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:  A central issue in written production concerns how phonological codes influence the output of orthographic codes. The obligatory phonological mediation hypothesis assumes that the retrieval of an orthographic representation was entirely dependent on the prior retrieval of phonological codes. By contrast, the orthographic autonomy hypothesis assumes that individuals can gain access to orthographic representation directly from meaning without phonological mediation. In a picture names writing task, we used the event-related potential (ERP) technique to examine the time course of the word frequency facilitation effect and the syllable frequency facilitation effect in Chinese handwritten production in the old. Twenty-two participants (10 males, age range: 64~81 years) participated in this study. Sixty black and white line drawings with monosyllabic words were chosen as stimuli. The experimental design included word frequency of picture names (high vs. low) and syllable frequency of picture names (high vs. low) as within-participants and between-items variables. During the experiment, participants were instructed to write picture names as fast and accurately as possible. Behavioral data indicated the facilitation effects of word frequency and syllable frequency. Writing latencies were faster in picture names with high word frequency than those with low word frequency. Similarly, writing latencies were faster in picture names with high syllable frequency than those with low syllable frequency. There was no significant interaction between word frequency and syllable frequency for behavioral data. ERP data indicated that: (1) in the time window of 200~300 ms after pictures onset, we found independent word frequency effect and syllable frequency effect. The interaction between two variables was absent. (2) in the time window of 300~600 ms after pictures onset, we found the interaction between word frequency and syllable frequency, and distinct map distributions for both effects. (3) the onset latencies of word frequency and syllable frequency effects were 212 ms and 238 ms, respectively. We therefore suggest that the early word frequency effect may originate from the retrieval of orthographic information in the orthographic lexicon, while the early syllable frequency effect may originate from the retrieval of phonological information in the phonological lexicon. The syllable frequency, as a type of phonological information, influences the relatively late stage of written production. Our findings thus provide evidences for the orthography autonomy hypothesis, rather than the phonological mediation hypothesis.
