The present study investigates the processes involved in the recovery from temporarily ambiguous garden-path sentences. Event-related brain potentials (ERP) were recorded while subjects read German subject-object ambiguous relative and complement clauses. As both clause types are initially analyzed as subject-first structures, object-first structures require a revision which is more difficult for complement than for relative clauses. The hypothesis is tested that the revision process consists of two sub-processes, namely diagnosis and actual reanalysis. Applying a spatio-temporal principal component analysis to the ERP data, distinct positive sub-components presumably reflecting different sub-processes could be identified in the time range of the P300 and P600. It will be argued that the P600 is not a monolithic component, and that different sub-processes may be involved at varying time points depending on the type of garden-path sentence.
本研究调查了从暂时歧义的花园小径句子中恢复的过程。在受试者阅读德语主宾歧义关系从句和补语从句时，记录了事件相关脑电位（ERP）。由于这两种从句类型最初都被分析为主语在前的结构，宾语在前的结构需要修正，而补语从句比关系从句更难修正。本研究检验了这样一个假设，即修正过程由两个子过程组成，即诊断和实际重新分析。对ERP数据应用时空主成分分析，可以在P300和P600的时间范围内识别出可能反映不同子过程的明显正性子成分。有人认为，P600不是一个单一的成分，并且根据花园小径句子的类型，不同的子过程可能在不同的时间点涉及。
