聲調和韻母是聲調語言的重要組成部分,以往研究發現二者對言語理解具有不同程度的影響。本研究采用ERP技術,以詩句韻律為媒介,考察普通話母語者在聲韻判斷和無任務聆聽兩種任務下,聲調和韻母信息的加工過程。結果發現,韻母違反在兩種任務中均誘發了P2和LPC,并在聲韻判斷任務中誘發了N400;聲調違反在聲韻判斷任務中誘發了N400和LPC。結果表明,聽者在兩種任務中均能于早期快速識別韻母信息,并在晚期完成再分析和整合,而對聲調的語音分析和整合過程依賴于聽者主動分配認知資源。

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.
