记忆在成人和学龄儿童中都有很好的特点，但对这种能力在儿童早期是如何发展的却知之甚少。本研究采用行为来源记忆范式和事件相关电位(ERPs)来考察儿童早期的回忆。将上下文被记住和忘记的项目以及新项目之间的事件相关电位进行比较。电生理反应后期的活动表现出一种“回忆”效应，这种效应将来源判断正确的项目与所有其他项目区分开来。这项研究是独一无二的，因为它是第一次提供关于童年早期记忆基础神经网络的时空动力学信息。
Recollection is well-characterized in adults and school-aged children, yet little is known about how this ability develops in early childhood. This study utilized a behavioral source memory paradigm and event-related potentials (ERPs) to examine recollection in early childhood. ERPs were compared between items whose context was remembered and forgotten as well as new items. Activity late in the electrophysiological response showed a “recollection” effect, which differentiated items with correct source judgments from all others. This study is unique in that it is the first to provide information regarding the spatiotemporal dynamics of the neural networks underlying recollection during early childhood.
