项目摘要

This project looks at two major issues in psycholinguistics. The first one concerns segmentation of the speech stream for word recognition, and the second one the role of morphology in accessing and organizing the mental lexicon. Given that there are no clear word boundaries in spoken language, much research has been dedicated to understanding how the speech processing system manages to isolate words. On the other hand, a large body of research on morphology has argued that morphologically complex words are decomposed into morphemes during word recognition. Previous research on morphological processing, however, has mainly dealt with visually presented isolated words. The present project proposes to combine the two aspects of word recognition, i.e., segmentation of the speech stream at word boundaries and segmentation of complex words into component morphemes, to see if auditorily presented morphologically complex words are decomposed and if this decomposition follows general rules of connected speech segmentation. Planned behavioral and EEG experiments will more specifically look at how morphological processing interacts with phonological processing, and if phonological change of the realisation of the stem and the affix influence the decomposition process. In particular, we will see if phonological alternations at morpheme boundaries, such as resyllabification or segment deletion, prevent morphological segmentation. Moreover, further investigations will look at the status of the units activated in the mental lexicon during word recognition. Indeed, even if morphemes are extracted and their representations activated during word identification, it is still necessary to establish if they are represented as words or if they corresponded to another level of representation, as suggested in various theoretical approaches. In a set of behavioural and EEG experiments we will look at the status of morphemes in the mental lexicon, as compared to the status of free words. This collaboration of the German and the French teams will bring together two partners with joint interests in the general research questions on the one hand and complementary methodological expertise on the other, the French partner having a stronger background in psycholinguistics, and the German partner, in neurolinguistics and linguistics.

这个项目着眼于心理语言学中的两个主要问题。第一部分研究语音流的词识别分割，第二部分研究词法在获取和组织心理词汇中的作用。鉴于口语中没有明确的单词边界，很多研究都致力于理解语音处理系统是如何隔离单词的。另一方面，大量的形态学研究认为，词形复杂的词在识别过程中被分解成语素。然而，以往的形态学处理研究主要是处理视觉呈现的孤立词。本项目提出将词识别的两个方面结合起来，即在词边界处对语音流进行分词和将复杂词分词为成分语素，看听觉上呈现的形态复杂词是否被分解，这种分解是否遵循连通语音分词的一般规则。计划中的行为和脑电图实验将更具体地研究形态处理如何与语音处理相互作用，以及词干和词缀实现的语音变化是否影响分解过程。特别是，我们将看到语素边界的音位变化，如重音节或片段删除，是否会阻止形态分割。此外，进一步的研究将着眼于在单词识别过程中激活的心理词汇单元的状态。事实上，即使在单词识别过程中提取了语素并激活了它们的表征，仍然有必要确定它们是被表征为单词，还是像各种理论方法所建议的那样对应于另一个表征水平。在一系列的行为和脑电图实验中，我们将观察语素在心理词汇中的地位，并将其与自由词的地位进行比较。德国和法国团队的这次合作将把两个合作伙伴聚集在一起，一方面对一般研究问题有共同兴趣，另一方面在方法论上有互补的专业知识，法国合作伙伴在心理语言学方面有更强的背景，德国合作伙伴在神经语言学和语言学方面有更强的背景。
