Syntactic priming is the facilitation of processing that occurs when a sentence has the same syntactic form as a preceding sentence. Such priming effects have been less consistently demonstrated in comprehension than in production, and those that have been reported have depended on the repetition of verbs across sentences. In an event-related potential experiment, subjects read target sentences containing reduced-relative clauses. Each was preceded by a sentence that contained the same verb and either a reduced-relative or a main-clause construction. Reduced-relative primes elicited a larger positivity than did main-clause primes. Reduced-relative targets that were preceded by a main-clause prime elicited a greater positivity than the same target sentences following a reduced-relative prime. In addition, syntactic priming effects were dissociated from effects of lexical repetition at the verb.
句法启动是指当一个句子与前一个句子具有相同的句法形式时所发生的加工促进作用。与产出相比,这种启动效应在理解中得到的证明不太一致,而且所报告的那些效应依赖于跨句子的动词重复。在一项事件相关电位实验中,受试者阅读包含简化关系从句的目标句子。每个目标句子之前都有一个包含相同动词以及简化关系从句或主句结构的句子。简化关系从句启动句比主句启动句引发了更大的正向波。由主句启动句引导的简化关系从句目标比由简化关系从句启动句引导的相同目标句子引发了更大的正向波。此外,句法启动效应与动词处的词汇重复效应是分离的。
