节奏将音乐事件组织成模式和形式，音乐中的节奏感知通常通过使用韵律任务来研究。韵律结构也通过语音韵律在语言的音系学中发挥组织功能，并且有证据表明发展性阅读障碍中存在节奏感知困难。在这里，我们探讨了这一假设，即音乐韵律结构的准确感知与上升时间的基本听觉感知有关，也与儿童的语音和识字发展有关。方法：本研究设计了一系列行为任务，旨在探讨音乐韵律知觉、听觉幅度包络结构知觉、对64名发育正常儿童和发展性阅读障碍儿童的语音意识和阅读能力进行了研究。我们发现，振幅包络上升时间感知的个体差异与音乐韵律敏感性有关，音乐韵律敏感性预测PA和阅读发展，解释沿着变化的阅读变异的60%以上。即使是最简单的格律任务，基于双重格律结构，进行显着更差的儿童与dyslexia.Conclusions：准确的感知格律结构可能是至关重要的语音发展，从而为识字的发展。测量处理的困难与基本的听觉上升时间处理困难有关，这表明发育性阅读障碍在跟踪言语包络中的低频调制时存在初级感觉障碍。(C)2010 Elsevier Srl.

Introduction: Rhythm organises musical events into patterns and forms, and rhythm perception in music is usually studied by using metrical tasks. Metrical structure also plays an organisational function in the phonology of language, via speech prosody, and there is evidence for rhythmic perceptual difficulties in developmental dyslexia. Here we investigate the hypothesis that the accurate perception of musical metrical structure is related to basic auditory perception of rise time, and also to phonological and literacy development in children.Methods: A battery of behavioural tasks was devised to explore relations between musical metrical perception, auditory perception of amplitude envelope structure, phonological awareness (PA) and reading in a sample of 64 typically-developing children and children with developmental dyslexia.Results: We show that individual differences in the perception of amplitude envelope rise time are linked to musical metrical sensitivity, and that musical metrical sensitivity predicts PA and reading development, accounting for over 60% of variance in reading along with age and I.Q. Even the simplest metrical task, based on a duple metrical structure, was performed significantly more poorly by the children with dyslexia.Conclusions: The accurate perception of metrical structure may be critical for phonological development and consequently for the development of literacy. Difficulties in metrical processing are associated with basic auditory rise time processing difficulties, suggesting a primary sensory impairment in developmental dyslexia in tracking the lower-frequency modulations in the speech envelope.
