Infants' learn a great deal about the physical world during the first year of life. There is a growing body of research investigating the conditions under which this is most likely to occur. Most of this research has focused on the type of information that infants are presented. The current research moves the field in a new direction by investigating the extent to which the social context--who presents the information to the infant--influences knowledge acquisition. Infants were first presented with a color-priming event in a non-social context (Experiment 1) or a social context (Experiment 2). These two contexts differed primarily in whether the individual presenting the color-priming events was behind the apparatus and hidden from view or sat next to the infant and was visible, respectively. The extent to which viewing the color priming events increased infants' sensitivity to color differences in a subsequent object individuation task was then assessed. The results revealed that whereas 8.5-month-olds experienced color priming in the non-social context, 7.5-month-olds only experienced color priming within a social context. Furthermore, the 7.5-month-olds evidenced priming only when their own parent, not an unfamiliar adult, was the social partner performing the priming events. This provides new evidence for the significance of infant learning within a social context and the potential role of parents.
婴儿在生命的第一年中会学到很多关于物理世界的知识。越来越多的研究正在调查最有可能发生这种情况的条件。这项研究的大部分重点都放在了婴儿所接受的信息类型上。当前的研究通过调查社会环境(谁向婴儿提供信息)对知识获取的影响,将该领域推向了一个新的方向。婴儿首先在非社会环境(实验 1)或社会环境(实验 2)中经历了颜色启动事件。这两种情况的主要区别在于呈现颜色启动事件的个体是在仪器后面并隐藏在视线之外,还是坐在婴儿旁边并可见。然后评估观看颜色启动事件在后续对象个体化任务中增加婴儿对颜色差异的敏感性的程度。结果表明,虽然 8.5 个月大的婴儿在非社会环境中经历了颜色启动,但 7.5 个月大的婴儿仅在社会环境中经历了颜色启动。此外,只有当自己的父母(而不是陌生的成年人)作为社会伙伴执行启动事件时,7.5 个月大的婴儿才表现出启动作用。这为社会环境中婴儿学习的重要性以及父母的潜在作用提供了新的证据。
