我们调查威廉姆斯综合症 (WS) 患者的核心句法和语义原则知识。我们的研究重点是否定和析取(or)的逻辑句法属性,并测试(a)核心句法关系(范围和c-命令),(b)核心语义关系(蕴含关系和命题逻辑的德摩根定律)以及(c)(a)和(b)之间的关系的知识。我们检查了 WS 患者、与心理年龄 (MA) 相匹配的儿童以及典型的以英语为母语的成人的表现。所有条件下的表现表明所有三组都存在并参与了 (a-c) 的知识。结果还表明,与 MA 相比,WS 组 (c) 的表现略有下降,这与处理资源的限制一致。讨论了这些结果对 WS 中语言发展的竞争性解释的影响,以及 WS 与认知结构和发展研究的相关性。
We investigate knowledge of core syntactic and semantic principles in individuals with Williams Syndrome (WS). Our study focuses on the logico-syntactic properties of negation and disjunction (or) and tests knowledge of (a) core syntactic relations (scope and c-command), (b) core semantic relations (entailment relations and DeMorgan's laws of propositional logic), and (c) the relationship between (a) and (b). We examine the performance of individuals with WS, children matched for mental age (MA), and typical adult native speakers of English. Performance on all conditions suggests that knowledge of (a-c) is present and engaged in all three groups. Results also indicate slightly depressed performance on (c) for the WS group, compared to MA, consistent with limitation in processing resources. Implications of these results for competing accounts of language development in WS, as well as for the relevance of WS to the study of cognitive architecture and development are discussed.
