在整个发展过程中，源记忆表现的改善被认为是由促进任务相关信息检索的策略过程介导的。使用事件相关电位（ERP），我们研究了这些过程中的发展变化在青春期。青少年（13-14岁）和成年人（19-29岁）完成了一个记忆排除任务，要求在两种条件下，把不同的要求，在一种颜色（“目标”）和另一种颜色（“非目标”）研究的单词之间的歧视战略控制。记忆准确性随着年龄的增长而提高，并且随着两个年龄组控制需求的减少而增加。顶叶旧/新效应，ERP相关的回忆，是可靠的目标在两个年龄组的条件。相比之下，非目标回忆的ERP相关性存在于青少年的各种条件下，但在成年人中没有。这表明，成年人实施的策略，优先回忆的目标信息，更大的成功比青少年，无论控制需求，大概反映了成熟的认知控制的差异。为了支持这一观点，目标和非目标之间的ERP幅度差异与成年人的工作记忆容量（WMC）呈正相关，但在青少年中则不然。另一个与年龄相关的差异是，ERP相关的后检索处理，包括晚期右额叶旧/新的影响和晚期后负，只在成年人中观察到。总之，我们的数据表明，在选择性回忆和检索后控制的基础上，战略过程的长期成熟。
Improvement in source memory performance throughout development is thought to be mediated by strategic processes that facilitate the retrieval of task-relevant information. Using event-related potentials (ERPs), we examined developmental changes in these processes during adolescence. Adolescents (13-14 years) and adults (19-29 years) completed a memory exclusion task which required the discrimination between words studied in one color ('targets') and words studied in the alternative color ('non-targets') under two conditions that put different demands on strategic control. Memory accuracy improved with age and also increased with decreasing control demands in both age groups. The parietal old/new effect, an ERP correlate of recollection, was reliable for targets across conditions in both age groups. By contrast, ERP correlates of non-target recollection were present in adolescents across conditions but not in adults. This suggests that adults implemented a strategy to prioritize recollection of target information with greater success than adolescents regardless of control demands, presumably reflecting maturational differences in cognitive control. In support of this view, the ERP amplitude difference between targets and non-targets was positively correlated with a measure of working memory capacity (WMC) in adults but not in adolescents. A further age-related difference was that ERP correlates of post-retrieval processing, including late right-frontal old/new effects and late posterior negativities, were observed in adults only. Together, our data suggest protracted maturation in the strategic processes that underlie selective recollection and post-retrieval control.
