PROJECT SUMMARY/ABSTRACT The goal of this project is to characterize the speech perception and auditory abilities of infants, children, and adults with Down syndrome. Prior research involving individuals who are neurotypical has highlighted the importance of early perceptual development on long-term speech and language outcomes, but little is currently known about the factors that support communication outcomes for individuals with Down syndrome. We do know that the development of functional hearing skills in children who are neurotypical (such as understanding speech when several people are talking at the same time) requires years of experience with sound, extensive language knowledge, and maturation of executive function. These observations suggest that attainment of speech perception and hearing milestones is likely to be delayed or disrupted for children with Down syndrome, due to limitations in intellectual functioning, language knowledge, and cognitive processing. The first aim of this project evaluates phoneme perception in infants, children, and adults with Down syndrome, with a focus on characterizing infants’ discrimination of native and non-native speech contrasts and examining effects of hearing loss on the consonant identification in children and adults. The second aim tests the hypothesis that maturation of selective listening strategies follows a delayed time course of development for individuals with Down syndrome, resulting in greater susceptibility to interference from competing background sounds. The third aim characterizes the ability to recognize speech in the presence of competing background sounds in children and adults with Down syndrome, accounting for individual differences in factors such as linguistic knowledge and working memory. The results generated by this project are expected to inform theoretical models regarding the development of speech perception and hearing abilities in individuals with Down syndrome, and have the potential to provide preliminary guidance for strategies to maximize speech communication outcomes in noisy environments such as classrooms.

项目摘要/摘要 该项目的目的是表征婴儿，儿童， 和唐氏综合症的成年人。涉及神经型的个体的事先研究强调了 早期感知发展对长期语音和语言结果的重要性，但目前几乎没有 知道支持唐氏综合症个体的交流结果的因素。我们知道 神经典型儿童的功能听力技能的发展（例如理解语音 当几个人同时说话时）需要多年的声音，广泛的语言经验 知识和执行功能的成熟。这些观察表明，言语达成 由于唐氏综合症儿童的感知和听力里程碑可能会延迟或破坏 智力功能，语言知识和认知处理的局限性。该项目的第一个目标 评估婴儿，儿童和唐氏综合症成年人的音素感知，重点 表征婴儿对本地和非本地语音对比的歧视并检查听力的影响 儿童和成人辅音识别的损失。第二个目标检验了成熟的假设 选择性聆听策略遵循有降低的个人的时间发展延迟 综合征，导致对竞争背景声音干扰的敏感性更大。第三个目标 表征在儿童存在竞争背景的情况下识别语音的能力， 患有唐氏综合症的成年人，考虑了语言知识和等因素的个体差异 工作记忆。预计该项目产生的结果将为理论模型提供有关 唐氏综合症患者的言语感知和听力能力的发展，并具有 为策略提供初步指导，以最大程度地提高噪音中语音交流结果 教室等环境。
