This study used Event-Related Potentials (ERPs) to explore the role of input-based structure-specific proficiency in L2 syntactic processing, using English subject-verb agreement structures as the stimuli. A pre-test/trainings/post-test paradigm of experimental and control groups was employed, and Chinese speakers who learned English as a second language (L2) participated in the experiment. At pre-test, no ERP component related to the subject-verb agreement structures violations was observed in either group. At training session, the experimental group learned the subject-verb agreement structures, while the control group learned other syntactic structures. After two continuously intensive input trainings, at post-test, a significant P600 component related to the subject-verb agreement structures violations was elicited in the experimental group, but not in the control group. These findings suggest that input training improves structure-specific proficiency, which is reflected in the neural mechanism of L2 syntactic processing.
本研究使用事件相关电位（ERP），以英语主谓一致结构作为刺激，探讨基于输入的特定结构熟练度在二语句法加工中的作用。采用实验组和对照组的前测/训练/后测范式，以汉语为母语且将英语作为第二语言（L2）学习的学习者参与了该实验。在前测中，两组均未观察到与主谓一致结构违反相关的ERP成分。在训练阶段，实验组学习主谓一致结构，而对照组学习其他句法结构。经过两次连续的强化输入训练后，在后测中，实验组诱发了与主谓一致结构违反相关的显著P600成分，而对照组未诱发。这些发现表明，输入训练提高了特定结构的熟练度，这在二语句法加工的神经机制中得到体现。
