This study investigated the phonetic processing of new words in 3-to-8-year-old children with Williams syndrome (WS). Word-learning abilities were evaluated with a task involving the learning of two phonetically similar words for two different objects. Overall, children with WS were able to process fine phonetic details while establishing new word-object links. Their performance pattern was predicted by their mental age and was characterized by an asymmetrical processing of consonant and vowel information to the advantage of consonants found with this task in younger, typically developing, children. These results show delayed but relatively preserved word-learning abilities in WS, and this trajectory is discussed in comparison with typical development.
本研究调查了患有威廉姆斯综合征（WS）的3至8岁儿童对新单词的语音处理能力。通过一项任务评估单词学习能力，该任务涉及为两个不同物体学习两个语音相似的单词。总体而言，患有WS的儿童在建立新的单词与物体联系时能够处理精细的语音细节。他们的表现模式由其心理年龄预测，其特点是对辅音和元音信息的不对称处理，这有利于在年龄较小、发育正常的儿童完成此任务时发现的辅音。这些结果表明，WS儿童的单词学习能力虽有延迟但相对保留，并且将这一发展轨迹与正常发育进行了比较讨论。
