Language is a core cognitive faculty. Research on language processing is typically carried out independently of research within other cognitive domains. However, it has been proposed that language shares basic sensorimotor features with non-linguistic cognition at the representational level. The present paper investigates whether processing principles are also shared between linguistic and non-linguistic cognition; specifically, it is investigated whether the N400 is sensitive to global and local manipulations of violation probability as previously reported for markers of non-linguistic conflict detection. In Experiment 1, the global violation probability was manipulated. Here, N400 amplitude was reduced in high violation probability blocks compared to low violation probability blocks. In Experiment 2, N400 amplitude was analysed according to local trial sequence. Here, the N400 amplitude difference between correct and violated sentences was reduced when the preceding trial was a violation compared to a correct trial. The implication of these findings for the architecture of our cognitive system is discussed.
语言是一种核心认知能力。对语言处理的研究通常独立于其他认知领域的研究进行。然而，有人提出，在表征层面上，语言与非语言认知共享基本的感觉运动特征。本文研究语言认知和非语言认知之间是否也共享处理原则；具体而言，研究N400是否像先前报道的非语言冲突检测标记那样，对违反概率的全局和局部操纵敏感。在实验1中，操纵了全局违反概率。在此，与低违反概率块相比，高违反概率块中的N400波幅降低。在实验2中，根据局部试验序列分析N400波幅。在此，与正确试验相比，当先前试验为违反时，正确句子和违反句子之间的N400波幅差异减小。讨论了这些发现对我们认知系统结构的意义。
