采用事件相关电位（ERP）方法，比较了大学生汉语名词项目再认和位置来源提取的头皮时空分布。学习屏幕左侧（或右侧）呈现名词后在屏幕中央呈现新、旧名词，对受试者进行两类测验：其一是判断名词是否已学过；其二是将从某侧学得的名词判断为目标，而将其他名词判断为非目标的来源测验。结果发现：（1）汉字位置来源提取与项目再认新／旧效应的持续时程相同，但前者较后者在600～1000ms的头皮分布更广，该结果支持描述项目记忆与来源记忆关系的双重加工模型，且两种记忆的新／旧效应并非总以序列方式发生；（2）汉字与前人西文单词、图形的位置来源提取效应的头皮分布相似，都集中于前额区，表明来源特性对来源信息提取具有调节作用；（3）非目标-旧名词与目标名词新／旧效应的头皮分布特征不同，表明来源信息提取受任务定向影响。
採用事件相關電位（ERP）方法，比較瞭大學生漢語名詞項目再認和位置來源提取的頭皮時空分佈。學習屏幕左側（或右側）呈現名詞後在屏幕中央呈現新、舊名詞，對受試者進行兩類測驗：其一是判斷名詞是否已學過；其二是將從某側學得的名詞判斷為目標，而將其他名詞判斷為非目標的來源測驗。結果髮現：（1）漢字位置來源提取與項目再認新／舊效應的持續時程相同，但前者較後者在600～1000ms的頭皮分佈更廣，該結果支持描述項目記憶與來源記憶關繫的雙重加工模型，且兩種記憶的新／舊效應併非總以序列方式髮生；（2）漢字與前人西文單詞、圖形的位置來源提取效應的頭皮分佈相似，都集中于前額區，錶明來源特性對來源信息提取具有調節作用；（3）非目標-舊名詞與目標名詞新／舊效應的頭皮分佈特徵不同，錶明來源信息提取受任務定嚮影響。

An event-related potentials study was conducted to compare the temporal and spatial distributions of the old/new effects in item recognition and location source retrieval for Chinese nouns with undergraduates as participants. Chinese nouns were presented either on the left or on the fight screen, and then two tests were performed with old and new nouns presented on the central screen. The first task was to decide whether each noun had been learned or not, and the second task was to judge nouns learned from one location as targets and the other nouns as non-targets. The results indicated that： （ 1 ） The spatial distribution of the old/new effect for location source retrieval was wider than that of item memoryfor Chinese nouns during 600 - 1000ms, which supported the dual-process model. And the lasting duration of these two effects was same, which demonstrated source retrieval and item recognition didn＇t always occur hierarchically. （2） The spatial distribution of location source retrieval effect for Chinese nouns was concentrated on prefrontal cortex similar to that for pictures and foreign words in previous studies, which suggested the characteristic of source was an important factor affecting source retr/eval. （3） The spatial distributive characteristics of the old/new effects target and nontarget-old nouns were different,which indicated task orientation also affected source retr/eval.
