PROJECT SUMMARY: Congenitally blind children with co-morbid hearing loss (DeafBlind children) often experience severe language delays due to their multisensory losses. These delays often lead to misidentification of these children as Developmentally Delayed and subsequently negatively impact intervention, rehabilitation, and educational efforts. Providing early, accessible language may address this issue by scaffolding early cognitive development. However, current rehabilitation approaches have extremely limited success. Existing interventions rely on establishing associations between an object the child touches (e.g., shoes), and a specific functional activity (e.g., going outside). This approach lacks the linguistic structures needed for early cognitive development. Only in later childhood do interventions begin to use visual sign language and/or spoken language. This approach poses two major problems: First, neither of these languages is fully accessible for DeafBlind children. Second, by the time language is introduced, many children are past the age at which language can be effectively acquired (i.e., the critical period for language). Consequently, only a small number of DeafBlind children acquire effective communication and achieve age- appropriate cognitive, and daily life milestones. Until recently, no fully accessible language for DeafBlind children existed. Protactile is a fully tactile language that has recently developed among DeafBlind adults. This research endeavor focuses on measuring how well protactile can serve as an early language for DeafBlind children. Adult Protactile Experts who are DeafBlind will play with DeafBlind children using protactile multiple times per week in a longitudinal study. We will use number language to index the efficacy of the intervention. Number language serves as an excellent index because it provides a targeted set of vocabulary items to measure, is directly linked to cognitive development, and has non-linguistic perception-based abilities that have been found in typically developing infants. The specific aims of this study are: (1) Intervention: Identify which tactile number expressions produced by DeafBlind adults are learned by DeafBlind children, (2) Prototype Development: Develop a haptic device to be worn by DeafBlind children that delivers taps and squeezes and also measures heart rate patterns, and (3) Non-linguistic Assessment: Using the wearable device and heart rate patterns, we will demonstrate whether DeafBlind children perceive differences between different numbers of taps or squeezes produced by the device. We expect that DeafBlind children will express protactile number language, and that our haptic measure will reveal non-linguistic abilities similar to typically developing children. This project will generate evidence regarding the use of protactile in early intervention, supporting the achievement of early developmental milestones in DeafBlind children and contributing to their long-term quality of life. Further, successful completion will contribute to the development of nonlinguistic measures of cognition in DeafBlind children and other children with whom visual measures are not suitable.

项目摘要：经常有盲人听力损失（聋哑儿童） 由于其多感官损失，经历严重的语言延迟。这些延误通常会导致 这些孩子的错误识别是发育迟缓，随后对 干预，康复和教育工作。提供早期，可访问的语言可能会解决这个问题 通过脚手架早期认知发展的问题。但是，当前的康复方法极为 有限的成功。现有的干预措施依赖于孩子接触的对象之间建立关联 （例如，鞋子）和特定的功能活动（例如，出门在外）。这种方法缺乏语言 早期认知发展所需的结构。只有在后来的童年时期，干预措施才开始使用视觉 手语和/或口语。这种方法提出了两个主要问题：首先，这些都不 聋哑儿童可以完全使用语言。其次，在介绍时代语言的情况下，许多孩子 是可以有效获取语言的年龄（即语言的关键时期）。 因此，只有少数聋哑儿童获得有效的沟通并实现年龄 - 适当的认知和日常生活里程碑。直到最近，聋哑人都没有完全访问的语言 儿童存在。 Protactile是一种完全触觉的语言，最近在聋哑成年人中发展了。这 研究努力专注于衡量Protactile如何用作聋哑人的早期语言 孩子们。聋哑人的成人原始专家将使用Protactile多重玩耍与聋哑儿童一起玩 纵向研究中的每周时间。我们将使用数字语言来索引干预的功效。 数字语言是一个出色的索引 测量，与认知发展直接相关，并且具有非语言感知能力 在典型发育的婴儿中发现。这项研究的具体目的是：（1）干预：确定哪个 聋哑成年人产生的触觉数量表达式是聋哑儿童学习的，（2）原型 开发：开发聋哑儿童戴上触觉装置，可提供水龙头和挤压和 还可以测量心率模式，（3）非语言评估：使用可穿戴设备和心脏 速率模式，我们将证明聋哑儿童是否感知不同数字之间的差异 设备产生的水龙头或挤压。我们预计聋哑儿童将表达Protactile号码 语言，我们的触觉措施将揭示类似于通常发展的儿童的非语言能力。 该项目将生成有关在早期干预中使用Protactile的证据，并支持 在聋哑儿童中实现早期发展里程碑，并为他们的长期质量做出贡献 生活。此外，成功完成将有助于发展非语言认知措施 在聋哑儿童和其他与视觉措施不合适的儿童中。
