A widely accepted view of speech perception holds that in order to comprehend language, the variable acoustic signal must be parsed into a set of abstract linguistic representations. However, the neural basis of early phonological processing, including the nature of featural encoding of speech, is still poorly understood. In part, progress in this domain has been constrained by the difficulty inherent in extricating the influence of acoustic modulations from those which can be ascribed to the abstract, featural content of the stimuli. A further concern is that group averaging techniques may obscure subtle individual differences in cortical regions involved in early language processing. In this paper we present the results of an fMRI-adaptation experiment which finds evidence of areas in the superior and medial temporal lobes which respond selectively to changes in the major feature categories of voicing and place of articulation. We present both single-subject and group-averaged analyses.

使用 fMRI-adaptation 对地点和语音特征的调查

一种广泛接受的语音感知观点认为，为了理解语言，必须将可变声学信号解析为一组抽象的语言表示。然而，早期语音处理的神经基础，包括语音特征编码的性质，仍然知之甚少。在某种程度上，该领域的进展受到了从可归因于刺激的抽象特征内容的声学调制的影响中固有的困难的限制。另一个问题是，群体平均技术可能会掩盖早期语言处理中涉及的皮层区域的细微个体差异。在本文中，我们展示了 fMRI 适应实验的结果，该实验发现了上颞叶和内侧颞叶区域的证据，这些区域对发声和发音位置的主要特征类别的变化有选择性地做出反应。我们提供单受试者和组平均分析。
