Previous research indicates that temporal accents (TAs; accents due to time changes) play a strong role in meter perception, but evidence favoring a role for melodic accents (MAs; accents due to pitch changes) is mixed. The authors claim that this mixed support for MAs is the result of a failure to control for accent salience and addressed this hypothesis in Experiment 1. Listeners rated the metrical clarity of 13-tone melodies in which the magnitude and pattern of MAs and TAs were varied. Results showed that metrical clarity increased with both MA and TA magnitude. In Experiment 2, listeners were asked to rate metrical clarity in melodies with combinations of MA and TA patterns to allow the authors to ascertain whether these two accent types combined additively or interactively in meter perception. With respect to the additive or interactive debate, the findings highlighted the importance of (a) accent salience, (b) scoring methods, and (c) conceptual versus statistical interpretations of data. Implications for dynamic attending and neuropsychological investigations are discussed.
先前的研究表明，时间重音（TA；由时间变化引起的重音）在节拍感知中起着重要作用，但支持旋律重音（MA；由音高变化引起的重音）作用的证据并不一致。作者声称，对MA的这种混合支持是由于未能控制重音显著性所致，并在实验1中验证了这一假设。听众对13音旋律的节拍清晰度进行评分，其中MA和TA的大小和模式各不相同。结果表明，节拍清晰度随着MA和TA大小的增加而提高。在实验2中，要求听众对具有MA和TA模式组合的旋律的节拍清晰度进行评分，以便作者确定这两种重音类型在节拍感知中是相加还是相互作用。关于相加或相互作用的争论，研究结果突出了（a）重音显著性、（b）评分方法以及（c）数据的概念性与统计性解释的重要性。文中还讨论了对动态注意力和神经心理学研究的启示。
