The present study reports a case of dizygotic twins, one boy with Williams syndrome (WS) and one typically developing girl, and compares their neuropsychological profiles. The goal of the present authors was to verify whether the child with WS displayed a cognitive profile which is unique to the syndrome. Several tests designed to assess visuo-perceptual, visuo-motor, linguistic and memory abilities were administered to both children when they were 10.9 years old. Compared to his sister, the boy with WS displayed a homogeneous developmental delay in both non-verbal and verbal abilities. He achieved a level of performance similar to his sister only in facial recognition, phonological word fluency and memory for phonologically similar words. Furthermore, despite the overall delayed performance of the boy, both the twins displayed a cognitive profile characterized by strength in lexical comprehension and relative weakness in visuo-motor abilities.
本研究报告了一例异卵双胞胎病例，其中一个男孩患有威廉姆斯综合征（WS），另一个是发育正常的女孩，并比较了他们的神经心理学特征。本研究作者的目的是验证患有WS的儿童是否表现出该综合征特有的认知特征。当两个孩子10.9岁时，对他们进行了多项旨在评估视觉感知、视觉运动、语言和记忆能力的测试。与他的妹妹相比，患有WS的男孩在非语言和语言能力方面均表现出均匀的发育迟缓。他仅在面部识别、语音单词流畅性和语音相似单词记忆方面达到了与妹妹相似的表现水平。此外，尽管男孩的整体表现有所延迟，但这对双胞胎都表现出一种认知特征，即词汇理解能力较强，视觉运动能力相对较弱。
