该研究利用事件相关电位技术（ERPs），采用以汉字为实验材料的学习-再认范式，考察了语义相似性下回忆和熟悉性的分离。本实验结果表明：熟悉性效应主要体现在330-430ms的额区，而回忆效应主要体现在430-600ms的中央区和顶区。本实验在以汉字为实验材料的情况下证明了，早期额区的N400新旧效应反映了熟悉性，晚期顶区LPC新旧效应反映了回忆，从汉语材料的角度，为双加工过程假说提供了新的证据。

The study adopted a “study-test” pattern and the materials of Chinese characters to explore the dissociation of recollection from familiarity in condition of conceptual-similarity using event-related potential (ERPs) measurements. The results showed that the familiarity effect was mainly reflected in the region of frontal during 330-430ms. The recollection effect was mainly reflected in the region of central and parietal during 430-600ms. In the case of Chinese characters, the study confirmed that the earlier N400 old\new effects reflected familiarity and the later parietal LPC reflected recollection. The study provided a new evidence for the hypothesis of dual-process from the Chinese material viewpoint.
