Recent evidence suggests the existence of shared neural resources for rhythm processing in language and music. Such overlaps could be the basis of the facilitating effect of regular musical rhythm on spoken word processing previously reported for typical children and adults, as well as adults with Parkinson's disease and children with developmental language disorders. The present study builds upon these previous findings by examining whether non-linguistic rhythmic priming also influences visual word processing, and the extent to which such cross-modal priming effect of rhythm is related to individual differences in musical aptitude and reading skills. An electroencephalogram (EEG) was recorded while participants listened to a rhythmic tone prime, followed by a visual target word with a stress pattern that either matched or mismatched the rhythmic structure of the auditory prime. Participants were also administered standardized assessments of musical aptitude and reading achievement. Event-related potentials (ERPs) elicited by target words with a mismatching stress pattern showed an increased fronto-central negativity. Additionally, the size of the negative effect correlated with individual differences in musical rhythm aptitude and reading comprehension skills. Results support the existence of shared neurocognitive resources for linguistic and musical rhythm processing, and have important implications for the use of rhythm-based activities for reading interventions.
最近的证据表明，语言和音乐的节奏处理存在共享的神经资源。这种重叠可能是先前报道的常规音乐节奏对典型儿童和成人、帕金森病成人患者以及发育性语言障碍儿童的口语处理产生促进作用的基础。本研究基于这些先前的发现，通过检验非语言节奏启动是否也会影响视觉单词处理，以及这种节奏的跨模态启动效应在多大程度上与音乐才能和阅读技能的个体差异相关。在参与者听有节奏的音调启动刺激后，记录其脑电图（EEG），随后呈现一个视觉目标单词，其重音模式与听觉启动刺激的节奏结构匹配或不匹配。参与者还接受了音乐才能和阅读成绩的标准化评估。由重音模式不匹配的目标单词引发的事件相关电位（ERP）显示额中央负波增加。此外，这种负效应的大小与音乐节奏才能和阅读理解技能的个体差异相关。研究结果支持了语言和音乐节奏处理存在共享神经认知资源的观点，并对基于节奏的活动在阅读干预中的应用具有重要意义。
