根据社会认知框架来讨论的，这表明幼儿在与他人互动时受到社会认知动机的驱动。
