项目摘要

During the first year of life, infants begin to vocalize, and their cooing and babbling become increasingly more sophisticated and complex, paving the way for speech. Infants' vocalizations often occur in strings or clusters of similar-sounding vocalizations. Caregivers frequently respond to babies' vocalizations even before they can talk, and adults vary their responses depending on the types of vocalization babies produce. These adult responses appear to influence babies' subsequent vocalizations. This research offers a new explanatory perspective on infant vocalization by borrowing ideas from what we know about how animals forage, systematically exploring an environment to find food. When foraging, animals strike a balance between revisiting familiar locations where food has been found and trying out new locations that may lead to undiscovered resources. This project will advance understanding of how infants refine their vocal abilities by considering prelinguistic infants as foragers who explore the range of possible vocalizations in search of interesting or useful feedback, including positive responses from adults.Daylong home audio recordings will be collected from English- and Spanish-learning infants at 3, 6, 9, and 18 months of age. Infant vocalizations will be automatically identified and analyzed acoustically, then situated in an abstract acoustic information space. For each region of acoustic space, the likelihood of receiving an adult response will be ascertained. Methods previously developed to analyze patterns of foraging for resources in physical space will be applied. Adult vocalization acoustics and their relationship to infant vocal foraging responses will be similarly analyzed. Computational models of infant and adult vocal foraging will be employed to explore possible mechanisms that underlie the observed temporal dynamics of infant and adult vocalizations over the course of the day. Vocal foraging measures will be tested for changes across age and with socioeconomic status. Whether foraging patterns during the first year predict speech-language abilities at 18 months will also be tested. The work has the potential to unveil new candidates for automatically obtainable markers that could be useful for early identification of children at risk for speech-language delays or disorders.
在生命的第一年,婴儿开始发声,他们的咕咕声和牙牙学语变得越来越复杂,为说话铺平了道路。婴儿的发声通常是一连串或一串发音相似的发声。 照顾者经常对婴儿的发声做出反应,甚至在他们能说话之前,成年人的反应取决于婴儿发出的声音类型。 这些成人的反应似乎会影响婴儿随后的发声。 这项研究提供了一个新的解释婴儿发声的角度,借用我们所知道的动物如何觅食的想法,系统地探索一个环境来寻找食物。在觅食时,动物会在重访已发现食物的熟悉地点和尝试可能导致未发现资源的新地点之间取得平衡。 本项目将进一步了解婴儿如何完善他们的发声能力,考虑前语言婴儿觅食谁探索可能的发声范围内寻找有趣的或有用的反馈,包括来自成人的积极回应。为期一天的家庭录音将收集从英语和西班牙语学习的婴儿在3,6,9,和18个月大。婴儿发声将被自动识别和分析声学,然后位于一个抽象的声学信息空间。对于声学空间的每个区域,将确定接收成人响应的可能性。将应用以前开发的方法来分析在物理空间中觅食资源的模式。成人发声声学和他们的关系,婴儿的声音觅食反应将进行类似的分析。计算模型的婴儿和成人的声音觅食将探讨可能的机制,所观察到的时间动态的婴儿和成人发声的过程中的一天。声音觅食的措施将进行测试的变化,随着年龄和社会经济地位。第一年的觅食模式是否能预测18个月时的语言能力也将被测试。这项工作有可能为自动获得的标记物揭开新的候选者,这些标记物可能有助于早期识别有语言延迟或障碍风险的儿童。
