在识别记忆排除任务的测试阶段中获得了与事件相关的电位（ERP），以便有助于当前对负责对内存检索进行战略控制方式的过程的理解。要求参与者从一个研究任务（目标）中认可旧单词，并拒绝新的测试词以及第二个研究任务（非目标）中的旧单词。指定为目标类别的研究任务在测试阶段各不相同。左边的ERP旧/新效应 - 回忆的电生理标志 - 仅在所有测试阶段的目标上可靠，这与参与者的观点一致，即参与者在策略性地控制任务需求。根据目标名称分开的新测试词引起的ERP之间的对比显示了中线，前和右脊椎位置的可靠差异。这些差异可能反映了构成检索尝试的一部分的过程，并在此解释为对情节检索的战略调节很重要的过程索引。 （c）2004 Elsevier Ltd.保留所有权利。
Event-related potentials (ERPs) were acquired during test phases of a recognition memory exclusion task, in order to contribute to current understanding of the processes responsible for the ways in which memory retrieval can be controlled strategically. Participants were asked to endorse old words from one study task (targets) and to reject new test words as well as those from a second study task (non-targets). The study task designated as the target category varied across test phases. The left-parietal ERP old/new effect - the electrophysiological signature of recollection - was reliable for targets only in all test phases, consistent with the view that participants control recollection strategically in service of task demands. The contrast between the ERPs evoked by new test words separated according to target designation revealed reliable differences at midline, anterior and right-hemisphere locations. These differences likely reflect processes that form part of a retrieval attempt and are interpreted here as indices of processes that are important for the strategic regulation of episodic retrieval.
