不同任务下声调和韵母在诗句中的加工过程--来自ERP的证据

The Processing of the Tone and the Vowel in Poems Under Different Tasks:Evidence from ERPs

声调和韵母是声调语言的重要组成部分,以往研究发现二者对言语理解具有不同程度的影响。本研究采用ERP技术,以诗句韵律为媒介,考察普通话母语者在声韵判断和无任务聆听两种任务下,声调和韵母信息的加工过程。结果发现,韵母违反在两种任务中均诱发了P2和LPC,并在声韵判断任务中诱发了N400;声调违反在声韵判断任务中诱发了N400和LPC。结果表明,听者在两种任务中均能于早期快速识别韵母信息,并在晚期完成再分析和整合,而对声调的语音分析和整合过程依赖于听者主动分配认知资源。

Tone and vowel are important components of tone language.Previous studies have found that they have different effects on speech comprehension.The present ERPs study aimed to explore tone and vowel processing in Chinese pomes using prosody judgment and passive listening tasks.The results showed that the vowel violation elicited P2 and LPC in both tasks and elicited N400 in prosody judgment task,while the tone violation elicited N400 and LPC in prosody judgment task.In conclusion,the current study suggests that native Mandarin speakers can quickly detect the vowel violation in the prosody information,and complete the reanalysis and integration of the vowel in the late stage regardless of the kind of task.In contrast to the vowel,the listener only performs the phonological analysis and reanalysis and integration of the tone in the prosody judgment task which relies on cognitive resources being allocated actively by the listeners.
