Language and music share many rhythmic properties, such as variations in intensity and duration leading to repeating patterns. Perception of rhythmic properties may rely on cognitive networks that are shared between the two domains. If so, then variability in speech rhythm perception may relate to individual differences in musicality. To examine this possibility, the present study focuses on rhythmic grouping, which is assumed to be guided by a domain-general principle, the Iambic/Trochaic law, stating that sounds alternating in intensity are grouped as strong-weak, and sounds alternating in duration are grouped as weak-strong. German listeners completed a grouping task: They heard streams of syllables alternating in intensity, duration, or neither, and had to indicate whether they perceived a strong-weak or weak-strong pattern. Moreover, their music perception abilities were measured, and they filled out a questionnaire reporting their productive musical experience. Results showed that better musical rhythm perception ability was associated with more consistent rhythmic grouping of speech, while melody perception ability and productive musical experience were not. This suggests shared cognitive procedures in the perception of rhythm in music and speech. Also, the results highlight the relevance of considering individual differences in musicality when aiming to explain variability in prosody perception.

音乐性对语音节奏结构感知的影响

语言和音乐共享许多节奏特性，例如强度和持续时间的变化导致重复模式。对节奏特性的感知可能依赖于两个域之间共享的认知网络。如果是这样，那么语音节奏感知的可变性可能与音乐性的个体差异有关。为了检验这种可能性，本研究侧重于节奏分组，假设该分组受领域一般原则指导，即 Iambic/Trochic 定律，指出强度交替的声音被归为强弱分组，而声音的持续时间交替被分组为弱-强。德国听众完成了一项分组任务：他们听到音节流在强度、持续时间或两者都不交替，并且必须指出他们是否感知到强-弱或弱-强模式。而且，他们测量了他们的音乐感知能力，并填写了一份报告他们富有成效的音乐体验的问卷。结果表明，更好的音乐节奏感知能力与更一致的语音节奏分组相关，而旋律感知能力和富有成效的音乐体验则不然。这表明在感知音乐和语音节奏方面有共同的认知程序。此外，结果强调了在旨在解释韵律感知的可变性时考虑音乐性的个体差异的相关性。而旋律感知能力和富有成效的音乐体验则不然。这表明在感知音乐和语音节奏方面有共同的认知程序。此外，结果强调了在旨在解释韵律感知的可变性时考虑音乐性的个体差异的相关性。而旋律感知能力和富有成效的音乐体验则不然。这表明在感知音乐和语音节奏方面有共同的认知程序。此外，结果强调了在旨在解释韵律感知的可变性时考虑音乐性的个体差异的相关性。
