基于最近的研究结果显示，成年语言学习者的电生理变化后，相对较短的时间内的培训，我们假设，成年荷兰学习者的德语将显示德国的性别和形容词变格侵犯简短的指令后的反应。德语中的形容词变格与先前研究的形态句法变格不同，因为所需的后缀不仅取决于要表达的句法格、性和数特征，而且还取决于这些特征是否已经表达在名词短语中的线性前置元素上。违规短语和匹配的控制，提出了三个测试阶段（前测和培训的第一天，一周后的后测）。在预测试中，违反和控制条件之间没有观察到电生理差异，参与者的分类性能接近机会。在训练和后测阶段，分类改善，并有一个P600样的违规反应变格，但没有性别侵犯。在培训过程中的错误相关的反应与改进的语法歧视从前测到后测。结果表明，在一个复杂的形态句法规则的成年学习者中，可以观察到神经元反应的快速变化，并且错误相关的电生理反应可能与语法习得有关。
Based on recent findings showing electrophysiological changes in adult language learners after relatively short periods of training, we hypothesized that adult Dutch learners of German would show responses to German gender and adjective declension violations after brief instruction. Adjective declension in German differs from previously studied morphosyntactic regularities in that the required suffixes depend not only on the syntactic case, gender, and number features to be expressed, but also on whether or not these features are already expressed on linearly preceding elements in the noun phrase. Violation phrases and matched controls were presented over three test phases ( pretest and training on the first day, and a posttest one week later). During the pretest, no electrophysiological differences were observed between violation and control conditions, and participants' classification performance was near chance. During the training and posttest phases, classification improved, and there was a P600-like violation response to declension but not gender violations. An error-related response during training was associated with improvement in grammatical discrimination from pretest to posttest. The results show that rapid changes in neuronal responses can be observed in adult learners of a complex morphosyntactic rule, and also that error-related electrophysiological responses may relate to grammar acquisition.
