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会受损，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。
