摘要: 摘 要 运用事件相关电位(ERP)技术考查了在汉语词汇产生过程中,语义提取和语音提取的时间进程。在实验过程中,给被试呈现一张图片,要求他们在小声进行图片命名之前,先基于语义信息(图上画的是物体还是动物)或语音信息(如图片名称是以字母s还是以y开头)完成一个双重选择任务。在一种情况下,反应手(左手或右手按键)由语义信息决定,是否反应(GO/NOGO)由语音信息决定;在另一种情况下,反应手由语音信息决定,是否反应由语义信息决定。结果发现,当是否反应由语义信息(动物/物体)决定时,N200的潜伏期是307ms;当是否反应由语音信息(如中文名称以S/Y开头)决定时,N200的潜伏期是447ms;两者之间存在显著的差异,即由语义信息引起的N200的潜伏期早于由语音信息引起的N200的潜伏期。结果表明,在汉语词汇产生过程中,语义提取先于语音提取。

Abstract: The temporal course of semantic and phonological retrieval in Chinese word production was investigated using ERP technique. Participants were shown pictures and required to carry out a dual choice GO/NOGO task based on the semantic information (i.e., whether the picture was of an object or an animal) and phonological information (e.g., whether the picture’s Chinese name starts with the letter Y or S). The N200 data indicated that semantic retrieval preceded phonological retrieval during Chinese word production, which was consistent with many previous findings. These data are discussed based on the related theory of speech production.
