事件相关电位（ERP）的N400分量是在Neely [J.H. Neely，语义启动和词汇记忆的提取：无抑制扩散激活和有限容量注意的作用，实验心理学杂志：总论，第106卷（1977），pp. 226-254.]范式，允许无混淆的语义启动效应：由于自动和注意过程。结果发现，启动和目标之间250 ms的短刺激起始延迟（SOA）与N400振幅的自动而非预期效应相关。在启动和目标之间的长SOA为2000 ms时，N400的语义启动效应与自动和期望过程相关。此外，在两个SOA的自动效应的幅度没有显着差异，这表明自动处理没有衰减在2000毫秒的间隔之间的启动和目标。这一结果支持了Posner和Synder提出的语义启动的双加工解释。波斯纳C.R.R.

The N400 component of event-related potentials (ERPs) was obtained in a modified version of the Neely [J.H. Neely, Semantic priming and retrieval from lexical memory: Roles of inhibitionless spreading activation and limited-capacity attention, Journal of Experimental Psychology: General, Vol. 106 (1977), pp. 226-254.] paradigm which permits unconfounding of semantic priming effects: due to automatic and attentional processes. It was found that a short stimulus onset asynchrony (SOA) of 250 ms between the prime and the target was associated with automatic but not expectancy effects on the amplitude of N400. At a long SOA of 2000 ms between prime and target, semantic priming effects on N400 were obtained associated with both automatic and expectancy processes. Moreover, there was no significance difference in the magnitude of the automatic effects at the two SOAs, suggesting that automatic processing had not decayed within the 2000 ms interval between the prime and target. The results support the two-processing interpretation of semantic priming advanced by Posner and Synder [M.I. Posner, C.R.R. Snyder, Attention and cognitive control, in: R.L. Solso (Ed.), Information Processing and Cognition: The Loyola Symposium, Erlbaum, Hillsdale, NJ (1975).] and concur with the results of Neely [J.H. Neely,. Semantic priming and retrieval from lexical memory: Roles of inhibitionless spreading activation and limited-capacity attention, Journal of Experimental Psychology: General, Vol. 106 (1977), pp. 226-254], with the exception of indicating a longer persistence of automatic processes.
