从情景记忆中检索信息涉及检索前控制过程的参与,这些过程有助于恢复任务相关信息。本文通过比较13-14岁青少年和青年人的提取定向的神经相关来研究这些过程的发展。在每个年龄组中,事件相关电位(ERP)引起的新的测试图片进行了对比,在两个识别记忆任务(具体与一般检索任务),这是为了把更大的要求恢复知觉的信息与每个图片在具体的比在一般的任务。记忆准确性高于一般比在特定的任务,但没有年龄组之间的差异。在400 ~ 1200 ms的时间段内,成人前部新项目的ERP在特定任务中比一般任务中更积极。在青少年中,这种效应的起始潜伏期相对于成人延迟了300 ms,尽管在两项任务中均未获得反应速度的年龄差异。成年人的ERP新项目效应的大小与反应的准确性,一致的看法,即前检索过程有利于恢复任务相关的信息。对于青少年,这种关系只获得了一个子集的参与者与早期onseting ERP的影响,支持声称,前检索过程的影响取决于他们的时间发作。总之,研究结果表明,使用控制过程,以促进成功检索的效率与年龄有关的变化,同时强调发病潜伏期在介导这些变化的作用。
The retrieval of information from episodic memory involves the engagement of pre-retrieval control processes that facilitate the recovery of task-relevant information. The development of these processes was investigated here by comparing neural correlates of retrieval orientation between 13–14-year-old adolescents and young adults. In each age group, event-related potentials (ERPs) elicited by new test pictures were contrasted across two recognition memory tasks (specific vs. general retrieval tasks), which were designed to place greater demands on the recovery of perceptual information associated with each picture in the specific than in the general task. Memory accuracy was higher in the general than in the specific task but did not differ between age groups. In adults, new item ERPs at anterior sites were more positive going in the specific than in the general task from 400 to 1200 ms. In adolescents, the onset latency of this effect was delayed by 300 ms relative to adults, even though no age differences in response speed were obtained in either task. The magnitude of the ERP new item effect in adults correlated with response accuracy, consistent with the view that pre-retrieval processes facilitate the recovery of task-relevant information. For adolescents, this relationship was only obtained for a subset of participants with early onsetting ERP effects, supporting the claim that the influence of pre-retrieval processes depends upon their temporal onset. Together, the findings suggest age-related changes in the efficiency of using control processes to facilitate successful retrieval while highlighting the role of onset latency in mediating these changes.
