利用事件相关脑电位（ERP）的神经语言学研究通常将句法短语结构处理与大约150至200毫秒的早期自动处理阶段相关联，而形态句法处理与300至500毫秒之间的后期和更依赖注意力的处理阶段相关联。然而，最近的研究已经挑战了这一立场，报告高度自动ERP影响morphosyntax在100至200毫秒的时间范围内。本研究旨在确定可能导致潜伏期和自动性变化的因素。在两个实验中不同程度的注意，德国短语结构和morphosyntax违规进行了比较的条件下，违反句法关系的地方，以及违反点和语音刺激的声学特性，严格控制。一个负性100和300毫秒之间的违规点发生后，在这两种类型的句法违规和独立的注意力资源的分配。这些研究结果表明，时间和自动性的ERP效果反映特定的句法子过程的影响，在更大程度上的方法比语言因素，因此，需要被视为相对的，而不是固定的时间连续的处理阶段。
Neurolinguistic research utilizing event-related brain potentials (ERPs) typically relates syntactic phrase structure processing to an early automatic processing stage around 150 to 200 msec, whereas morphosyntactic processing is associated with a later and somewhat more attention-dependent processing stage between 300 and 500 msec. However, recent studies have challenged this position by reporting highly automatic ERP effects for morphosyntax in the 100 to 200 msec time range. The present study aimed at determining the factors that could contribute to such shifts in latency and automaticity. In two experiments varying the degree of attention, German phrase structure and morphosyntactic violations were compared in conditions in which the locality of the violated syntactic relation, as well as the violation point and the acoustic properties of the speech stimuli, were strictly controlled for. A negativity between 100 and 300 msec after the violation point occurred in response to both types of syntactic violations and independently of the allocation of attentional resources. These findings suggest that the timing and automaticity of ERP effects reflecting specific syntactic sub-processes are influenced to a larger degree by methodological than by linguistic factors, and thus, need to be regarded as relative rather than fixed to temporally successive processing stages.
