几个研究小组已经确定了成年人大脑皮层的一个区域网络，这些区域在社会感知和认知任务中被激活。在本文中，我们专注于这个社会的大脑网络的组件在幼儿期的发展和测试方面的一个特定的观点对人类功能的大脑发展：“互动专业化。“具体来说，我们将新的数据分析技术应用于先前发表的事件相关电位（ERP）研究数据集，这些研究涉及3个月、4个月和12个月大的婴儿，他们观察不同方向和眼睛注视方向的面孔。使用源分离和定位方法，头皮记录ERP的几个可能的发电机被确定，我们描述了它们是如何调制的刺激特性。然后，我们回顾了一系列关于眼睛注视的感知和行动的实验结果，然后报告了一项涉及自闭症儿童的新实验。最后，我们将讨论基于社会脑网络的非典型出现的预测。
Several research groups have identified a network of regions of the adult cortex that are activated during social perception and cognition tasks. In this paper we focus on the development of components of this social brain network during early childhood and test aspects of a particular viewpoint on human functional brain development: "interactive specialization." Specifically, we apply new data analysis techniques to a previously published data set of event-related potential (ERP) studies involving 3-, 4-, and 12-month-old infants viewing faces of different orientation and direction of eye gaze. Using source separation and localization methods, several likely generators of scalp recorded ERP are identified, and we describe how they are modulated by stimulus characteristics. We then review the results of a series of experiments concerned with perceiving and acting on eye gaze, before reporting on a new experiment involving young children with autism. Finally, we discuss predictions based on the atypical emergence of the social brain network.
