摘要： 概念启动与熟悉性的研究是近年来内隐记忆与外显记忆神经机制研究的焦点领域之一。双加工理论支持者认为额区300~500 ms (FN400)新旧效应指示熟悉性。单加工理论支持者认为,双加工理论支持者在得出FN400效应指示熟悉性的结论时,没有考虑内隐记忆尤其是概念启动对外显记忆的污染。通过一系列分离熟悉性和概念启动的研究, Paller等人证明了FN400效应指示的是概念启动而不是熟悉性, 并且, 熟悉性由顶区500~800 ms (LPC)新旧效应来指示。目前, 关于FN400效应反映了何种记忆加工仍然存在争议, 未来研究需要探索分离熟悉性和概念启动的新方法, 并进一步考察流畅性对熟悉性影响的神经机制。

Abstract: Conceptual priming and familiarity are hot spots of researches on neuro-mechanisms of implicit and explicit memory. Supporters of dual-process theories put forward that brain potentials at pre-frontal areas between 300 and 500ms (FN400) are associated with familiarity. However, supporters of single- process theories think that studies supporting FN400 as index of familiarity did not take into account the contamination of conceptual priming on explicit memory. Through a series of studies, Paller and his colleagues proved that FN400 is associated with conceptual priming but not familiarity and that familiarity is indexed by brain potentials at parietal areas between 500 and 800ms (LPC). So far, there are still debates on the nero-mechanism of familiarity and conceptual priming. Further researches should explore new methods to dissociate familiarity and conceptual priming. The neuro-mechanism of effects of fluency on familiarity should also be investigated.

Key words: familiarity, conceptual priming, FN400
