【摘要】：本研究运用事件相关电位技术,考察了老年人(60岁以上)汉语词汇书写产生过程中的词汇频率效应和音节频率效应的时间进程。实验中采用图画命名范式,要求被试在看到图画之后迅速且准确地写出相应的名称。结果表明:词汇频率和音节频率影响汉字书写的潜伏期,表现为高词汇频率词的书写潜伏期短于低词汇频率词,高音节频率词的书写潜伏期短于低音节频率词;在书写产生的早期阶段,词频与音节频率效应独立发生,早期词频效应可能来源于正字法词典中信息的提取,早期音节频率效应可能来源于语音词典中对音节的提取,且词频效应早于音节频率效应,这为"正字法自主假设"提供了支持证据。在书写产生的晚期阶段,词频和音节频率之间存在交互作用,这可能是由于语音词典和正字法词典之间的双向联结,激活的双向扩散引起的。语音信息在书写产生过程被激活,在较晚的阶段影响了正字法编码过程。
[Abstract]:The present study investigated the temporal processes of lexical frequency effect and syllable frequency effect in the process of Chinese lexical writing by using event-related potential technique. In the experiment, using the picture naming paradigm, the subjects were asked to write out the corresponding names quickly and accurately after seeing the pictures. The results show that lexical frequency and syllable frequency affect the latent period of Chinese character writing, which shows that the writing latency of high vocabulary frequency words is shorter than that of low vocabulary frequency words, and the writing latency of high syllable frequency words is shorter than that of low syllable frequency words. In the early stage of writing, word frequency and syllable frequency effect occur independently. The early word frequency effect may come from the extraction of information in orthographic dictionaries, and the early syllable frequency effect may come from the extraction of syllables in phonetic dictionaries. The word frequency effect is earlier than the syllable frequency effect, which supports the orthographic hypothesis. In the late stage of writing, there is interaction between word frequency and syllable frequency, which may be caused by the bidirectional connection and active bidirectional diffusion between phonetic dictionary and orthographic dictionary. Speech information is activated in the writing process and affects the orthographic coding process at a later stage.
