Abstract

We examined the auditory sentence processing of neurologically unimpaired listeners and individuals with aphasia on canonical sentence structures in real-time using a visual-world eye-tracking paradigm. The canonical sentence constructions contained multiple noun phrases and an unaccusative verb, the latter of which formed a long-distance dependency link between the unaccusative verb and its single argument (which was base generated in the object position and then displaced to the subject position). To explore the likelihood of similarity-based interference during the real time linking of the verb and the sentence's subject noun, we manipulated the animacy feature of the noun phrases (matched or mismatched). The study's objectives were to examine whether (a) reducing the similarity-based interference by mismatching animacy features would modulate the encoding and retrieval dynamics of noun phrases in real-time; and (b) whether individuals with aphasia would demonstrate on time sensitivity to this lexical-semantic cue. Results revealed a significant effect of this manipulation in individuals both with and without aphasia. In other words, the mismatch in the representational features of the noun phrases increased the distinctiveness of the unaccusative verb's subject target at the time of syntactic retrieval (verb offset) for individuals in both groups. Moreover, individuals with aphasia were shown to be sensitive to the lexical-semantic cue, even though they appeared to process it slower than unimpaired listeners. This study extends to the cue-based retrieval model by providing new insight on the real-time mechanisms underpinning sentence comprehension.

利用词汇语义线索减轻失语症实时语句处理中的干扰效应
本研究采用视觉世界眼动追踪范式,实时观察了神经功能正常的听者和失语症患者对典型句子结构的听觉句子加工。规范句式结构包含多个名词短语和一个非宾格动词,后者在非宾格动词和它的单个实格之间形成了一个远距离的依赖联系(实格在宾语位置产生,然后移到主语位置)。为了探究动词和句子主名词在实时连接过程中出现相似度干扰的可能性,我们对名词短语(匹配或不匹配)的动画特征进行了处理。本研究的目的是探讨(a)减少由不匹配的动画特征引起的相似性干扰是否会实时调节名词短语的编码和检索动态;(b)失语症患者是否表现出对这种词汇语义线索的时间敏感性。结果显示,这种操作对失语症患者和非失语症患者都有显著影响。换句话说,名词短语表征特征的不匹配增加了两组个体在句法检索(动词偏移)时非宾格动词主语目标的独特性。此外,失语症患者被证明对词汇语义线索很敏感,尽管他们的处理速度似乎比未受损的听者慢。该研究扩展到基于线索的检索模型,为句子理解的实时机制提供了新的见解。

期刊介绍: The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
