Examination of the Dual Mechanism Model for First and Second Language Acquisition.

本研究旨在探讨第二语言习得中的词法问题，并检验两个假说的有效性，即表征缺陷假说（RDH）（Hawkins，2001 ; Hawkins & Liszka，2003）和韵律迁移假说（PTH）（Goad，Steel &白色，2003 ; Goad &白色，2004 ; 2006）。对汉语学习者的测试发现，尽管有些汉语学习者在过去时态变化方面有困难，但其他人能够使用日语过去时态变化。可靠地，无论是书面形式和自发生产。因此，我们的结果支持PTH。

This study addresses the issue of morphology in second language(L2) acquisition, and examines the validity of two hypotheses which have been proposed to explain the cause of such difficulties, namely the Representational Deficit Hypothesis(RDH)(Hawkins, 2001 ; Hawkins & Liszka, 2003) and the Prosodic Transfer Hypothesis(PTH)(Goad, Steel & White, 2003 ; Goad & White, 2004 ; 2006). Testing the Chinese-speaking learners, it was found that although some Chinese speakers had difficulties with past tense inflection, others were able to use the Japanese past tense inflection. ta reliably, both in written form and spontaneous production. Therefore, our results support the PTH.
