采用事件相关电位（ERP）技术，考察了学龄儿童和成人熟悉性和回忆性对项目及其学习情境再认记忆的相对贡献。虽然成年人能够选择性地接受目标项目，并拒绝熟悉的非目标项目在所有排除任务，这种歧视是更困难的儿童，这是明显的高误报率nontargets，即使项目记忆控制。对成人ERP的分析揭示了更灵活和适合任务的提取机制，这在熟悉性、回忆、中期非目标提取以及事后评价的相关性中是明显的。与此相反，儿童的ERP揭示了顶叶的旧/新的效果作为一个假定的相关的回忆目标。这些研究结果表明，儿童主要依靠油的回忆在识别判断，即使在没有有效的记忆控制过程。后一个过程使成年人能够监测和验证检索到的信息，并控制非目标检索，以充分的源记忆性能。
Using event-related potentials (ERPs), we examined the relative contributions of familiarity and recollection to recognition memory for items and their study contexts in school-aged children and adults. Whereas adults were able to selectively accept target items and to reject familiar nontarget items in ail exclusion task, this discrimination was more difficult for children, as was evident in the high false alarm rates to nontargets even when item memory was controlled for. The analysis of the adults' ERPs revealed more flexible and task-appropriate retrieval mechanisms, as was evident in the correlates of familiarity, recollection, mid nontarget retrieval, as well as in postretrieval evaluation. In contrast, children's ERPs revealed a parietal old/new effect for targets taken as a putative correlate of recollection. These findings suggest that children rely predominantly oil recollection during recognition judgments, even in the absence of efficient memory control processes. The latter processes enable adults to monitor and verify the retrieved information and to control nontarget retrieval in the service of adequate source memory performance.
