Project Summary: Children with language disorders are at risk for a host of negative health and academic consequences, and represent at least 7% of the school-aged population. This project addresses two critical public-health needs regarding language disorders: (1) Characterizing early language skill trajectories with the goal of (2) Improving early identification. The administrative supplement, supported by the Tackling Acquisition of Language in Kids (TALK) initiative seeks to expand the ability of the parent grant to build a wider array of assessments into a longitudinal study that examines language development trajectories in children with a wide range of language skills between the ages of 18 to 48 months. Specifically, this supplement will allow us to add new expertise to our team that can support new analysis of existing vocabulary trajectories in the dataset (Aim 1), and will support an additional wave of data collection when children in the sample are 3-years of age (Aim 2). Specifically, Aim 2 measures will focus on adding measures to assess aspects of language, speech, and pre- literacy skills that extend beyond the parent grant focus on lexico-semantic skills. These new measures from Aim 1 and 2 will then support future analysis (Aim 3) of how the new measures from Aim 1 and 2 relate to planned measures in the parent grant that assess language, speech, and literacy skills at age 4. This project will therefore advance our understanding of early language growth trajectories in children with and without early delays in communicative skills, and will enhance our ability to detect early language disorders by supporting a wider range of potential markers longer-term delays that extend beyond the scope of the parent grant.

项目摘要： 语言障碍的儿童面临许多负面健康和学术后果的风险，并且 至少占学龄人口的7％。该项目满足了两个关键的公共卫生需求 关于语言障碍：（1）以（2）改进的目标来表征早期语言技能轨迹 早期识别。行政补充，在儿童中处理语言的支持支持 （谈话）主动权旨在将父母赠款建立更广泛评估的能力扩大到一个 纵向研究检查了具有广泛语言的儿童语言发展轨迹 18至48个月的年龄之间的技能。具体而言，这种补充剂将使我们能够为 我们的团队可以支持对数据集中现有词汇轨迹的新分析（AIM 1），并将 当样本中的儿童年龄3岁时，支持额外的数据收集浪潮（AIM 2）。 具体而言，AIM 2措施将着重于添加措施来评估语言，语音和前的方面 扫盲技能超出了父母赠款的关注，关注词典语义技能。这些新措施来自 AIM 1和2将支持未来分析（目标3）AIM 1和2的新措施如何与 父母赠款的计划措施评估4岁时的语言，语音和扫盲技能。该项目 因此，将进一步了解我们对患有和没有的儿童的早期语言成长轨迹 交流技能的早期延迟，并将增强我们检测早期语言障碍的能力 支持更广泛的潜在标记长期延迟，这些标记超出了父母的范围 授予。
