本研究考察了两名语法性失语者的“复合句”的产生,其中包括名词短语的移动。根据语言学理论(乔姆斯基,1991年,1993年),这样的句子是使用两个移动操作之一,无论是wh-或NP-移动,归入一般规则“移动阿尔法。“在这个实验中,使用治疗研究范式对wh-和NP-运动衍生句子的恢复进行了研究。受试者被顺序地训练以产生eitherwh-movement(即,whoquestions,object clefts)或NP-移动(即,被动句、主语提升结构)派生句。在整个训练过程中,对依赖于这两种类型的运动的未训练句子的泛化进行了测试。训练对叙事语篇各方面的影响也进行了研究。结果表明,泛化模式限制的运动类型:Trainingwh-movement结构导致untrainedwh-movement结构的广义生产,而不影响生产的NP-运动结构。同样,NP移位结构的训练只导致了对同样依赖于NP移位的其他句子类型的泛化。在叙述性语境中的句子产生方面也得到了改善。这些数据表明,在NP-移动中,移动到一个论元(A)位置不同于移动到一个非论元(A-杠)位置,这是在wh-movement中所需要的。非规范句的s-结构中运动终止的位置似乎会影响句子的产生。这些研究结果表明,句子的语言特性影响失语症的句子产生故障和恢复。
The present research examines production of "complex" sentences, which involve movement of noun phrases (NPs), in 2 agrammatic aphasic subjects. According to linguistic theory (Chomsky, 1991, 1993), such sentences are derived using one of two movement operations, eitherwh- or NP-movement, subsumed under the general rule "move alpha." In this experiment recovery of bothwh- and NP-movement derived sentences was investigated using a treatment research paradigm. Subjects were sequentially trained to produce eitherwh-movement (i.e.,whoquestions, object clefts) or NP-movement (i.e., passives, subject-raising structures) derived sentences. Throughout training, generalization to untrained sentences relying on both types of movement was tested. The influence of training on aspects of narrative discourse also was examined. Results showed generalization patterns constrained to type of movement: Trainingwh-movement structures resulted in generalized production of untrainedwh-movement structures without influencing production of NP-movement structures. Similarly, training of NP-movement structures resulted in generalization only to other sentence types also relying on NP-movement. Aspects of sentence production in narrative contexts also was improved with treatment. These data indicate that movement to an argument (A) position as in NP-movement is distinct from movement to a nonargument (A-bar) position, required inwh-movement. The site where movement terminates in the s-structure of noncanonical sentences appears to influence sentence production. These findings show that linguistic properties of sentences influence sentence production breakdown and recovery in aphasia.
