本文介绍了一个句法加工实验的事件相关脑电位(ERP)数据。受试者阅读包含三种不同类型的违反荷兰语句法限制之一的句子。ERP结果为句法加工的电生理反应提供了证据，这种电生理反应与已建立的语义加工的ERP反应有质的不同。我们将这种分析的电生理表现称为句法正移(SPS)。在一个实验中，除了阅读输入外，没有对被试施加任何任务要求。对不同种类的句法违规的响应模式表明，SPS指示解析器不可能将优选结构分配给输入的单词串，而不管该优选结构的特定句法性质。本文还讨论了这些发现对进一步句法分析研究的启示。
This paper presents event-related brain potential (ERP) data from an experiment on syntactic processing. Subjects read individual sentences containing one of three different kinds of violations of the syntactic constraints of Dutch. The ERP results provide evidence for an electrophysiological response to syntactic processing that is qualitatively different from established ERP responses to semantic processing. We refer to this electrophysiological manifestation of parsing as the Syntactic Positive Shift (SPS).The SPS was observed in an experiment in which no task demands, other than to read the input, were imposed on the subjects. The pattern of responses to the different kinds of syntactic violations suggests that the SPS indicates the impossibility for the parser to assign the preferred structure to an incoming string of words irrespective of the specific syntactic nature of this preferred structure. The implications of these findings for further research on parsing are discussed.
