将印刷与意义联系起来往往分为子过程，如识别输入的词条和随后的语义获取。然而，最近的结果表明，由输入激活的一组语义特征比一种观点所暗示的更广泛，在这种观点中，访问是在识别之后顺序进行的。脑电是从参与者那里收集的，这些参与者观看的项目在拼写邻居和词汇联想的数量和频率上都不同。对单项事件相关电位的回归分析重复了过去的研究结果，结果表明，相邻项越多，N400波幅越大，并进一步表明，具有更多词汇关联性和更高频率的邻项或关联项的项，N400波幅也会增加。综上所述，这些数据表明，在N400时间窗口中，与输入广泛相关的项目的语义特征是活跃的，这与语义获取与刺激识别平行进行的模型一致。
Linking print with meaning tends to be divided into subprocesses, such as recognition of an input's lexical entry and subsequent access of semantics. However, recent results suggest that the set of semantic features activated by an input is broader than implied by a view wherein access serially follows recognition. EEG was collected from participants who viewed items varying in number and frequency of both orthographic neighbors and lexical associates. Regression analysis of single item ERPs replicated past findings, showing that N400 amplitudes are greater for items with more neighbors, and further revealed that N400 amplitudes increase for items with more lexical associates and with higher frequency neighbors or associates. Together, the data suggest that in the N400 time window semantic features of items broadly related to inputs are active, consistent with models in which semantic access takes place in parallel with stimulus recognition.
