Investigations of how we produce and perceive prosodic patterns are not only interesting in their own right but can inform fundamental questions in language research. We here argue that functional magnetic resonance imaging (fMRI) in general - and the functional localization approach in particular (e.g., Kanwisher et al., 1997; Saxe et al., 2006; Fedorenko et al., 2010; Nieto-Castañon & Fedorenko, 2012) - has the potential to help address open research questions in prosody research and at the intersection of prosody and other domains. Critically, this approach can go beyond questions like "where in the brain does mental process produce activation" and toward questions that probe the nature of the representations and computations that subserve different mental abilities. We describe one way to functionally define regions sensitive to sentence-level prosody in individual subjects. This or similar "localizer" contrasts can be used in future studies to test hypotheses about the precise contributions of prosody-sensitive brain regions to prosodic processing and cognition more broadly.
对我们如何产生和感知韵律模式的研究不仅本身很有趣,而且可以为语言研究中的基本问题提供信息。我们在此认为,一般的功能磁共振成像(fMRI)——尤其是功能定位方法(例如,Kanwisher等人,1997年;Saxe等人,2006年;Fedorenko等人,2010年;Nieto-Castañon和Fedorenko,2012年)——有潜力帮助解决韵律研究以及韵律与其他领域交叉处的开放性研究问题。至关重要的是,这种方法可以超越“大脑中的哪个部位会因心理过程而产生激活”这样的问题,进而探讨支持不同心理能力的表征和计算的本质问题。我们描述了一种在个体受试者中从功能上定义对句子层面韵律敏感区域的方法。这种或类似的“定位器”对比可用于未来的研究,以更广泛地检验关于韵律敏感脑区对韵律处理和认知的确切贡献的假设。
