DESCRIPTION (provided by applicant): Understanding the developmental path to early literacy, which is dependent upon earlier developing language comprehension and production and the activities that support it, is a priority in psychological and educational research. This is consistent with a long-standing focus on identifying those children at greatest risk for language delay early in development. These children are also at risk for difficulties in school. Children with deficits in both comprehension and production are at the greatest risk such that identifying children on the basis of production only results in an under-identification of those most in need of intervention. Language comprehension is central to the development of productive language, literacy, and general cognitive skills but has received limited attention due in part to the difficulty of assessing comprehension early in development. Two primary difficulties limit the measurement of early comprehension: infant distractibility and the portability or ease of test administration in settings outside the lab. A methodology is needed to assess early language comprehension and predict subsequent language and literacy. It must be easily administered by primary care providers and have utility across languages and monolingual and bilingual populations. We propose to address the issues of attention and portability by assessing the long-term predictive validity of the Computerized Comprehension Task. The CCT recruits infant attention to permit direct assessments of vocabulary comprehension in the second year of life. Because the procedure takes only 10 minutes to administer and can be self-contained on any computer with a touch sensitive screen, assessment can be made widely available as part of routine home or office visits. The present studies seek to evaluate the efficacy of the CCT to assess early comprehension across language groups (French, English, Spanish monolinguals and French-English and Spanish- English bilinguals) and to predict developmental outcomes over time including early literacy and school-readiness as children approach kindergarten. This cross-linguistic, longitudinal research will yield a rich picture of the transitions from comprehension to production and from production to early literacy. It will extend a new technology to address the pressing need to identify children at risk for language and literacy difficulties early in development and may facilitate the early identification of children at risk for developmental language disorders such as Specific Language Impairment or Autism Spectrum Disorder.

了解早期识字的发展道路，这取决于早期发展的语言理解和生产以及支持它的活动，是心理和教育研究的优先事项。这与长期以来的重点一致，即确定那些在发展早期语言发育迟缓风险最大的儿童。这些儿童在学校也有可能遇到困难。理解和表达能力都有缺陷的儿童面临的风险最大，因此，根据表达能力来识别儿童只会导致对最需要干预的儿童的识别不足。语言理解是生产性语言，识字和一般认知技能的发展的核心，但受到有限的关注，部分原因是在发展早期评估理解的困难。两个主要的困难限制了早期理解的测量：婴儿的注意力分散和在实验室外的环境中测试管理的便携性或容易性。需要一种方法来评估早期语言理解和预测随后的语言和识字。它必须易于初级保健提供者管理，并具有跨语言和单语和双语人群的实用性。 我们建议通过评估计算机化理解任务的长期预测有效性来解决注意力和可移植性的问题。CCT招募婴儿的注意力，以允许在生命的第二年直接评估词汇理解。由于该程序只需10分钟即可管理，并且可以在任何具有触摸屏的计算机上独立运行，因此可以将评估作为日常家庭或办公室访问的一部分广泛使用。本研究旨在评估CCT的有效性，以评估跨语言群体（法语，英语，西班牙语单语和法语-英语和西班牙语-英语双语）的早期理解，并预测随着时间的推移，包括早期识字和入学准备的儿童接近幼儿园的发展成果。 这种跨语言的纵向研究将产生从理解到生产和从生产到早期识字过渡的丰富画面。它将扩展一项新技术，以满足在发展早期识别有语言和识字困难风险的儿童的迫切需要，并可能促进早期识别有发展性语言障碍风险的儿童，如特殊语言障碍或自闭症谱系障碍。
