Speech‐in‐noise perception is consistently reported to be impaired in learning disorders, which stresses the importance of documenting its developmental course in young children. In this cross‐sectional study, ninety children (41 females, 5.5–11.6 years old) and nineteen normal‐hearing adults (15 females, 20–30 years old) were tested with a newly developed closed‐set speech perception in babble‐noise test, combining two levels of phonological difficulty and two noise levels. Results showed that speech‐in‐babble‐noise perception takes a definite maturation step around 7 years of age (d = 1.17, grade effect) and is not mature at 10 years of age when compared to young adults (d = 0.94, group effect). Developmental trajectories of both accuracy and response times were evaluated, with influences of psycholinguistic factors, to foster the development of adequate screening tests.

5 至 10 岁儿童听觉认知的发展：专注于咿呀学语噪声感知


据报道，学习障碍患者的噪声语音感知受损，这强调了记录其在幼儿中的发展过程的重要性。在这项横断面研究中，90 名儿童（41 名女性，5.5-11.6 岁）和 19 名听力正常的成年人（15 名女性，20-30 岁）在咿呀学语测试中使用新开发的封闭式语音感知进行了测试，结合了两个级别的语音困难和两个噪音级别。结果表明，语音咿呀学语的噪声感知在 7 岁左右有一个明确的成熟步骤（d = 1.17，等级效应），与年轻人相比，在 10 岁时并不成熟（d = 0.94，群体效应）。在心理语言因素的影响下，评估准确性和反应时间的发育轨迹，以促进开发适当的筛查测试。
