There remain few available tools to assess language development in Spanish-English dual language learner (DLL) toddlers in the United States. Of interest is the development of early sentences as children move from producing single words to producing multiword utterances. This study is the first to extend sentence diversity to the context of Spanish-English DLLs by describing development from 24 to 30 months of age in children with and without language delays (LDs).
Spontaneous language samples were collected from Spanish-dominant DLL children and their mothers as they were observed during a free-play interaction. Existing sentence diversity protocols were adapted for the DLL context to describe children's flexibility in combining subjects and verbs to form utterances in Spanish and English.
Children maintained an accurate separation in their grammars for subject-verb combinations in Spanish versus English. There was an overwhelming preference for Spanish subject-verb combinations with null subjects. The emergence of sentence diversity distinguished children with and without early LD unlike the emergence of word combinations.
Consistent with prior research, findings showed that DLLs did not confuse grammatical structures across languages. Instead, they showed a differential pattern of results in each language, such that the strongest grammatical skills were evinced first in the dominant language. Sentence diversity shows promise for assessment and progress monitoring in Spanish-English DLLs in the United States.
在美国,用于评估西班牙语-英语双语学习者(DLL)幼儿语言发展的工具寥寥无几。有趣的是,当儿童从使用单个单词过渡到使用多词表达时,早期句子的发展情况。本研究首次通过描述 24 至 30 个月大的有和无语言延迟(LD)儿童的发展情况,将句子多样性扩展到西班牙语-英语 DLL 背景下。
从西班牙语占主导地位的 DLL 儿童及其母亲那里收集了自然语言样本,这些儿童在自由玩耍互动期间被观察。现有的句子多样性协议被改编为 DLL 环境,以描述儿童在西班牙语和英语中灵活地组合主语和动词以形成话语的能力。
儿童在西班牙语和英语中对主语-动词组合的语法保持了准确的区分。对具有零主语的西班牙语主语-动词组合有着压倒性的偏好。句子多样性的出现区分了有和无早期 LD 的儿童,而不是词组合的出现。
与先前的研究一致,研究结果表明,DLL 并没有混淆跨语言的语法结构。相反,他们在每种语言中表现出不同的结果模式,即首先在主导语言中表现出最强的语法技能。句子多样性在美国的西班牙语-英语 DLL 评估和进展监测中具有很大的应用前景。
