神经对声音规律的敏感性支持着人类的基本行为，如在噪音中听和阅读。尽管无法对正在进行的言语中的声音规律进行编码与语言和识字缺陷有关，但听觉专长（如与音乐技能相关的专长）与脑干对言语规律的处理之间的关系尚不清楚。考虑到音乐中重复和规律的重要性，音乐技能和神经对声学规律的敏感性之间的联系并不令人惊讶。本研究旨在探讨有和无阅读障碍儿童的皮层下语言规则加工、音乐天赋和阅读能力之间的关系。我们假设，结合听觉认知能力，神经对正在进行的言语规律的敏感性为音乐和阅读能力的发展提供了一种共同的生物学机制。我们评估了42名具有广泛阅读能力的学龄儿童的听觉工作记忆和注意力、音乐天赋、阅读能力和对声音规律的神经敏感性。通过记录脑干对可预测和可变语音流中出现的相同语音的反应来评估神经对声学规律的敏感性。通过相关分析和结构方程模型，我们发现音乐能力和读写能力与皮层下对持续言语规则的适应程度以及听觉工作记忆和注意力有关。音乐和语音处理之间的关系是由音乐节奏任务的表现特别驱动的，强调了语言和音乐节奏规律的重要性。这些数据表明，阅读和音乐能力背后的共同大脑机制与神经系统如何对听觉输入的规律做出反应有关。音乐和阅读的共同生物学基础的定义支持音乐对提高儿童读写能力的有用性，并有可能改善阅读补救。
Neural sensitivity to acoustic regularities supports fundamental human behaviors such as hearing in noise and reading. Although the failure to encode acoustic regularities in ongoing speech has been associated with language and literacy deficits, how auditory expertise, such as the expertise that is associated with musical skill, relates to the brainstem processing of speech regularities is unknown. An association between musical skill and neural sensitivity to acoustic regularities would not be surprising given the importance of repetition and regularity in music. Here, we aimed to define relationships between the subcortical processing of speech regularities, music aptitude, and reading abilities in children with and without reading impairment. We hypothesized that, in combination with auditory cognitive abilities, neural sensitivity to regularities in ongoing speech provides a common biological mechanism underlying the development of music and reading abilities. We assessed auditory working memory and attention, music aptitude, reading ability, and neural sensitivity to acoustic regularities in 42 school-aged children with a wide range of reading ability. Neural sensitivity to acoustic regularities was assessed by recording brainstem responses to the same speech sound presented in predictable and variable speech streams. Through correlation analyses and structural equation modeling, we reveal that music aptitude and literacy both relate to the extent of subcortical adaptation to regularities in ongoing speech as well as with auditory working memory and attention. Relationships between music and speech processing are specifically driven by performance on a musical rhythm task, underscoring the importance of rhythmic regularity for both language and music. These data indicate common brain mechanisms underlying reading and music abilities that relate to how the nervous system responds to regularities in auditory input. Definition of common biological underpinnings for music and reading supports the usefulness of music for promoting child literacy, with the potential to improve reading remediation.
