In the present study, the time course of tonal and vowel information processing of the spoken words in Mandarin Chinese was investigated using a delayed-response paradigm. Idiomatic materials, providing semantically highly constraining contexts, were utilized. Besides being presented normally, the terminal monosyllabic words in idioms were manipulated with Tonal, Vowel, or Triple violations (i.e. with consonantal, tonal, and vowel mismatches). Event-related potential results showed that all three violations elicited larger widespread negativities in comparison with the Control condition, with the Triple violation effect starting first from 150 ms, then the Vowel violation, and the Tonal violation being the latest. The different starting times of the violation effects suggest that the access of tonal information is slower than that of vowel information, even though the lexical tones are very important in distinguishing the meaning of Chinese words.
在本研究中，使用延迟反应范式研究了汉语口语中声调与元音信息处理的时间进程。采用了具有语义高度约束性语境的惯用语材料。除了正常呈现外，对习语中的结尾单音节词进行了声调、元音或三重违反操作（即辅音、声调及元音不匹配）。事件相关电位结果表明，与对照条件相比，所有三种违反操作均引发了更广泛的负波，三重违反效应最早从150毫秒开始出现，其次是元音违反，声调违反最晚出现。违反效应的不同起始时间表明，尽管词汇声调在区分汉语词义方面非常重要，但声调信息的获取比元音信息要慢。
