Twenty-five years ago, the publication of an article by Pallier, Colomé, and Sebastián-Gallés (2001) launched a new and rapidly evolving research program on how second language (L2) learners represent the phonological forms of words in their mental lexicons. Many insights are starting to form an overall picture of the unique difficulties for establishing functional and precise phonolexical representations in L2; however, for the field to move forward it is pertinent to outline its major emerging research questions and existing challenges. Among significant obstacles for further research, the paper explores the current lack of theoretical agreement on the concept of phonolexical representations and the underlying mechanism involved in establishing them, as well as the variable use of the related terminology (e.g., fuzziness and target-likeness). Methodological challenges involved in investigating phonological processing and phonolexical representations as well as their theoretical implications are also discussed. To conclude, we explore the significance of L2-specific phonological representations for the bottom-up lexical access during casual, conversational speech and how our emerging knowledge of L2 lexical representations can be applied in an instructional setting as two potentially fruitful research avenues at the forefront of the current research agenda.

语音处理和 L2 心理词典


25 年前，Pallier、Colomé 和 Sebastián-Gallés （2001） 发表了一篇文章，启动了一项新的、快速发展的研究计划，研究第二语言 （L2） 学习者如何在他们的心理词典中表示单词的语音形式。许多见解开始形成一个整体，即在 L2 中建立功能性和精确的语音表示的独特困难;然而，为了使该领域向前发展，概述其主要的新兴研究问题和现有挑战是相关的。在进一步研究的重大障碍中，本文探讨了目前对语音表示的概念和建立它们所涉及的潜在机制缺乏理论共识，以及相关术语的可变使用（例如，模糊性和目标相似性）。还讨论了研究语音处理和语音表示所涉及的方法挑战及其理论意义。总而言之，我们探讨了 L2 特定语音表示对随意对话期间自下而上的词汇访问的重要性，以及我们新兴的 L2 词汇表示知识如何应用于教学环境中，作为当前研究议程前沿的两个可能富有成效的研究途径。
