Prosodic pattern recognition of high-frequency POS-grams and Phrase-frames

本研究旨在探讨日本英语学习者是否能识别构成短语范畴的词性串的韵律模式。韵律模式匹配任务的结果表明，高、低水平学习者在识别高频和低频POS-语法的韵律模式上没有差异。英语本族语者的成绩优于英语学习者，尤其是在英语本族语者语料库中出现频率较高而非英语学习者语料库中出现频率较低的短语类别上。有趣的是，非短语类别在NS和NNS之间的识别水平相同。研究结果表明，尽管普通话和非普通话在短语类别的韵律模式识别上存在差异，但这并不是影响听力和阅读理解技能的关键因素，而听力和阅读理解技能是通过TOIEC成绩区分高水平和低水平学习者的关键因素。

This study examined whether Japanese learners of English could recognize the prosodic pattern of a string of part-of-speech (POS-gram) which constitute a phrasal category. The results of prosodic pattern-matching task showed that there was no difference in the performance between advanced and lower level learners in recognizing the prosodic pattern of high and low frequency POS-grams. Native speakers of English (NS) outperformed English learners (NNS) especially on the phrasal categories which appeared frequently in the NS corpus but not in the NNS corpus. Interestingly, non-phrasal categories were recognized at the same level between NS and NNS. The results suggest that although NS and NNS differ in their performance of recognizing prosodic pattern of a phrasal category, it is not a crucial factor that affects listening and reading comprehension skills which divides advanced level learners from lower level learners by their TOIEC scores.
