ERPs由两种类型的拼写法律的，发音非词引起。一个非词集是从真实的词衍生出来的，与之相似，而另一个则不是。非词来自相关的根词引起的N400语义启动效应类似的单词，表示根词的语义激活。N400重复启动效应nonderived非词获得的单词。N400仅由派生的非词引出，这表明它是由词义激活产生的。然而，这两种类型的非词产生了N400和N400启动效应。由于非派生非词与意义无关，N400不能由语义激活本身产生。相反，N400似乎是由正字法/语音分析产生的，并通过自上而下的语义信息到正字法/语音水平的反馈而衰减。
ERPs were elicited by two types of orthographically legal, pronounceable nonwords. One nonword set was derived from and resembled real words, whereas the other set did not. Nonwords derived from related root words elicited N400 semantic priming effects similar to those obtained for words, indicating semantic activation of the root words. N400 repetition priming effects from nonderived nonwords were similar to those obtained for words. The elicitation of N400 by only derived nonwords would have suggested it was generated by the activation of word meanings, per se. However, both types of nonwords produced an N400, and an N400 priming effect. Because nonderived nonwords are not associated with meaning, the N400 cannot be generated by semantic activation per se. Rather, the N400 appears to be generated by orthographic/phonological analysis and is attenuated by the top-down feed of semantic information to the orthographic/phonological level.
