Purpose Proficiency with complex syntax is important for language and reading comprehension, and production of complex syntax begins to emerge shortly after a young child begins using two-word combinations. Complex syntax production in preschool children with hearing loss who use spoken language has been explored minimally. The purpose of this study was to compare complex syntax production of 4-year-old children with hearing loss to age-matched and language-matched peers with normal hearing. Method Seventy-two children completed a language assessment battery, including a structured language sample. Complex syntax density and number and accuracy of productions of particular types of complex syntax were compared across three groups: 4-year-old children with hearing loss, an age-matched group of children with normal hearing, and an mean length of utterance (MLU)-matched group of children with normal hearing. Results Children with hearing loss had lower complex syntax density and fewer correct productions of coordinated clauses, subordinate clauses, and simple infinitives than their age-matched, but not language-matched, peers. Furthermore, children with hearing loss had lower accuracy than the age-matched group on simple infinitives and lower accuracy than both the age- and MLU-matched groups on full propositional complements and subject relative clauses. Conclusion Children with hearing loss exhibit delays in complex syntax acquisition as compared to their same-age peers and disruptions in development on some complex structures as compared to MLU-matched, younger children.

复杂句法的熟练程度对于语言和阅读理解都很重要,并且复杂句法的产生始于儿童开始使用双词组合之后不久。对于使用口语的听力损失的学龄前儿童,复杂句法的产生已经得到了初步探索。本研究的目的是比较听力损失的 4 岁儿童与年龄匹配和语言匹配的正常听力儿童的复杂句法产生情况。
72 名儿童完成了语言评估测试,包括语言样本的结构。比较了三组儿童的复杂句法密度和特定类型的复杂句法的生成数量和准确率:听力损失的 4 岁儿童、年龄匹配的正常听力儿童和语言匹配的正常听力儿童。
听力损失儿童的复杂句法密度较低,协调从句、从属从句和简单不定式的正确生成数量少于其年龄匹配的但非语言匹配的同龄儿童。此外,听力损失儿童在简单不定式上的准确率低于年龄匹配组,在完整命题补语和主从关系从句上的准确率低于年龄和语言匹配组。
与同龄儿童相比,听力损失儿童在复杂句法习得方面存在延迟,与语言匹配的年幼儿童相比,他们在某些复杂结构的发展上存在障碍。
