本实验探讨了语义期望对语法性别加工的影响。反之亦然，在德语中使用事件相关电位（ERP）。向受试者提供正确的句子和包含违反冠词-名词性别协议的句子。名词打瞌睡的概率有高有低。 ERP 是根据名词来测量的。低完形填空名词比高完形填空名词引起更大的 N400。性别违规导致 ail 名词出现左前否定（LAN，300-600 毫秒）。仅在高完形填空名词中发现了额外的 P600 成分。 N400 与性别不匹配变量无关； LAN 独立于语义变量，而在 P600 中发现了两个变量的相互作用。这一发现表明句法和语义过程在早期处理阶段是自主的，而这些信息类型在后期处理阶段相互作用。
This experiment explored the effect of semantic expectancy on the processing of grammatical gender. and tice versa, in German using event-related-potentials (ERPs). Subjects were presented with correct sentences and sentences containing an article-noun gender agreement violation. The doze probability of the nouns was either high or low. ERPs were measured on the nouns. The low-cloze nouns evoked a larger N400 than the high-cloze nouns. Gender violations elicited a left-anterior negativity (LAN, 300-600 msec) for ail nouns. An additional P600 component was found only in high-cloze nouns. The N400 was independent of the gender mismatch variable; the LAN was independent of the semantic variable, whereas an interaction of the two variables was found in the P600. This finding indicates that syntactic and semantic processes are autonomous during an early processing stage, whereas these information types interact during a later processing phase.
