This paper describes an experiment which shows that roughly half of nondemented patients with Parkinson's disease (PD) have impaired comprehension of subject-to-subject and object-to-subject raising constructions (e.g., Susan seems to Bill to be tall and Susan is hard for Bill to catch), but have normal comprehension of the counterpart constructions (e.g., It seems to Bill that Susan is tall and It's hard for Bill to catch Susan). Several possible explanations for this pattern of performance are considered, including a parsing disorder, a syntactic-semantic linking disorder, a reduction of working memory capacity, slowed speed of syntactic processing, and difficulty with the experimental task. Although some of these explanations are arguably more plausible than others, the exact nature of the comprehension impairment remains unclear.
本文描述了一项实验，该实验表明，大约一半的非痴呆帕金森病（PD）患者对主语到主语和宾语到主语提升结构（例如，苏珊对比尔来说似乎很高，苏珊对比尔来说很难抓住）的理解受损，但对相应结构（例如，对比尔来说，苏珊似乎很高，比尔很难抓住苏珊）的理解正常。文中考虑了几种对这种表现模式的可能解释，包括句法分析障碍、句法-语义连接障碍、工作记忆容量降低、句法处理速度减慢以及实验任务难度。尽管其中一些解释可能比其他解释更合理，但理解障碍的确切性质仍不清楚。
