This project investigates behavioral and neural correlates of German vowel length, in interaction with the tenseness distinction in the German vowel system. In the first part of the project vowel length is investigated in its own right with the distinction between [aj and [aa]. Following up on related experiments in other languages, we want to first document categorical perception of this distinction. Further, we want to study the neural correlates of the additional length unit of the long vowel using MEG in two neurophysiological experiments. In the second part of the project the interaction of vowel length with the tense/lax distinction is investigated. The question under investigation is whether length or tenseness is the crucial (underlying) feature relative to which the other is secondary (derived) in stressed positions. For this purpose, we propose a new experimental design that employs a two-dimensional matrix of acoustic continua in the two dimensions length and tenseness. We expect that the way in which the category-boundary runs through this matrix will provide clear evidence as to whether length or tenseness is perceptually more decisive. This will be tested both in a behavioral experiment and in an MEG experiment.

该项目研究德语元音长度的行为和神经相关性，以及德语元音系统中时态区别的相互作用。在该项目的第一部分中，元音长度本身被研究，并区分 [aj 和 [aa]。在其他语言的相关实验之后，我们希望首先记录对这种区别的分类感知。此外，我们希望在两个神经生理学实验中使用 MEG 研究长元音附加长度单位的神经相关性。在该项目的第二部分中，研究了元音长度与时态/时态区别的相互作用。正在研究的问题是，在受压位置中，长度或紧张度是否是关键（潜在）特征，相对于另一个特征而言，另一个是次要（派生）特征。为此，我们提出了一种新的实验设计，在二维长度和紧张度上采用声学连续体的二维矩阵。我们期望类别边界贯穿该矩阵的方式将提供明确的证据，证明长度或时态在感知上更具决定性。这将在行为实验和脑磁图实验中进行测试。
