本研究的目的是确定是否N400组件，所描述的Kutas和Hillyard作为一个指数的语义预期，将引起的偏差，涉及非语言的期望。四种实验条件下的刺激包括：1）句子，2）大小递增或递减的几何图案，3）频率递增或递减的音阶音符，4）众所周知的法国旋律。N400只出现在句子中语义不一致的情况下。 非语言的偏差，其次是一个晚的积极性，其幅度不同的条件。这些结果是一致的解释N400作为一个指数的进一步处理所需的语言不一致，而不是违反任意或过度学习的规则一般。然而，存在其他解释，并进行了讨论。
This study was designed to determine whether the N400 component, described by Kutas and Hillyard as an index of semantic expectancy, would be elicited by deviations involving non-linguistic expectancies. The stimuli within the four experimental conditions include: 1) sentences, 2) geometric patterns of increasing or decreasing size, 3) scale-notes of increasing or decreasing frequency, and 4) welll-known French melodies. An N400 appeared only following semantic incongruities within sentences. Non-linguistic deviations were followed by a late positivity whose amplitude varied across conditions. These results are consistent with an interpretation of N400 as an index of the further processing required by linguistic incongruities rather than by violations of arbitrary or overlearned rules in general. However, alternative interpretations exist and are discussed.
