二个事件相关的潜在的实验被进行调查时间并且为条款识别任务和分别地把图画和汉字用作刺激的听觉的来源检索任务的旧 / 新的效果的空间分布。刺激在屏幕的中心上被介绍，他们的名字在学习阶段期间同时由女性或由男声音读出然后二测试独立被执行。测试任务是把旧项目区分开来与新的，和另外的任务是判定某个声音作为非目标作为目标和另一个在学习阶段期间读出的项目。结果证明听觉的来源检索任务的旧 / 新的效果是在实验，和以前的效果的空间分发比条款识别任务的随着时间的过去支撑的更多比后者的宽一个。两个实验在来源检索任务期间在前额的外皮上记录了可靠旧 / 新的效果。然而，在那里存在为在图画和汉字之间的听觉的来源检索任务的旧 / 新的效果的一些差别，和 LORETA 来源分析显示差别可能根植于时间的脑叶。这些调查结果证明在条款识别任务和听觉的来源检索任务之间的旧 / 新的效果的关联支持双过程的模型；空间并且听觉的来源检索任务得到的旧 / 新的效果的时间的分布被两个调整试验性的材料的特征和声音的感性的属性。

英文摘要：

Two event-related potential experiments were conducted to investigate the temporal and the spatial distributions of the old/new effects for the item recognition task and the auditory source retrieval task using picture and Chinese character as stimuli respectively. Stimuli were presented on the center of the screen with their names read out either by female or by male voice simultaneously during the study phase and then two testa were performed separately. One test task was to differentiate the old items from the new ones, and the other task was to judge the items read out by a certain voice during the study phase as targets and other ones as non-targets. The results showed that the old/new effect of the auditory source retrieval task was more sustained over time than that of the item recognition task in both experiments, and the spatial distribution of the former effect was wider than that of the latter one. Both experiments recorded reliable old/new effect over the prefrontal cortex during the source retrieval task. However, there existed some differences of the old/new effect for the auditory source retrieval task between picture and Chinese character, and LORETA source analysis indicated that the differences might be rooted in the temporal lobe. These findings demonstrate that the relevancy of the old/new effects between the item recognition task and the auditory source retrieval task supports the dual-process model; the spatial and the temporal distributions of the old/new effect elicited by the auditory source retrieval task are regulated by both the feature of the experimental material and the perceptual attribute of the voice.
