生产力和句子组织是量化单语和双语儿童语言发展和语言障碍的有用指标。目前尚不清楚在评估双语儿童的语言技能时，哪些语言内部和跨语言的衡量标准最能提供信息。本研究的目的是评估两种语言的语言生产力和组织的测量如何与儿童在双语英语西班牙语评估（BESA）中测量的语言能力相一致，这是一种标准化的语言能力测量。170名幼儿园年龄的儿童根据一本没有文字的绘本制作了西班牙语和英语的叙事语言样本。分析了样本的话语数量、不同单词的数量、平均话语长度和语法话语的百分比。由BESA分数衡量的语言能力的最佳预测指标是英语MLU，英语语法性和西班牙语语法性。讨论了结果与每一种语言的测量性质的关系，以及它们在识别双语者低语言能力方面的潜在效用。学习成果:读者将能够识别(1)为什么叙事对评估双语语言能力有用；(2)叙事中哪些生产力和句子组织的衡量标准最能反映双语儿童的语言能力和发展；(3)如何确定跨两种语言的双语或复合语言能力；(4)使用双语语言能力评分的每种语言的生产力和句子组织的衡量标准之间存在什么关系。(C) 2010爱思唯尔公司版权所有。
Measures of productivity and sentence organization are useful metrics for quantifying language development and language impairments in monolingual and bilingual children. It is not yet known what measures within and across languages are most informative when evaluating the language skills of bilingual children. The purpose of this study was to evaluate how measures of language productivity and organization in two languages converge with children's measured language abilities on the Bilingual English Spanish Assessment (BESA), a standardized measure of language ability. 170 kindergarten age children who produced narrative language samples in Spanish and in English based on a wordless picture book were included in the analysis. Samples were analyzed for number of utterances, number of different words, mean length of utterance, and percentage of grammatical utterances. The best predictors of language ability as measured by the BESA scores were English MLU, English grammaticality, and Spanish grammaticality. Results are discussed in relationship to the nature of the measures in each of the languages and in regard to their potential utility for identifying low language ability in bilingual.Learning outcomes: The reader will be able to identify (I) why narratives are useful for evaluating bilingual language ability, (2) which measures of productivity and sentence organization in narratives best capture language ability and development in bilingual children, (3) how a bilingual or composite language ability across two languages can be determined, and (4) what relationship exists between measures of productivity and sentence organization in each language with a bilingual language ability score.
