Abstract
This study examined the scope of lexical planning in second language (L2) production using the semantic blocking effect and its associated patterns of ERPs. The semantic blocking effects—as measured by longer response times in picture naming tasks and often interpreted as a reflection of difficulty in lexical access—have been observed when all objects of a set belong to an identical semantic category than diverse categories. Two experiments were conducted to observe patterns of ERPs associated with the semantic blocking effects (i.e., semantic context effects) by using two types of subject nounphrases that include two nouns, a head noun modified by a prepositional phrase (PP) (e.g., the dog above the flower is red) and a conjoined noun phrase (CNP) (e.g., the dog and the flower are both red). The first noun (homogeneous vs. heterogeneous) in the set of pictures was manipulated in Experiment 1, and the second noun in Experiment 2. The ERP results showed that semantic blocking effects were observed in both experiments, in contrast to previous findings for native speaker production, providing no evidence for incremental planning in L2 sentence production. Instead, different ERP patterns were found for the subject NP type (PP vs. CNP) in both experiments, showing that the lexical planning scope in L2 sentence production might vary according to functional phrases—i.e., the relation between two NPs composing the subject noun-phrases.
本研究利用erp的语义阻断效应及其相关模式考察了二语词汇规划的范围。当一个集合中的所有对象属于相同的语义类别而不是不同的类别时,可以观察到语义阻塞效应——通过在图片命名任务中更长的响应时间来衡量,并且通常被解释为词汇访问困难的反映。通过两种类型的主语短语,包括两个名词,一个由介词短语修饰的头名词(PP)(例如,花上面的狗是红色的)和一个连体名词短语(CNP)(例如,狗和花都是红色的),进行了两个实验,以观察与语义阻塞效应(即语义语境效应)相关的erp模式。实验1对图片组中的第一个名词(同质或异质)进行处理,实验2对第二个名词进行处理。ERP结果显示,在这两个实验中都观察到语义阻塞效应,这与先前的研究结果相反,没有证据表明增量计划在二语句子生成中存在。相反,在两个实验中,受试者NP类型(PP vs. CNP)的ERP模式不同,这表明二语句子生成中的词汇规划范围可能因功能短语而异。构成主语名词短语的两个np之间的关系。
